WebApr 14, 2015 · Today Wyoming’s coal-bed methane gas play in the Powder River Basin is a bust. Few of the 24,000 wells drilled during the heyday of the 2000s produce much gas, … WebNov 1, 2003 · For a coalbed methane well, the tightness and the reactive gas-rock nature deprive the gas of the needed pore spaces and the time for the material-balance to take place. Consequently, a P/Z plot constructed based on the observed apparent pressure-production-time data bends to the right, similar to a P/Z plot of a conventional gas well … shot from behind the backboard
Horizontal Coalbed Methane Wells Drilled from Surface
This technique is a variation of the preceding technique. In this technique, a hole is drilled to the top of the main target coal seam and casing is run and cemented as before. After underreaming, a bridge plug is set above the primary completion interval, and additional coal seams are completed according to … See more Factors to be considered in the selection of the drilling and completion technique include 1. Reservoir thickness 2. Coal cleat/fracture … See more The major steps for this drilling and completion technique are 1. Drilling the production hole to the top of the coal seam 2. Running and … See more This technique is by far the most common technique for drilling and completing CBM fields, especially where multiple completable seams are encountered and many or most of them need to be hydraulically … See more This drilling and completion technique (Fig. 2)is similar to the vertical-well openhole single-seam underream completion in that a hole is drilled to the top of the coal seam, … See more WebCoalbed Methane Table 2: Operators of Coalbed Methane Wells, 2005 [PDF 22KB] Coalbed methane production and reserves.
