Seismic survey of coal bed methane scheme in Mongolia gets underway

Jade Gas Holdings is shooting a 2D seismic survey at the flagship Tavan Tolgoi coal bed methane Project (TTCBM) in the south Gobi region of Mongolia.

The survey will further augment the extensive data set that Jade has obtained through its exploration activities in the Red Lake area and beyond over the last few years, and incorporates learnings from a seismic program undertaken by a previous operator.

Local Mongolian seismic operator Geosignals is mobilising crew and equipment, including vibroseis units and wireless recording equipment, from Ulaanbaatar to the TTCBM project site.

The 19-line, 105 km survey includes two lines specifically following the planned trajectories of the upcoming lateral wells. The objective of the survey is to delineate the coal seams to assist with geosteering the forthcoming lateral wells in the target seams, maximising contact with the coal and derisking the wells by identifying potential geological hazards prior to drilling.

It is hoped that the survey will enable Jade to better visualise and understand the structural architecture of the entire Red Lake area, identifying areas that have undergone structural flex that may indicate areas of improved permeability.

Jades is also identifying potential zones of seam thickening where resource concentration will be higher and integrating the corehole drilling in the north of the area will extend field limits of the current 246 Bcf1 unrisked Gross 2C contingent resources.

Jade executive director, Joe Burke, said: ‘The data captured under this seismic program is an important step to assist our technical team as they continue planning for the upcoming pilot production drilling later this year.’
