If core recovery for a coal ply is less than 95%, then that section of the hole is redrilled to ensure a representative sample is taken. • Ply samples are checked for representativeness theoretical mass that is using a determined using analysed relative density, sample thickness and core diameter prior to composite definition. • Open hole chip recovery is assessed qualitatively by the rig ...
Coal fines migration exerts negative impacts on early water drainage of undersaturated coal seam gas (CSG) reservoirs. The complied migration process results in ineffective and inaccurate forecast of coal fines production. Hence, a robust modelling tool is required to include the mechanisms of fines migration and to predict their impacts on rock and production.
· This paper explains in detail the workflow, challenges such as depleted reservoirs, coal streaks, and nearby water contacts and operational execution for the successful redefined extension pack jobs. This new approach consists of a redefined Extension Pack / Frac Pack job with fine movement control resin and a redefined perforation strategy. Perforation strategy consists of limited .
· A novel technique for selectively coagulating and separating coal from dispersed mineral matter has been developed at ia Tech. The process, Selective Hydrophobic Coagulation (SHC), has been studied since 1986 under the sponsorship of the US Department of Energy (Contracts AC2286PC91221 and AC2290PC90174). The SHC process differs from oil agglomeration, shear or .

various coal mines. The new approach to questions of industrial hygiene is widely elaborated at the present time by means of socalled exposure tests. Instead of relying only on measurement of a noxious substance in air, the urine of an exposed subject is analyzed either for the noxious substance itself or for its metabolites. Provided that the substance or its metabolites appear in mine ...
