Lost circulation challenges
When drilling the surface sections of wells through a vugular, naturally fractured formation, a Middle East operator frequently experienced total circulation losses. These losses resulted in stuck pipe, high costs for lost drilling fluid, challenges related to cuttings and returns handling at surface, and well control risks because of a shallow flowing aquifer.
Conventional lost circulation material failures
Conventional lost circulation material (LCM) minimized losses while drilling wells at low inclinations, but the conventional materials were unable to stop or slow the losses when drilling
at high inclinations.
Cementing solution for plugging voids
ThixoCRETE solution combines lightweight high-performance trimodal cement and a thixotropic additive to rapidly deliver high gel strength and compressive strength. Its optimized solids content and plugging efficiency rapidly plugs large voids and fractures so that drilling can continue.
