The Effect of Drilling Fluid on Coal's GasWater TwoPhase ... Hindawi

In the process of coal bed methane (CBM) production, the output of CBM is mainly related to the relative permeability of gas and water in coal seams. However, during the drilling process, the invasion of drilling fluid into CBM reservoirs changes the wettability, which may cause the gas and water's redistribution through the pores and cracks, further changing their twophase seepage ...

Coal Geology. Coal is a combustible sedimentary rock formed from ancient vegetation which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time period. This process is commonly called 'coalification'. Coal occurs as layers or seams, ranging in ...

Coring ( diamond drilling) is another way of collecting information about a potential coal resource. The drill rig is equipped with a hollow tube, and as the drill pushes the rods into the ground, a cylindrical piece of the rock is pushed into the hollow tube. These samples are usually the length of a drill rod, which is 6 meters.
