  • The standard for AA-LDHI has been set!

    Clariant’s Manufacturing Investment Ensures Supply of Anti Agglomerate (AA) Low Dose Hydrate Inhibitor (LDHI) 
    Since Clariant began the manufacture of HYTREAT® DF in October, 2014, it has become the standard for Anti Agglomerate (AA) Low Dose Hydrate Inhibitors that customers in the Gulf of Mexico have come to rely on. Clariant is currently shipping HYTREAT DF products that enable the production of over 22 million BOE/Y. 

    An AA-LDHI is used to prevent hydrate formation in challenging production conditions, such as deepwater pipelines and subsea tie-backs. AA-LDHIs are specialty chemistries that provide significant cost benefits over thermodynamic hydrate inhibitor commodities, such as methanol or monoethylene glycol. The traditional solutions not only require higher dose rates, but can be hazardous and difficult to handle, transport and store.

    Customers choose Clariant Oil Services to help improve deepwater production and reduce operational 
    risk. DepFlux® (DF) certified products for deepwater applications are developed by Clariant experts in our Deepwater Centers of Excellence, strategically located in Houston, Rio de Janeiro, and Aberdeen. High specification DepFlux technologies ensure filterability, compatibility, thermal stability and pumpability, which are critical to preventing blockages in subsea umbilicals.

    Clariant Invests
    Because of changes that occurred in the chemical market in late 2013, the supply of proven Low Dose Hydrate Inhibitor (AA-LDHI) chemistries could have been disrupted. In line with Clariant’s long-term strategic commitment to support deepwater oil producers, the company assumed the manufacture and distribution of this proven AA-LDHI technology by implementing a number of quality management steps:

          1. 1. Secured the necessary patents and legal framework to ensure freedom to operate (FTO)
          2. 2. Worked with the current supplier to build enough inventories as safety stock –  a prudent move during ramp-up at the new manufacturing site
          3. 3. Transitioned manufacture and Quality Control to the in-house manufacturing process using Clariant Excellence, based upon Six Sigma methodologies
          4. 4. Worked with existing AA-LDHI consumers to ensure a smooth and risk-free transition 
    Once Clariant Excellence was applied, a significant investment was made toward R&D, equipment and manpower to ensure that quality was maintained and low process variability was achieved. 

    Broussard Opening Clariant Broussard, Louisiana facility

    Commercial trials began in October 2014, and Clariant segregated individual batches that would be sent to individual customers and conducted extensive quality control and performance testing at the plant, and in many cases, conducted additional testing offshore at the point of use. To ensure seamless distribution in its Gulf of Mexico region, Clariant purchased a warehousing site in Broussard, Louisiana. The Broussard facility, which supports onshore, offshore and deepwater, includes a 2,000 sq. ft. analytical laboratory, 1,800 sq. ft. quality control laboratory, and 400,000 gallons of total chemical storage.

    Clariant Shifts Market from Scale Removal to Scale Prevention
    Innovative SCALETREAT FeS inhibits iron sulfide scale at low, continuous doses

    Oil well producers are all-too-familiar with the flow assurance challenges associated with iron sulfide (FeS) scale build-up. Multiple system components, including the Induced Static Flotation (ISF) storage tanks, filter screens, and injection systems, can be affected by scale deposition and the resultant damage. This build-up can limit production, increase operating costs, contribute to equipment failure and decrease pumping rates.

    Until recently, traditional methods to address iron sulfide formations included allowing the scale to build up and then remove it with chelating agents, such as tetrakis hydroxymethyl phosphonium sulfate (THPS), with dosage rates comparable to the amount of scale present. Producers also employ acid cleaning tactics, but these require the equipment to be taken offline and typically led to hydrogen sulfide generation and subsequent system corrosion.

    “Iron sulfide scale formation is a significant and expensive challenge for oil and gas producers,” says Dr. Jonathan Wylde, global head of innovation for Clariant Oil Services. “It can lead to well failure and costly equipment repairs, resulting in lost revenue. In the past, chemical treatment alternatives required high doses of expensive chemistry to remove the scale. The industry simply could not afford to continue with the status-quo practice of scale build-up and removal.”

    Paradigm Shift
    Clariant Oil Services partnered with a oil well producer operating in one of the most successful mature oil production fields in the United States, to develop a more effective and economic solution for Iron Sulfide scale. The complex field included production originating from multiple zones and thousands of wells.

