GST-WellDog operates the world's premier coalbed reservoir simulation laboratory. The primary work of that laboratory is directed toward exacting calibration of the company's tools and sensors. However, it also provides us with the opportunity to explore the cutting edge of coalbed methane reservoir geophysics and geochemistry.

GST-WellDog's simulation cells can be analyzed using a variety of sophisticated laboratory instruments, including video microscopy, in order to capture the physicochemical processes involved in depressurizing and producing gas from a coal seam. Examples of some of those processes are shown in the below videos.


Big George subbituminous coal, equilibrated at 320 psi methane CDP and then 1865 psi hydrostatic head.

Dewatered until substantial gas production had occurred. Left graph shows total reservoir pressure and CDP measured during dewatering experiment. Right video micrograph shows coal/water interface with field of view of 7.2 mm wide.

 

> Reduce your water-gas production ratio and related costs.

> Increase your multizone production success by completing just the producible seams.

> Measure the drawdown required to produce your gas.
