Economic evaluation of directional drilling for methane drainage from coalbeds. [Avondale, Md.]: U.S. Dept. of the Interior, Bureau of Mines, (OCoLC) The coalbed methane (CBM) development activities in China are concentrated in the regions with low-permeability coal reservoirs.

There are two kinds of drilling technologies: one is the conventional vertical well technology, the other is multi-branch horizontal well by: 7. Economic evaluation of directional drilling for methane drainage from coalbeds / By G.

Always update books hourly, if not looking, search in the book. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized.

Both economic and environmental concerns have sparked this impetus to capture coalbed methane. @article{osti_, title = {Drilling a horizontal coalbed methane drainage system from a directional surface borehole}, author = {Oyler, D.C.

and Diamond, W.P.}, abstractNote = {Three long horizontal holes were drilled from a directionally drilled surface hole at the Emerald Mine near Waynesburg, Penn. The purpose was to adapt the technique of directional drilling for use in draining.

A Review of Horizontal Drilling and Completion Techniques for Recovery of Coalbed Methane The US Bureau of Mines has demonstrated that methane drainage by horizontal and directional boreholes is a safe and effective method of removing methane in advance of mining and of controlling methane emissions during mining.

Coalbeds are much Cited by: Introduction. In-mine horizontal methane drainage boreholes have been proven very effective in reducing methane emissions to safe levels in advance of mining (Kravits et al., AprilDuBois et al.,Thakur and Poundstone, June ).However, the underground access required to drill in-mine horizontal boreholes limits their ability to degasify beyond the perimeter of the current Author: Stephen Kravits, Gary DuBois.

Coal Bed Methane: From Prospect to Pipeline is the proceedings of the 25th anniversary of the North American Coal Bed Methane provides the latest advancements in the production of coal bed methane covering a variety of topics, from exploration to gas processing, for commercial utilization.

The Bureau of Mines estimated the economic feasibility of investing in a directional hole methane drainage project in the Pittsburgh coalbed for 5 yr in advance of mining.

Baker. Coalbed methane (CBM) is an unconven-tional source of natural gas produced from coal seams. In recent years, it has gained a lot of attention and is being developed as a significant energy source.

Gas outburst disasters are becoming more serious as the underground coal mines become deeper in China, and a thick zone of deformed coal provides conditions favorable to coal and gas outbursts. The Daning coal mine’s main mining seam is the No.

3 coal seam with coal and gas outburst hazard, which often contains two normal coal sub-layers and one deformed by: Abstract. Previous economic studies of the recovery and utilization of methane from coalbeds using vertical wells were based on drainage in advance of mining where a single seam is drained with well spacing designed for rapid by: 1.

Coalbed Methane (CBM) is a high-quality unconventional energy resource. The successful development and utilization of a CBM resource needs to consider technical feasibility and economic viability. These factors are also necessary for the improvement of production safety in coal mines, reducing carbon emission, and optimizing energy structure.

The potential profitability of a horizontal borehole drilling program for recovering methane gas in an Alabama coalbed for 6 yr in advance of mining is estimated in this Bureau of Mines report. A cash flow analysis based on estimated capital investments, annual operating costs, and the selling price of methane gas was used to determine the net.The principal objective of this pre-feasibility study is to assess the technical and economic viability of methane drainage utilizing longhole directional drilling at the Amasra Hard Coal Mine, and using this gas to produce electricity or compressed natural gas (CNG).