    The common problem experienced at the oil field: a high occurrence of iron sulfide scale formation. The specific partnership mission: develop a new high-performance scale inhibitor that shifts industry standard practice for resolving iron sulfide issues to scale prevention versus removal.

    The focus of the field trial was centered on one particular water injection system operated by the producer. This target system was riddled with dense iron sulfide deposition throughout the water treatment plant, which caused production interruptions and uncertainty that the production water was going where it was needed.

    Two forms of FeS-remediation methods were employed by the producer. “One included a THPS chelating agent dosed on the basis of stoichiometry equivalent to the amount of scale present,” explains Cyril Okocha, Ph.D., scale specialist, global innovation for Clariant Oil Services. “Acid cleaning was also employed, but this led to H2S generation and system corrosion. Both practices resulted in loss of production and equipment downtime.”

    Pulling from vast experience in developing best-in-class chemistry, Clariant Oil Services’ scientists started their research on developing a true scale inhibitor, building on a known foundation of copolymer chemistries. Laboratory tests, conducted in a purely aqueous media, showed three copolymer blends worked well at inhibiting iron sulfide accumulation.

    However, it is known throughout the industry that lab and field results do not always align. “The true test of a product’s efficacy rests on how it performs in the field,” mentions Scot Bodnar, head of flow assurance global innovation for Clariant Oil Services.

    Field Value Established
    Scientists first set out to devise a way to properly test and log the amount of iron sulfide deposition. They began by setting up a sidestream device with a turbine flow meter and chemical injection point on one of the FWKO vessels.

    “We decided the best approach was to use a two-electrode Linear Polarization Resistivity (LPR) probe positioned at the center of the sidestream to allow us to study the direct proportional relationship between iron sulfide scale thickness and electrical signal on the electrodes,” adds Bodnar. This gave the scientists an online, inline and real-time method of determining iron sulfide formation.

    Field trials began by establishing a blank baseline rate using no chemicals, and, within two weeks, deposition of 2 to 3 mm was observed on the LPR electrode. “We were amazed at how quickly the scale formed,” says Wylde. “At this rate, complete system blockage would have occurred in less than three months.” Iron sulfide dominated the scale composition, which also damaged the electrode.

    An inhibition baseline was established using the industry standard THPS chemistry used in the region. On clean electrodes, a dosage of 50 ppm was enough to show no deposit build-up. “However, field systems are pre-fouled with iron sulfide deposits, and the injection rate to halt further deposits on such systems was double that dosage,” comments Okocha.

    As trials progressed to the three different, lab-proven Clariant propriety copolymers, scientists documented performance field results much different than the lab findings. So they reformulated and optimized the chemistry using two new components. “This is precisely why we conduct field trials as part of our optimization process, so we get the right product that performs as needed for the customer in the field,” says Wylde.

    The new two-copolymer formulation, SCALETREAT FeS 13805, went through extensive field study. The results showed that it outperformed all of the other chemistries tested during the trails, including the benchmark THPS product. At half the dosage of the next best alternative, SCALETREAT FeS 13805 provided true iron sulfide scale inhibition, as the inline LPR electrodes showed no build-up or damage.

    Injected at threshold levels, the patented high-performance SCALETREAT FeS 13805 scale inhibitor offers a paradigm shift for the industry to scale inhibition, rather than the standard practice of scale deposition and removal.

    “Our innovative SCALETREAT FeS 13805 requires significantly less product dosage than current alternatives on the market, and continuous application of the product allows companies to maximize oil production and lower operating costs,” concludes Wylde. “Our cost-effective method for continuous control of iron sulfide promises to keep wells producing for longer periods between remediation and at higher rates, so producers can realize more profit potential.”

    Clariant Innovation Averts Well Shut-In

    HYTREAT® DF 12851A inhibits hydrate and reduces methanol concentration by 98%

    Subsea tiebacks (SSTB) are critical tools used in the production of oil and gas to exploit reservoirs once deemed economically unfeasible for exploration. By connecting new reservoirs to existing production facilities, tiebacks allow companies to produce more oil and gas at a lower cost. The bottom line – they help to maximize the life of existing production infrastructure, so companies can be more profitable.

    However, SSTBs come with their own set of unique challenges. Often requiring lines running for miles to tie into an existing facility in very deep water, flowline blockages are a great concern, especially when it comes to deepwater and Ultra Deepwater oil production. “Pipeline blockages can lead to shutdowns and great expense through lost production and line clearing,” explains Sam Pruett, US Business Line Director for Clariant Oil Services.

