Case Study: Western Siberia Operating Company achieves accurate Arctic well testing with SLB PhaseTester and PhaseSampler

PhaseTester Portable Multiphase Well Testing Equipment Conquers Challenges of Arctic Well Testing

SLB worked with Western Siberia Operating Company to measure flow rates and collect fluid samples during a flow test of an exploration well in harsh Arctic conditions, where paraffin deposits in the tubing created difficult testing conditions. The company needed reliable well testing data and representative samples from the well.

SLB deployed PhaseTester portable multiphase well testing equipment, PhaseSampler multiphase sampling equipment, and Vx multiphase well testing technology to capture high-quality measurements and PVT-quality samples at line conditions. The solution helped Western Siberia Operating Company achieve all testing objectives, including estimating well productivity, reservoir porosity and permeability, and sampling fluids, with results confirmed by test tank fluid levels, downhole sample analysis, and pressure buildup interpretation.
