The "C" in CBM stands for coal and that is why Petro Logic's geologists all have training and experience in coal geology. Our wellsite team is well-equipped and experienced to supervise coring or cuttings collection and to conduct all the requirements of desorption testing including:
optimization of core recovery,
In addition to assessing the coal and gas resource, core testing offers insight into the reservoir quality. Petro Logic's geologists provide:
These parameters have been shown to have established relationships with coal permeability and producibility. We recommend detailed visual description of all coal cores.
Petro-Logic's wellsite protocols for both core and cuttings provide data compliant with the requirements of Alberta ERCB for "CBM Control Well" status. The ERCB has established regulations requiring the validation of "CBM Desorption Control Wells" prior to approval of CBM production. A "control well" is a well in which the gas desorption data and associated analyses have been approved by ERCB. For any operator to produce CBM the ERCB requires:
A valid descrption test may be from core or from cuttings if the cuttings data can be scientifically calibrated to an approved core well within an offsetting township.
Petro-Logic's experienced CBM geologists can prepare applications for control well status for cored wells and for cuttings wells by meeting the ERCB's requirements of scientific calibration to an approved and cored CBM control well.
All public gas content and coal quality data can be found on the CBMWellInfo.com website. This is a web-hosted , map-based compilation of data derived from the desorption reports submitted to ERCB by CBM exploration companies.