    Natural gas hydrates are a primary culprit leading to pressure spikes  and/or blockages in flowlines and pipelines.  These naturally occurring hydrates form together to impede the flow of natural gas and oil.  Due to the potential problems caused by hydrates, operators go to great lengths to stop this agglomeration. “One traditional method many companies use to stop hydrate agglomeration is injecting high amounts of methanol into the line,” adds Chris, “but this does not work well in all applications.”

    2,000 ppm Concentration

    At times, controlling one problem in oil production leads to another challenge that must be addressed. The Woodlands, Texas-based Clariant Oil Services recently worked with an oil producer in the Gulf of Mexico to develop a new, innovative anti-agglomerate chemistry to reduce the amount of methanol concentration in the oil phase, so a pipeline could continue to function not closed off (shut-in).

    The 11-mile-long (17.7-km) SSTB ran from a new well deposit back to its existing production facility in the Gulf. The line was responsible for producing 3,500 barrels of oil per day and another 3.8 million cubic feet of natural gas daily. 

    Keeping the line clear of blockages or pressure spikes required 1,500 gal/day (5,678 l/day) of methanol to remain outside of the hydrate risk region. While this high dosage of the chemical can work for controlling agglomeration in wet oil production, it can also result in significant methanol concentration spikes when working with a SSTB that produces less than 1% basic sediment & waste (BS&W).

    “In this case, the low water cut resulted in the methanol transferring into the oil phase,” says Scot Bodnar, Global Flow Assurance Manager for Clariant Oil Services. “The methanol concentration in the oil phase spiked to levels exceeding 2,000 ppm (using gas chromatography analysis), which is well over the pipeline specification of 50 ppm.”

    As a result, the pipeline company threatened to shut-in the well if the producer could not lower the methanol concentration in the oil to within spec limits. This is when the producer worked with Clariant Oil Services to develop another method for controlling hydrate agglomeration, reducing methanol concentration and increasing the oil quality.

    Innovative HYTREAT® DF 12851A Averts Shut-in

    Oil and gas producers operate in an extremely competitive environment, and; therefore, they are always looking for production cost advantages. Clariant Oil Services, with its continued investment in innovation, assists operators around the world in producing oil and gas more efficiently and recovering product that has a greater percentage of hydrocarbons, giving these producers a competitive edge.

    To quickly introduce new technology to the market, Clariant has adopted the philosophy of Better, Faster and More Efficient for all areas of operations in its oil and gas portfolio, from drilling and stimulation to production operations. In other words, Clariant Oil Services continues to optimize its products to perform better at more extreme conditions of temperature, pressure and salinity. Through the adoption of new experimental techniques such as high throughput experimentation (HTE), more commonly used in pharmaceutical labs, scientists formulate and test products faster. Finally, Clariant pushes to make chemicals work more efficiently for its customers.

    Efficiency gains achieved through innovative thinking and use of chemicals is evident in the development of Clariant Oil Services’ HYTREAT DF 12851A hydrate management and control product for the oil producer in the Gulf of Mexico. Whereas high dosages of methanol were required to control hydrate agglomeration, using the Clariant chemical solution resulted in a 97% drop in chemical use, a substantial savings for the producer and a significant advancement in sustainability efforts.

    HYTREAT DF 12851A provided a dual benefit in this application. First, the anti-agglomerate controlled hydrate formation to keep the flowline from pressure spikes and blockages. Equally as important, HYTREAT DF 12851A reduced methanol-in-crude concentration nearly 98%, from 2,000 ppm to 43 ppm, below the 50-ppm pipeline specifications to eliminate the need for any well shut-ins.

    Clariant Oil Services’ innovative thinking affected the bottom line for this Gulf oil producer as well. Traditional practice would have required installation of an expensive water wash system to mechanically reduce the methanol concentration levels in the oil. The innovative use of HYTREAT DF 12851A eliminated the need for the water wash system and production deferments, enabling the operator to realize even greater production figures valued in the millions of dollars per year.

    Better, faster and more efficient. Clariant’s continued investment in innovative technologies also allows its customers to produce oil and gas more profitably.

  • To say the oil and gas industry is competitive is an understatement. Operators are always looking for production cost advantages. In order to help operators produce oil and gas more efficiently and recover product greater percentage of hydrocarbons, Clariant Oil Services continues to invest in innovation that provides its customers with the competitive edge.

