The primary goals of the DOE/NETL Natural Gas Hydrate Field Studies (NGHFS) project are:

• Conduct field-based studies that advance the ability to predict, detect, characterize, and understand distribution of and controls on natural gas hydrate occurrences.
• Analyze geologic, geochemical, and microbiologic data for indications of past and current changes to the stability of natural gas hydrate in marine settings.
• Develop links between the U.S. Gas Hydrate Program and international R&D efforts through direct participation in international field programs and workshops.
• Evaluate the potential role natural gas hydrates may play in the global carbon cycle through analysis of modern and paleo-natural gas occurrences.
• Provide expertise to domestic and international collaborators, focusing on activities such as pre-expedition/field site selection and evaluation and field/lab based analyses of samples and data collected in the field.
• Supply geologic expertise to DOE/NETL efforts to advance numerical simulation and field-relevant experimental studies.
• Work with the DOE’s domestic research partners, particularly those involved in major field operations in the Gulf of Mexico and Alaska, to ensure field test locations and plans are based on a full “gas hydrate systems” analyses.

Natural gas hydrates are solid compounds of gas molecules, predominantly methane, and water which generally occur in deep marine and arctic environments throughout the world. While the exact volume of natural gas trapped in hydrate is unknown, and the range of estimates varies widely, studies agree the amount is significant and hydrates are likely one of the largest storehouses of organic carbon worldwide. Thus, the potential of natural gas hydrates as a future energy resource, and persisting questions about the role hydrate plays in natural systems (climate and stability), has led to increased scientific, policy, and social interest in these occurrences worldwide.

There have been recent advances in the techniques and strategies used to prospect for and evaluate in situ gas hydrate in reservoir-quality sediments. However, these techniques and tools have been applied only to a limited number of field sites to date and, while promising, some remain inconclusive. Significant advances in technology are still required in order to better resolve and predict the distribution, occurrence, and saturation of gas hydrate-bearing sediments in heterogeneous media. In addition, longer-term studies via observatories or repeated evaluation of key field sites are required in order to monitor and understand the temporal constraints and changes of gas hydrate systems, particularly those most susceptible to changes in climate or other stability conditions.

The study of natural gas hydrate systems in the field provides invaluable information on these widely variable and complex systems. Results from the field can be utilized for experimental and numerical studies, which offer the potential to evaluate aspects of these systems on a variety of scales and through different methodologies. The research and technology requirements necessary to further advance our understanding of natural gas hydrate systems are significant. NETL Office of Research & Development’s (ORD) Natural Gas Hydrate Team conducts integrated research from the laboratory to the field and from molecular to reservoir-scale modeling, leveraging NETL-ORD’s strengths in geology, geochemistry, microbiology, and numerical simulation to improve understanding of these complex systems. The NETL-ORD’s field studies efforts are often aligned with other ORD R&D activities, key projects supported by the National Methane Hydrate R&D Program both domestically and internationally, and collaboration with external partners.

Project Description
The DOE/NETL NGHFS project studies naturally occurring gas hydrate systems ranging from microscopic to basin-wide scales using a three-pronged research approach (along with general hydrate program support). A greater understanding of the hydrate formation environment is developed through the application of geologic, geochemical, and microbiologic principles.

Geological Studies

Sedimentology and Lithostratigraphy
Detailed descriptions of cores from gas hydrate field expeditions provide a framework for integrating other site-related data sets. Changes in lithology, mineral composition, digenetic precipitates, sedimentary structures, and other attributes were used to better understand geochemical, microbiological, wireline log, and other micro- to meso-scale data sets. These data sets also provided insights into the lithologies represented by the wireline log and seismic responses, allowing for broader interpretation and evaluation of the lithostratigraphy and geology without having to undertake additional expensive core/drill operations.

Gas Hydrate Geological Systems Analysis
NETL, in conjunction with collaborators that included the U.S. Geological Survey (USGS) and the Bureau of Ocean Energy Management (BOEM), developed and applied a full geologic systems approach to the evaluation of gas hydrates in the field. This approach focused on a process that integrates geophysical detection with geological analysis of reservoir distribution (including sand, fractured shales, and combination reservoirs) and supporting petroleum systems elements including traps, seals, and migration histories.

While the petroleum systems approach is largely associated with energy exploration, this approach is equally applicable to the characterization of gas hydrate occurrences related to in-place estimates, global climate studies, and seafloor stability issues. This integrated approach is being used by the NGHFS team to contribute to the geologic assessments and characterizations of key field study sites, including potential future sites of drilling/coring programs in the Gulf of Mexico, and future production test sites located on the Alaska North Slope.

Geochemical Studies

NETL researchers, working in collaboration with researchers at Oregon State University, conducted geochemical projects which included:

• Investigation of the relationships among methane, gas hydrate, and methane flux dynamics in the Cascadia margin with emphasis on seafloor slope stability and how potential modulation of the events changes as a result of ocean circulation associated with glacial/interglacial cycles.
• Analyses of authigenic carbonates from key field study sites off the Cascadia Margin and Alaska North Slope for improved understanding of the processes that lead to the formation of digenetic precipitates, and the information they may provide about the evolution of and changes in active and paleo-methane flux through natural gas hydrate systems.
• Participation in South Korea’s 2010 Ulleung Basin Gas Hydrate (UBGH-02) Drilling Expedition in the East Sea and the processing and analysis of pore water geochemistry samples from this expedition.

Microbiological Studies

Examination of field study sites with a focus on improving understanding of the types of microorganisms that occur in different environments and how and when they produce and consume methane. This leads to improved numerical models and better understanding of methane sources and sinks in the natural environment.

Working in collaboration with researchers at Oregon State University, microbiology project personnel sought to identify the relationship between sediment features (e.g., grain size, hydrates presence) and the distribution, numbers, and activities of microbes within and proximal to hydrates in marine sediments.

General Geologic Support to U.S. Interagency Program
Members of the NGHFS team have served in an advisory role on the gas hydrates Interagency Technical Coordination Team that produced the Interagency Roadmap for Gas Hydrates R&D (2006 and 2009) and the Interagency Five-Year Plan for Methane Hydrate Research and Development (2007). Team members also participated in the creation and initial direction of the International Gas Hydrates Code Comparison effort.

Project Facilities
The primary NGHFS project laboratory, located in Albany, Oregon, included capabilities to analyze and conduct sedimentological studies on natural gas hydrate-bearing sediments using petrographic microscopy, particle size analysis, and X-ray diffraction (XRD)/X-ray fluorescence (XRF) analyses. In addition, the laboratory had advanced computational capabilities and software for spatial analysis, interpretation, and evaluation of gas hydrate-bearing systems using geophysical and geological data, including a variety of 3-D seismic surveys, seafloor bathymetric data, and geophysical well log data.

As a part of the affiliation between DOE/NETL and Oregon State University, the DOE/NETL Gas Hydrates Core Repository had been established within OSU’s Marine Geology Core Repository. The facility ensures the integrity of and public access to core collected during field expeditions. This allows for long-term preservation and analysis of these unique cores. The lab is equipped with state-of-the-art equipment, including Leica petrographic and binocular microscopes, a Mastersizer 2000 particle size analyzer, an InXitu XRD/XRF system, a Geotek core splitting system, and a Geotek multi-sensor core logger with XRF.

The lab has access to interpretive software packages, including Jade (XRD/XRF), Kingdom Suite (GIS geo-interpretation), Geographix (GIS geo-interpretation), and WellCad (lithostratigraphic interpretation/visualization).
