Schlumberger released the GeoTesting geology-based well test design and interpretation services at the 2016 SPE Annual Technical Conference and Exhibition.
GeoTesting services, built in the Petrel exploration and production software platform, integrates geological and geophysical models with dynamic well test data in a shared earth model.
“GeoTesting services bring a new level of certainty to reservoir characterization with optimized well test designs that validate and calibrate reservoir models using dynamic measurements,” said Wallace Pescarini, president, Testing Services, Schlumberger. “With high-quality data and analysis representative of the reservoir, customers can vastly improve production forecasting, determine reservoir connectivity and identify sweet spots.”
The Petrel GeoTesting plug-in features Global Sensitivity Analysis designed for targeting geological features of interest and incorporating uncertainty in the geological model during well test design and execution.
New grid-based inversion technology automatically calibrates reservoir models with dynamic well test data for direct integration into the reservoir model. In addition, the naturally fractured reservoir pressure transient simulator provides new insight into the complex behavior of transients and the matrix–fracture interaction.
Operating in the Norwegian Barents Sea, OMV used GeoTesting services to characterize a geologically complex reservoir, which presented many challenges including proximity to nearby faults, oil/water contact, uncertainty in fault conductivities, permeability and anisotropy. Success was achieved using GeoTesting services to optimize the well test design and calibrate the reservoir model with dynamic well test data—establishing confidence in the final model and confirming reservoir connectivity.
