TMK starts drilling SL-2 CBM well in Mongolia
TMK Energy, formerly Tamaska Oil and Gas, has started drilling on the second well, Snow Leopard-2 (SL-2), of its maiden drilling programme within the Nariin Sukhait area of the Gurvantes XXXV coalbed methane (CBM) project in the South Gobi basin of Mongolia, it said on May 16.
SL-2 is planned to be drilled to a depth of approximately 600 m and is targeting the same coal formations intersected in the first well, Snow Leopard-1 (SL-1). The well will be cored, and any significant coalbeds intercepted will be sampled and subjected to the same gas desorption testing as was undertaken at SL-1 to provide data on gas content, saturation, and composition at this location. Further results on gas contents and permeability test data from SL-1 are expected to be available shortly, TMK said.
On completion of SL-2, a further two fully cored holes within the Nariin Sukhait area are planned to be drilled and tested over the next two or three months. The start of the pilot well programme remains on track in the second half of 2022, the company said.
Additionally, the data collected from the initial four-well drilling campaign is expected to enable the company to convert a portion of the independently certified 5.96 trillion ft3 gross prospective resource into a maiden contingent resource in the second half of 2022.
The Gurvantes project covers an area of 8,400 km2 and is situated around 20 km from the Chinese-Mongolian border and close to the northern China gas transmission and distribution network. TMK earlier this year completed the acquisition of Telmen Energy, which held a 100% interest in the Gurvantes XXXV project.
