Coal Bed Methane $3,000.00

Successful Case Study: This well with complex lithology - coal measure strata was processed by our technology to determine the interval as a high productive oil & gas pay in fractured coal seam and fractured zones of shaly sand. The well was tested with high production in 02/19/2003.

The primary energy source of natural gas is a substance called methane (CH4). Coal bed methane (CBM) is simply methane found in coal seams. It is produced by non-traditional means, and therefore, while it is sold and used the same as traditional natural gas, its production is very different. CBM is generated either from a biological process as a result of microbial action or from a thermal process as a result of increasing heat with depth of the coal. Often a coal seam is saturated with water, with methane is held in the coal by water pressure. Currently, natural gas from coal beds accounts for approximately 7% of total natural gas production in the United States.
According to the CBM Association of Alabama, 13% of the land in the lower 48 United States has some coal under it, and some of this coal contains methane - either in the form we know as traditional natural gas or as CBM. According to the United States Geological Survey, the Rocky Mountain Region has extensive coal deposits bearing an estimated 30-58 trillion cubic feet (TCF) of recoverable CBM. While impressive, this represents only one third of the total 184 TCF of natural gas in the Rocky Mountain region (Decker, 2001).
Within the Rocky Mountain Region, untapped sources of CBM exist in the Powder River Basin of Wyoming and Montana, the Greater Green River Basin of Wyoming, Colorado, and Utah, the Uinta-Piceance Basin of Colorado and Utah, and the Raton and San Juan Basins of Colorado and New Mexico. An estimated 24 TCF of recoverable CBM resources may lie below the Powder River basin of Montana and Wyoming (Decker, 2001).

What Makes Our Process More Accurate

LogDigi technology completely adopts relative concepts and rebuilds a strict lithologic conductive equation. LogDigi technology is significantly improved well log analysis technology and different from current well-logging interpretation methods that use absolute concepts.

Traditional technologies are all based on an approximate value in the designing of well-logging equipment, result measurements, data collection and data processing. When facing extremely complex lithology, it is necessary to design models in each area based on changes in objective conditions. Traditional technology does not adapt based on changes of objective conditions. Traditional technology is often affected by different lithological, regional, and well conditions. Traditional technology cannot accurately locate oil and gas zones with complex lithology.

LogDigi technology has changed the current technology model of evaluating quantitative oil/gas formations. This technology is a breakthrough in well-logging technology, and an innovative method for the discovery of new oil and gas zones. LogDigi technology can automatically remove the influences of lithology variations in different areas and different depths. It can also compensate complex conditions, such as influences of deep intrusion of mud filtrate in drilling with saline mud. LogDigi method also evaluates the influences of oil layer flood out and automatically finds out whether or not the parameters are accordant with actual situations. This allows us to locate oil and gas zones 90% and greater. log evalution for porosity, saturation, effective thickness of reservoir beds. This plot is one of the successful samples.  Contact us for detail.

90% old oil wells do not have Nuclear and Sonic logging. For many oil companies, in order to re-exame their oil fields, they have to sent down sophisticated nuclear, and acoustic tools on a wire-line for the well. It costs them a lot to do that.

  • We re-evalute your oil fields with your existing logs. We do not need "many times costly core sample taken from the well", and "sophisticated nuclear, and acoustic tools are sent down the well on a wire-line". What we need just gamma ray (or SP),and resistivity. We can match your budget to re-evaluate your oil fields.
  • We determine the fluid and pressure distributions throughout the reservoir, the natural energy sources available, and the methods most useful in recovering the maximum amount of oil or gas from the reservoir.
  • We analyze, interpret, and optimize the performance of individual wells. We decides if it is economically feasible to make the investment needed to produce the well. If it is, the production engineer is given the tasks to determined how to bring this valuable fluid to the surface.
  • We analyze data to locate drilling sites where oil and gas may have accumulated in commercial quantities.
