Abstract
The industry is challenged to accurately determine the total hydrocarbon composition and saturations in both conventional and unconventional reservoirs. Several attempts in coring technology advances have been employed in the past with limited success. These attempts include methods to collect expelled pore space fluids and gases for further analysis. The attempts have resulted in technologies that provide limited core in terms of length and diameter, low recovery percentages, poor success ratios and complicated core processing. Pressure coring itself has been viewed as a solution but introduces inherent safety concerns by bringing high-pressure systems to the surface. The combination of poor reliability and safety risks has resulted in infrequent use of the various technologies and methods to analyze pore fluids and gases. A new tool has been developed to overcome the safety concerns, simplify core processing and provide the means for quantitative answers.
