|Planning of a Marine Methane Hydrate Pressure Coring Program for the Walker Ridge and Green Canyon Areas of the Gulf of Mexico
||Last Reviewed 6/17/2014
The primary goal of this research is to develop scientific, operational, and logistical plans for a future methane hydrate-focused offshore coring program, including a scope of work, technical specifications, and schedule and budget estimate needed to implement a marine expedition.

Prior research efforts undertaken in numerous countries, including the United States, have made significant progress and have focused on offshore drilling campaigns whose goals have included direct sampling and testing of methane hydrates. Several such campaigns have been undertaken in the United States including, most recently, the DOE-supported and Chevron-led Gulf of Mexico Joint Industry Project (JIP) Leg I (2005) and Leg II (2009).
The JIP Leg II campaign was specifically conceived to investigate the nature of hydrate occurrences in sand-dominated systems, principally by means of logging-while-drilling operations. The campaign confirmed the presence of gas hydrate reservoirs at boreholes in both Green Canyon Block 955 (GC955) and Walker Ridge 313 (WR313) in the Gulf of Mexico. The locations for the two wells were selected utilizing prospectivity analysis based primarily on 3-D exploration seismic data. The success of the two wells was a significant achievement and legitimized the conceptual approach taken to prospect for potential methane hydrate reservoirs in deep water. Conclusions drawn from the 2009 JIP Leg II program included recommendations to perform additional research drilling programs to further delineate the potential hydrate resource through the use of pressure coring and pressure core analysis systems.
The overall focus of this project is to help enable—through detailed scientific and operational planning—the future collection of methane hydrate pressure cores, which will add to the body of scientific knowledge of the characteristics of in situ methane hydrate occurrences and contribute to scientific and engineering efforts to assess potential exploitation of methane hydrates as an energy resource.
The project will consist of a study resulting in the preparation of detailed plans and recommendations for all aspects of a future offshore hydrate-focused research campaign.
The project will help guide and enable future field-based collection of hydrate data through the completion of detailed logistical, scientific, technical, and operational plans. These plans will facilitate the conduct of future marine hydrate research expeditions, which represent a critical path to collecting the data needed to characterize the occurrence and behavior of oceanic hydrates and, ultimately, assess their feasibility as a potential future energy resource.
- Completed a notional project execution plan for a field expedition that will help identify critical information for operational and logistical plans and which provides a mechanism to include lessons learned from recent marine hydrate research expeditions.
- Established plans for internal project workshop (May 2014), which will be focused on developing the key structure of operational and logistical plans under the project. Established initial plans for a peer review workshop with a wider group of hydrate research experts.
Current Status (June 2014)
Researchers are developing a baseline approach for how to best define research expedition needs, which has led to a notional project execution plan used in conjunction with an internal workshop (with drilling, logging, and hydrate research experts) to develop research expedition/coring program concepts. The resultant coring program concepts will be evaluated by a wider group during a peer review workshop tentatively slated for July 2014. the project team will incorporate feedback and input from the peer review workshop to fully develop operational and logistical plans for the marine hydrate coring expedition based on the agreed upon program concept.
