This book was released on 2004 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Methane hydrates consist of a water ice lattice with methane gas molecules contained in the lattice cavities. When dissociated into its constituent water and methane, one volume of hydrate contains approximately 138 volumes of methane gas. On the North Slope area of Alaska, it is estimated that accumulations containing between 300 and 5000 trillion cubic feet of gas. The feasibility of a pilot production project was computed to determine the production potential of the hydrate accumulation and its economic return. The production of gas from a 1 mile by 4 mile reservoir block containing hydrate underlain by an accumulation of free gas was simulated and the resulting production profile inputted into an economic model. As the mechanism for the production of hydrates differs from conventional hydrocarbons, an existing thermal hydrocarbon computer simulation program was adapted. Results of the simulations indicate that depressurization of the free gas zone reduces the pressure at the gas-hydrate interface below that necessary for hydrate stability and causes the hydrate to dissociate into methane gas and water. Analysis found that, in most situations, a development project would be profitable, though the results are highly leveraged to the transportation cost and gas sales price"--Leaf iv.

This book was released on 2009 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Mt. Elbert prospect is a naturally occurring hydrate interval on the Alaska North Slope. Of interest are its permeability characteristics which can aid in the quantification of hydrates' resource potential. For this study an experimental apparatus was utilized to measure gas-water relative permeability of unconsolidated core sample containing methane hydrates. A Magnetic Resonance Imager (MRI) was used to qualitatively determine how hydrates form in core samples during these types of experiments. Finally, reservoir simulation studies were performed to investigate how hydrate deposits such as Mt. Elbert may be ultimately produced. Results indicate that permeability of porous media is severely affected by hydrate saturation. Relative permeability as determined by unsteady-state displacement has the appearance of "piston-like" displacement. MRI data suggests that hydrate saturation is relatively uniform. Simulation studies suggest that deposits like Mt. Elbert are not first choice targets for gas production"--Leaf iii.

Download or read book Realizing the Energy Potential of Methane Hydrate for the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-30 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas, composed mostly of methane, is the cleanest of all the fossil fuels, emitting 25-50% less carbon dioxide than either oil or coal for each unit of energy produced. In recent years, natural gas supplied approximately 20-25% of all energy consumed in the United States. Methane hydrate is a potentially enormous and as yet untapped source of methane. The Department of Energy's Methane Hydrate Research and Development Program has been tasked since 2000 to implement and coordinate a national methane hydrate research effort to stimulate the development of knowledge and technology necessary for commercial production of methane from methane hydrate in a safe and environmentally responsible way. Realizing the Energy Potential of Methane Hydrate for the United States evaluates the program's research projects and management processes since its congressional re-authorization in 2005, and presents recommendations for its future research and development initiatives.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas hydrates have long been considered a nuisance by the petroleum industry. Hydrates have been hazards to drilling crews, with blowouts a common occurrence if not properly accounted for in drilling plans. In gas pipelines, hydrates have formed plugs if gas was not properly dehydrated. Removing these plugs has been an expensive and time-consuming process. Recently, however, due to the geologic evidence indicating that in situ hydrates could potentially be a vast energy resource of the future, research efforts have been undertaken to explore how natural gas from hydrates might be produced. This study investigates the relative permeability of methane and brine in hydrate-bearing Alaska North Slope core samples. In February 2007, core samples were taken from the Mt. Elbert site situated between the Prudhoe Bay and Kuparuk oil fields on the Alaska North Slope. Core plugs from those core samples have been used as a platform to form hydrates and perform unsteady-steady-state displacement relative permeability experiments. The absolute permeability of Mt. Elbert core samples determined by Omni Labs was also validated as part of this study. Data taken with experimental apparatuses at the University of Alaska Fairbanks, ConocoPhillips laboratories at the Bartlesville Technology Center, and at the Arctic Slope Regional Corporation's facilities in Anchorage, Alaska, provided the basis for this study. This study finds that many difficulties inhibit the ability to obtain relative permeability data in porous media-containing hydrates. Difficulties include handling unconsolidated cores during initial core preparation work, forming hydrates in the core in such a way that promotes flow of both brine and methane, and obtaining simultaneous two-phase flow of brine and methane necessary to quantify relative permeability using unsteady-steady-state displacement methods.

Download or read book Geologic Interrelations Relative to Gas Hydrates Within the North Slope of Alaska written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The five primary objectives of the US Geological Survey North Slope Gas Hydrate Project were to: (1) Determine possible geologic controls on the occurrence of gas hydrate; (2) locate and evaluate possible gas-hydrate-bearing reservoirs; (3) estimate the volume of gas within the hydrates; (4) develop a model for gas-hydrate formation; and (5) select a coring site for gas-hydrate sampling and analysis. Our studies of the North Slope of Alaska suggest that the zone in which gas hydrates are stable is controlled primarily by subsurface temperatures and gas chemistry. Other factors, such as pore-pressure variations, pore-fluid salinity, and reservior-rock grain size, appear to have little effect on gas hydrate stability on the North Slope. Data necessary to determine the limits of gas hydrate stability field are difficult to obtain. On the basis of mud-log gas chromatography, core data, and cuttings data, methane is the dominant species of gas in the near-surface (0--1500 m) sediment. Gas hydrates were identified in 34 wells utilizing well-log responses calibrated to the response of an interval in one well where gas hydrates were actually recovered in a core by an oil company. A possible scenario describing the origin of the interred gas hydrates on the North Slope involves the migration of thermogenic solution- and free-gas from deeper reservoirs upward along faults into the overlying sedimentary rocks. We have identified two (dedicated) core-hole sites, the Eileen and the South-End core-holes, at which there is a high probability of recovering a sample of gas hydrate. At the Eileen core-hole site, at least three stratigraphic units may contain gas hydrate. The South-End core-hole site provides an opportunity to study one specific rock unit that appears to contain both gas hydrate and oil. 100 refs., 72 figs., 24 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of the North Slope Hydrate Study is to evaluate the methane hydrate potential of the Walakpa gas field, a shallow gas field located near Barrow, Alaska. Observing, understanding, and predicting the production characteristics of the Walakpa field will be accomplished by the analysis of the reservoir geology, and of the individual well production data, derived from reservoir engineering studies conducted in the field.
