HOUSTON, Mar. 8
– MedcoEnergi plans to install a downhole pump and zone isolation packer to dewater two coal seams at the CBM-SE-02 well at the Sekayu coalbed methane exploration project in South Sumatra, Indonesia.

CBM Asia Development Corp., Vancouver, said its partner Medco will dewater the Palembang B & C and Pangadang A coal seams to provide data on deep-radius reservoir permeability and water composition.

Medco also has contracted Weatherford International to conduct gas saturation testing. Later in March, Medco plans to begin coring the coal section for gas content and permeability testing in the three other CBM test wells in the deeper portion of the Sekayu project, CBM Asia said.

The CBM-SE-02 well has provided data on coal seam thickness and permeability, while the upcoming coring of the CBM-SE-01, -03 & -04 wells will help further define CBM resources on the block, providing critical input in support of CBM Asia’s planned NI 51-101 resource estimate.
