STUDY ON UPGRADING OF CONVENTIONAL CEMENT FOR ZONAL ISOLATION IN COALBED METHANE (CBM)WELLS BY USING FOAMEDCEMENT

Cementing gas wells in coalbed methane (CBM) formations can present a cementcirculation challenge because the coal formations tend to have low fracture gradients and break down under the hydrostatic pressure of the cement column. The use of conventional lightweight cement slurries and/or foam ceme...
