Computing Hydrocarbon Saturation in Laminated Reservoirs

Under the general designation of thinly bedded reservoirs, a large class of hydrocarbon bearing formations exhibit widely varying characteristics. The thickness of the laminations may be as little as few millimeters and as large as several centimeters. While laminated reservoirs are generally assumed to be made up of sand-shale sequences, many include carbonate layers or more complex lithology. In the case of thick laminations, formation evaluation...

Integrated Real-Time Geopressure, Earth Stress…

and Wellbore Stability Analysis for Deepwater Drilling Operations All too frequently deepwater drilling operations are hampered by formation fluid influx (kick), drilling fluid loss (hydraulic fracture) and wellbore instability due to shear failure. These events are estimated to cost the industry almost $8 billion every year, and this number has not decreased despite advances in pre-drill modeling. Indeed, a GOM operator study cited 44% of their...

What Can Deepwater Operators Do … (Part I of III)

to Help Improve Drilling Safety and Ensure Well Integrity? A recent report, “Effects of Water Depth Workshop”, published in March of 2011, was on a study coordinated by the Argonne National Lab (ANL) for the U.S. Bureau of Safety and Environmental Enforcement (BSEE) on the effects of water depth on offshore equipment and operations. This two-day workshop in November 2011 consisted of 6 committees comprised of...
