The Gas Research Institute has sponsored research directed towards improving the recovery efficiency and reducing the cost of producing gas from tight reservoirs. In support of the goal, the Staged Field Experiment (SFE) project was implemented. The document provides the results of the research work performed on the SFE No. 4 well. Following an extensive site selection effort, the Frontier Formation along the Moxa Arch was selected as the target formation for SFE No. 4 research. Cooperative well data acquisition and analysis led to the selection of the SFE No. 4 site in the Chimney Buttes Field located in Section 24, T28N R113W. The open-hole and data acquisition programs designed and implemented on the SFE No. 4 well supported the goal of determining the most effective combination of formation evaluation (geological, petrophysical and engineering), fracture diagnostics, hydraulic fracturing and fracture modeling techniques to reduce the cost of producing gas from tight formations such as the Frontier. Analyses of these data, presented in detail in the report, determined that the target Second Bench of the Second Frontier was found to have a thin (approximately 10 ft), tight (ranging from 0.004 to 0.008 md) reservoir unit which had pre-frac flow rates measured at 9 MCFD. Higher than expected stress gradients were measured in in-situ stress tests. Several fluid-only mini-frac injections were attempted but aborted when pressure limitations of surface equipment were reached.
