“Mudlogging Unconventional Gas Reservoirs”
Presented at the Unconventional Gas Technical Forum, Ministry of Energy, Mines and Petroleum Resources, Victoria, British Columbia, Canada on April 16, 2007. This paper compares the gas reserves in different conventional and unconventional reservoirs from a mudlogging perspective. A metric version of this presentation is available by contacting Automated Mudlogging Systems.
“Mudlogging Unconventional Reservoirs”
Presented at the Fifth Annual Shale Gas Symposium for the Strategic Research Institute on November 30, 2006 in Denver, Colorado. This paper discusses flushing before the bit due to overbalance, up hole zone contribution and “background” effects and methods to detect and correct these factors.
“Evaluating Tight Gas, Shale Gas and Coal Bed Methane Wells using Mudlogging Methods”
Presented at the Rocky Mountain Natural Gas 2006 Conference (COGA/RMAG) Program, Denver, Colorado, on August 7, 2006. This PowerPoint presentation discusses ways to present mudlogging data by converting mudlogging units to: SCF of gas per cubic foot of bulk reservoir volume; MCF of gas per acre foot; BCF or gas per section foot; Bulk Volume mudlogging gas and Gas Content
“Mudlogging Gas Content Results Compared to Production Performance”
Presented at the Society of Petroleum Engineers (SPE) Luncheon Program, Denver, Colorado, on December 17, 2003. This paper compares mudlogging gas content results to wells with production history greater than two years. Gas content from accepted isotherm data is also compared to the same wells. The cumulative production and estimated ultimate reserves are presented as if they were gas content in a volumetric reservoir. These “back” calculated production based gas contented data are then compared to mudlogging gas content and isotherm gas content. This demonstrates the predictive power of mudlogging gas content.
“Coal Bed Methane Gas Content Determined by Mudlogging Methods”
Presented at the Rocky Mountain Association of Geologist (RMAG-AAPG) Luncheon Program, Denver, Colorado on November 16, 2001. This paper presents some of the operational aspects and initial results of mudlog gas content. A detailed discussion of the computational aspects of mudlog gas content in both air and mud drilling are presented.
“Determining Coal Gas Content Using Mudlogging Methods”
Presented at the Denver Well Logging Society (DWLS-SWPLA) Luncheon Program, Denver, Colorado on April 20, 1999. This paper presents the theoretical development of mudlog gas content. Also included is how to calculate mudlog gas content. Applications and limitations are discussed.