    The first quarter of 2015 has seen West Texas Intermediate oil prices drop to below, $50 per barrel, with the longer term outlook that prices will remain at this level at least until the end of this year with moderate recoveries in 2016. Resulting from this there has been a precipitous drop in rig count, far more so than when the oil price was low in previous years. Correspondingly, producers are cutting capital budgets for exploration and production by 30% and above.  A route cause behind the current oil price is a supply and demand imbalance, driven by record US shale oil production and OPEC nations maintaining high production rates. What is clear is that this pricing environment is leading to a new paradigm with a greater efficiencies resulting in lower costs to drill for, and produce oil, being sought. This, therefore, has far reaching consequences on the need to innovate and develop the next generation of technologies for the oil and gas industry.

    At Clariant, innovation is more than a word, it’s a culture. Clariant’s innovation process utilizes “Clariant Excellence,” a combination of Six Sigma and Lean Management principles. This ensures maximum operational efficiencies and the rapid progression of targeted market-based innovation projects that are in turn, supported by capital investment.

    A healthy innovation project portfolio balances short term goals and long term aspirations. Again, conventional thinking would conclude that a shift to a more short-term focus leads to a loss of quality and impact on project deliverables. Not so with Clariant Oil Services, as Clariant understands that its customers are in this game for the long-term.

    How is this being achieved at Clariant?

    Clariant has adopted the proven philosophy of: better, faster, and more efficient. This recipe is not unique to the oil and gas industry and has, over the years, been repeatedly proven in many industries. For Clariant, this methodology is applied to all areas of operations in the oil and gas portfolio, whether it’s in drilling, stimulation or production operations. Obvious examples of how this philosophy benefits customers in the field include the operation of production separators using Clariant demulsifiers.  Removing water from the oil more quickly with a lower residence time provides for lower base sediments and water, and for a lower operating cost versus the production returns.

    The value comes from the attention to detail. 

    • Clariant optimizes its products to perform better at more extreme conditions of temperature, pressure and salinity. Clariant R&D has recently produced novel surfactants that have been patented for use in enhanced oil recovery (EOR) processes. Traditional chemistry fails to perform at extremes of temperature and salinity. This novel chemistry offers a unique resilience in challenging conditions and allows the molecules to maintain structural integrity and surfactant performance. More efficient oil production results from better enhanced oil recovery performance – an attractive value proposition for Clariant’s customers.

       

    • Through adoption of new experimental techniques, Clariant is innovating faster than ever before. Clariant has adopted high throughput experimentation (HTE) in order to formulate and test products more rapidly. As an example, Clariant has recently used HTE to innovate surfactant-based products to improve oilfield stimulation operations. Robotic HTE formulation devices were used to identify the highest efficiency synergies of sustainable and environmentally-acceptable surfactant chemistries. This technology, first commercially exploited in the pharmaceutical industry, is used to formulate hundreds of samples in a matter of hours. Samples were passed from the formulation stage to a robotic optical measurement stage to determine microemulsion stability. From here, the samples were passed to a surface and interfacial tension measurement module, which is a fast screening test that determines the most potentially impactful chemistries and combinations of chemistries. In just six months, an environmentally-acceptable sugar-based surfactant microemulsion based product, HOSTAFRAC® SF, was developed, patented and applied in the oilfield to increase reservoir conductivity, increasing production for oil and gas operators. Clariant’s customers benefited from this innovation months or even years before it would have been created using processes that are typical in the industry.

    • Clariant is constantly working to make chemicals more efficiently for the customer. One example is the recent innovation of SCALETREAT FeS. This game changing technology enables control of iron sulfide (FeS) scale in mature (and marginal) produced water handling systems. Typical methods of control involve the use of chelating agents that ‘grab’ iron in the produced water and lock it away, preventing the formation of FeS. Clariant scientists reviewed the chemistries that were being used and asked “how can we produce this more efficiently for our customers?” The result was the new SCALETREAT FeS product, which adds a novel booster to an existing technology, reducing customers’ overall FeS scale control spend by over 30%.

      This new chemistry has been proven in the field at a major U.S. operator by preventing the formation of FeS in processing vessels, produced water filter systems and, most importantly, scale deposition in injector wells. Lower injection well failure rates resulted in an increase in overall water injection volume and a more efficient water sweep pattern in the reservoir. This sweep efficiency led to increased crude oil production. This new way of thinking took a commonly used chemistry and made it perform more efficiently!
