Drilling Program Planning and Field Operations Protocols for Coalbed Methane and Shale Gas Reservoirs in Canada
This document is a guide to coalbed methane and shale gas drilling, including program planning, field operations practices and procedures that have been successful in the Western Canada Sedimentary Basin. The report outlines important considerations for planning a drilling program and contains procedures to develop these unique and challenging reservoirs. Successful procedures are discussed relating to wellsite operations, such as drilling practices, rig type, identifying core points, determining sample intervals, core handling techniques and sampling.
Summary:
This document is a guide to coalbed methane and shale gas drilling, including program planning, field operations practices and procedures that have been successful in the Western Canada Sedimentary Basin. In Canada, coalbed methane and gas shale reservoirs are virtually untapped and are still in the early stages of development. The report outlines important considerations for planning a drilling program and contains procedures to develop these unique and challenging reservoirs. Successful procedures are discussed relating to wellsite operations, such as drilling practices, rig type, identifying core points, determining sample intervals, core handling techniques and sampling. In addition, recommended suites of geophysical logs necessary for analyzing these unconventional reservoirs are discussed in detail. Selecting an appropriate geophysical logging suite is essential for maximizing well data, and specific considerations related to these reservoirs are covered. Recommendations and rationale regarding the types of laboratory analyses necessary for characterizing these dual source and reservoir rocks are given. Analyses of drill core and cuttings are discussed to maximize data critical to reservoir characterization. Procedures and criteria for handling and sampling are essential for a successful exploration program.
