Eliminating formation damage, reducing rig timo

摘要

Baker Oil Tools developed a new tech-nology for completing wells in unconsolidated formations. The technology and technique is installing a liner hanger and sand control mechanism in a single trip to eliminate explosive perforation charges and associated formation damage risk. The BOT personnel can run production liner, flow conduit, primary cementing, and sand control tools in a single trip resulting in cost reduction. A Joint Investment Project (JIP) that included three major operators, a large service provider, and a small technology company, with the help of a grant from the Department of Energy, developed this new technology. Formation damage caused by perforating is one of the highest risks in well completions. Common types of damage that can occur inside the perforation tunnel are fractured and compacted zones, perforation gun debris, and broken formation blockages. Reducing or eliminating initial perforation damage results in a more productive well over its lifetime. BOT's new completion method eliminates gravel packing and minimizes intervention in completion operations, saving substantial rig time. It also simplifies operation logistics, especially in remote or offshore environments.
