FLC2000^TM is Impact Fluid Solution's key additive to engineer ultra-low invasion drilling fluids, completion fluids and work-over fluids. To date, FLC2000 has been used successfully in over 700 wells world-wide. Its use in both water-based and oil or synthetic based systems continues to increase due to the high success rates achieved. Candidate wells for the use of FLC2000 are carefully selected after rigorous technical evaluation to ensure that the application is fit for purpose. Related technology is also used to produce ultra-low invasion cementing spacers.

FLC2000 greatly reduces fluid invasion into matrix permeability and micro-fractures. It is a blend of modified cellulosic polymers and surface functionalized organic solids with additives that enhance performance at high temperatures and in the presence of sour gas. The molecular weights of the polymer components are low to allow easy mixing and minimize impact on fluid viscosity.

By forming a very low permeability barrier over pores and micro-fractures, FLC2000 limits transmission of the well-bore pressure to the pore fluid. This is instrumental in preventing formation fracturing by preventing fracture propagation and effectively raises the fracture initiation pressure. Hence, these fluids are well suited to deepwater applications and in depleted, poorly consolidated formations.

In reservoir applications, low formation damage is clearly of paramount importance. Results obtained in third party laboratories have shown that properly formulated FLC2000 fluids typically give return permeabilities in excess of 90% and show low flow initiation pressures. Excellent results have been obtained for solids-free fluids as well as weighted systems.
