Innovative solutions for
UNCONVENTIONAL RESOURCESIncreased world energy consumption requires innovative solutions for the extraction of oil and gas. Especially unconventional resources need advanced techniques and know-how, while complying with domestic and environmental regulations. Clariant has developed the HOSTAFRAC™ SF product line to make hydraulic fracturing more sustainable and efficient.
RESISTANCE ON THE WAY IN AS WELL AS OUT
Organic deposits that are located between the reservoir rock grains can limit the spreading of water-based fracturing fluid into the rock formation. The effect can be enhanced by the formation of oil and water emulsion. During the so-called preflush, a smaller amount of water mixed with special additives is injected into the ground to prevent this. During flowback, the previously built-up high pressure is dissipated by backflowing a mixture of fluids, including the injected fracturing fluid, to the surface. The latter often becomes trapped in small capillaries inside the porous rock, preventing a maximum flow of oil and gas. This is caused by surface tension and adhesion forces working inside the small inter-granular rock pore spaces, often exacerbated by the gelling agents used in common fracturing fluids.
INNOVATIVE, SUSTAINABLE AND EFFICIENT
Preflush additive HOSTAFRAC™ SF is far less dangerous to plants and animals than common alternatives, biodegrades more quickly, and cannot bioaccumulate.
The flowback aid HOSTAFRAC™ SF is based on renewable sourced fats and sugar.
HIGHER FLOWBACKOF WATER
With HOSTAFRAC™ SF, up to
87% of the fracturing fluid used
can be recovered.
Compared to the use of common
preflush additives to prevent
emulsion formation, an increase
in production of more than
40% could be realized with
