Case Study: Hess Corporation saves 3 days offshore Malaysia with SLB SpectraSphere Fluid Mapping-While-Drilling Service

Hess Corporation reduces risk and optimizes logging program by analyzing fluid, gas, and pressure data in highly deviated wellbore

Hess Corporation worked with SLB to address the challenge of acquiring formation fluid samples and pressure measurements in a highly deviated offshore Malaysia wellbore that crossed pressure-depleted zones and carried a risk of differential sticking. The company needed better reservoir-fluid data to support field development, completion, and production planning, and used SLB’s SpectraSphere fluid mapping-while-drilling service.

SLB deployed SpectraSphere to collect reservoir-representative fluid and gas samples plus pressure data in one run, with real-time monitoring of fluid cleanup and downhole conditions. Hess obtained 4 fluid samples, 2 gas samples, and 21 pressure measurements with less than 1% contamination, completed sampling in 2 hours per station, and avoided differential sticking; the work saved 3 days by eliminating additional formation testing in two other wells.
