Case Study: a large oil drilling service provider saves USD 267,000 and resumes drilling with SLB's Losseal Natural Fracture treatment

Losseal Natural Fracture Treatment Saves Operator USD 267,000 After Total WBM Losses Pakistan

SLB worked with a large oil drilling service provider in Pakistan that was struggling with severe lost circulation while drilling an 8½-in open hole section through naturally fractured formation. After partial losses escalated to total mud losses and a required increase in mud weight, the operator could not continue drilling safely or cement the liner without risking further incidents.

SLB used Lost Circulation Control Advisor software to design a Losseal Natural Fracture treatment, a composite pill of fibers and solids that strengthened the formation and controlled losses with a single squeeze pill. The solution enabled drilling to continue, allowed the 7¾-in liner to be cemented as planned, and delivered an estimated USD 267,000 in savings, including about USD 57,000 from reduced mud losses and USD 210,000 from avoiding remedial cementing.
