Well sample/borehole diagnostic methods for tight black shales. Final report, October 1985-August 1988
This study was designed to aid industry in the exploitation of the shale gas resource, and consisted of two complementary parts. (1) A well-site technique was developed to evaluate the production potential of the Devonian shale and other low-permeability formations. The instruments measure the concentration and composition of free hydrocarbons and the source potential of cuttings/core samples. Examples of the use of the technology to determine the presence of free gas or oil, identify hydrocarbon reservoirs, and locate potentially permeable zones are presented in the report. The well-site geochemistry technique complements the GRI well log interpretation work as a formation evaluation tool for the Devonian shales. (2) A regional geochemical framework of the shale formations was completed. The framework incorporates the data from the 15 GRI study wells analyzed by wellsite geochemistry as well as data from an additional 48 preexisting wells. The geochemical framework facilitates understanding of the occurrence of hydrocarbons in the Devonian shale sequence and calculation of the amounts of hydrocarbons generated within key shale formations.
