Coalbed Methane Solutions

Coalbed methane (CBM) now represents almost 10% of US domestic gas production with commer-

cial production growing in Canada, Australia, and other countries. Schlumberger has been at the forefront of CBM extraction services since the industry was established, with one primary objective—getting our clients’ CBM play into optimal production quickly with the lowest overall production cost.

Integrated sOlutIOns

Schlumberger has developed solutions that use the best in CBM exploration, reservoir evaluation, and stimulation technology, as well as in completion and production operations.

TerraTek* Geomechanics Labora-tory Center of Excellence services analyze the gas content and sorptive capacity of the reservoir during exploration. We offer consulting services for analyzing CBM reservoirs and production performance. Our formation evaluation services provide a clear understanding of the reservoir.

Stimulation services deliver engineered fracturing solutions, while completion services design and install optimum dewatering facilities for sustained production.

We also assist CBM operators in the planning of field development specifically tailored for each play. This plan may include commercially innovative solutions that use shared risk business models.
