|Alaska North Slope Gas Hydrate Reservoir Characterization||Last Reviewed 11/29/2013|
The goal of this project is to characterize the large in-place methane hydrate resource on the Alaska North Slope (ANS) and to conduct field and lab studies to determine the potential for methane, produced from hydrate, to become a viable part of the overall energy supply.
Assessments produced by the U.S. Geological Survey (USGS) have estimated that 85 trillion cubic feet (tcf) of undiscovered, technically recoverable gas resources exist within gas hydrates in northern Alaska. Past USGS assessments indicated 40 tcf of the resource may exist within hydrate deposits below existing oil and gas production facilities. In 2001, BP Exploration Alaska Inc. proposed a state-of-the-art 3-D seismic survey over its Milne Point production unit to provide a starting point for a full evaluation of the feasibility of commercial production from Arctic hydrates.
Efforts under this project have been broken into several operational phases. Phase 1 focused on the evaluation and development of lab, modeling, and field techniques and technologies required for assessment of ANS hydrates and for conducting field-based operations planned in later project phases. Phase 2 focused on actual assessment of ANS hydrate resources and the operational planning for future field testing. These initial phases implemented fully integrated, detailed geophysical interpretation and modeling; regional geologic characterization of prospective hydrate-bearing units; and advanced reservoir and economic modeling to select a location for drilling, coring, and potential production testing. Phase 3 concentrates on activities necessary to achieve a long-term, depressurization-based, field test of methane production from an ANS hydrate reservoir. To date (Phase 3A), this has included the drilling, logging and coring of a stratigraphic hydrate test well in the Milne Point Unit as a mechanism to verify reservoir characterizations and to test techniques and technologies necessary to prepare for a long-term production test in Phase 3B.
This project will be a critical first step in determining the commercial viability of methane production from arctic hydrate deposits. The project has greatly advanced the tools and techniques used to delineate specific hydrate prospects and to model the potential productivity and commercial viability of those prospects. The project could also (assuming continuation through all project phases) provide the first extended production testing of a U.S. gas hydrate reservoir and yield insight into the relative merit of various contemplated production and stimulation methods for gas hydrate.
Field Testing (Phase 3)
Assessment and Planning (Phases 1 and 2)
Current Status (November 2013)
Efforts under Phases 1?3A have been completed and the project is currently in a holding pattern awaiting potential opportunities to either gather additional hydrate resource characterization data for the ANS or move into a final production testing phase (Phase 3B). Potential opportunity to move into a long-term hydrate production test phase under this project is complicated by many factors; the project team continues to investigate options to enable such a test. DOE and BP also continue to look for potential opportunities to gather additional hydrate-relevant characterization data from ANS wells of opportunity.
