Finding oil and gas underground takes more than a drill rig. A 2020 Gulf Coast Western reviews highlight two technologies the Dallas company relies on: horizontal drilling and seismic surveys. The article presents the pairing as more cost effective and efficient than conventional exploration methods.

Turning the Wellbore Sideways

Horizontal drilling starts like a standard well. Crews drill straight down until they reach the reservoir, then gradually angle the bore until it runs parallel to the formation. Drilling continues horizontally to the desired length. This design increases contact between the wellbore and the deposit.

Hamilton reports that Gulf Coast Western prefers this method because it produces more gas than vertical drilling and causes less environmental harm. The technique also lets operators work around geographical features that would block a vertical well. The company reportedly cleans drill bits and other equipment with dry ice rather than water, cutting water use, and lays out its sites to limit ecological impact on surrounding land.

Reading the Earth With Seismic Waves

Seismic surveys come before the drill. These geophysical studies measure how the ground responds to seismic waves, revealing the elastic properties of buried materials and the structures that may hold petroleum or natural gas.

Three common types are outlined. Reflection surveys analyze waves that bounce off layers with different elastic properties. Refraction surveys rely on the fact that waves travel at different speeds through different rocks and soils; studying those velocities and arrival times can estimate the depth of layer boundaries, the bedrock surface, and the water table. Surface wave surveys estimate velocities at near-surface sites and work well in urban settings, since the amplitude of these waves decreases with depth.

Results are typically displayed as cross-sectional drawings, charts, or maps known as seismic profiles.

The company’s Louisiana holdings show how central this data is to its work. Through a subsidiary, Gulf Coast Western acquired proprietary rights to 100 square miles of 3D seismic data in Lafayette in 2016. The review credits CEO Matthew Fleeger with keeping the company efficient through difficult market conditions, in part by adopting these tools. Refer to this article for related information.
