SCHLUMBERGER RESERVOIR LABORATORY Salt Lake City, Utah, USA The Schlumberger Reservoir Laboratory in Salt Lake City integrates rock mechanics, core analysis, and petrology expertise to provide customers with measurable insight into their reservoirs. The 85,000-ft2 facility houses the Geomechanics Center of Excellence, which includes equipment that can perform large-block polyaxial stress fracture tests and large-scale drilling simulation. Each test is carefully designed and executed to meet a common goal—enabling customers to optimize drilling and completion operations with reduced risk. Specializing in unconventional projects, the Salt Lake City laboratory globally supports characterization projects by delivering end-to-end services—from field core acquisition to integrating in-house analytical measurements into customized workflows. Schlumberger TerraTek TRA* tight rock analysis service provides a comprehensive dataset, and TerraTek HRA* heterogeneous rock analysis service integrates the obtained data with log data to deliver a quantitative, unbiased rock classification that can be systematically propagated from one field to the next. Additionally, petrographic services are incorporated into the workflow, ensuring that rock texture and fabric are accounted for in the comprehensive reservoir characterization. WELLSITE SERVICES AND CORE HANDLING Reservoir laboratory staff focuses on the details of each measurement while adhering to rigorous quality-control measures, which assures that customers receive accurate, actionable, repeatable results. Whether optimizing single-well operations or extending knowledge across the entire field, Schlumberger Reservoir Laboratories enable betterinformed decisions across the entire E&P life cycle. The Schlumberger Reservoir Laboratory in Salt Lake City provides detailed and individual tests that are unmatched in quality.
