Depleted Sands

Turbo­‐Chem produced the most efficient means of solving the wellbore stability issues of sealing depleted sands and micro-­‐fractures. We dedicated endless hours of research and top‐of­‐the­‐line technology to creating Premium Seal’s® and Turbo­‐ Phalt™. Premium Seal® is superior to other products on the market, because its optimum particle size distribution allows the sealing of micro­‐fractures, sands and depleted formations. Unlike generic “cellulose fibers” on the market that are pulverized and reduced to an unoriginal form, Premium Seal® is composed of specially sized, custom cotton linters. Turbo-Phalt™ is shale stabilizing Gilsonite and resin blend. Its highly effective in HTHP water loss reduction results in a tough lubricating wall cake and reduces differential sticking tendencies in low­‐pressure sands.

There are two types of specialty products which have proven effective in preventing “differential sticking” while drilling depleted sands, namely, Gilsonite and Cellulose Fibers. In severe conditions , one or both products can be maintained in the mud system. Although, both products improve the plugging efficiency of drilling fluids, they function in a different manor.” SPE/IADC Paper 21913 “Successfully Drilling Severely Depleted Sands”

Turbo-Chem can increase the integrity of the well bore, by what we call a “snowshoe” effect. The fibers and resin in the SYN-Seal® will form an integrated thin wall cake, which will spread the pressure load across a broader area, thereby increasing the well bore integrity. The pressure load is simply broadened across a wider area creating increased support, effectively increasing the integrity in that area to a higher stress level. This is what the SYN-Seal® is creating through an integrated filter cake, spreading the load across the fracture(s) effectively increasing the well bore integrity, in some cases by several points. By preventing losses the producing formations are also protected from not only fluid, but solids invasion too, which also a major concern, especially in the lower pressured, partially depleted sands.
