The analysis and prediction of subsurface geohazards ahead of the drill bit and while drilling is an essential requirement for safe and cost-effective drilling operations. Geohazards analysis, which includes geopressure prediction and shallow marine hazards risk assessment, uses a highly integrated workflow that requires a high-level of integration and expertise in seismic analysis, log analysis and well performance analysis.
The prediction of pore pressure and fracture gradient ahead of the drill bit is one of the most critical tasks in planning a well. With deepwater well costs running upwards of 100M per well, this process can save the operator millions of dollars in avoiding a single well intervention or pressure event.
SIGMA³ offers its pressure prediction services as part of the planning process, and our world-class team works with the client's drilling engineers to help them understand the results of this process.
SIGMA³ experts have more than 100 years of combined experience in predicting pressures for well planning in some of the most complex basins in the world, including the prediction and modeling of reservoir pressures to assist in planning a robust casing and mud program for difficult wells.
We use our depth of expertise and global experience to provide our clients with robust pressure solutions that save them significant amounts of money and pressure-related downtime on their wells.
Understanding the unknown is crucial to safe drilling operations. SIGMA³ has assembled the finest team of shallow hazards experts in the industry, and we offer superior solutions in geopressure that will enhance your exploration efforts and dramatically reduce your drilling and completion costs.
