Oil-spill risk analysis: Outer Continental Shelf lease sale 144, Beaufort Sea. Final report
1995Co-Authors: C.m. Anderson, Walter R. Johnson, C.f. Marshall, E.m. LearAbstract:The Federal Government has proposed to offer Outer Continental Shelf lands in the Beaufort Sea for oil and gas leasing. Because oil spills may occur from activities associated with offshore oil production, the Minerals Management Service conducts a formal risk assessment. In evaluating the significance of accidental oil spills, it is important to remember that the occurrence of such spills is fundamentally probabilistic. This report summarizes results of an oil-spill risk analysis conducted for OCS Lease Sale 144, Beaufort Sea. The objective of this analysis was to estimate relative risks associated with oil and gas production for the proposed lease sale.

Oil-spill risk analysis: Central and western Gulf of Mexico Outer Continental Shelf Lease Sales 142 and 143. Final report
1992Co-Authors: J.m. Price, E.m. LearAbstract:The Federal Government has proposed to offer Outer Continental Shelf lands in the Gulf of Mexico for oil and gas leasing. Because oil spills may occur from activities associated with offshore oil production, the Minerals Management Service conducts a formal risk assessment. In evaluating the significance of accidental oil spills, it is important to remember that the occurrence of such spills is fundamentally probabilistic. The effects of oil spills that could occur during oil and gas production must be considered. The report summarizes results of an oil spill risk analysis conducted for the proposed Gulf of Mexico Outer Continental Shelf Lease Sales 142 and 143. The objective of the analysis was to estimate relative risks associated with oil and gas production for the proposed lease sales.

glacial lowstand deposits on the Outer Continental Shelf of southeastern australia
Quaternary Research, 1995Co-Authors: Marie A. Ferland, Peter S. Roy, Colin V MurraywallaceAbstract:Vibracores collected from water depths of 130 to 150 m on the Outer Continental Shelf of southeastern Australia contain evidence for several cycles of shallow marine deposition. One of these vibracores (112/VC/134; lat. 33°24′S, long, 151°58′ E) preserves evidence for the last three glacial lowstands, as inferred from radiocarbon dating, amino acid racemization, and fossil mollusc assemblages. The core contains the inner-Shelf molluscs Pecten fumatus, Placamen placidium, and Tawera gallinula, which today live in water depths of 10 to 50 m, in the cool waters of southern Australia. Radiocarbon dating and amino acid racemization analyses on multiple valves of P. fumatus in the core indicate three distinct age groupings of fossil molluscs: (1) those younger than 20,000 yr B.P., (2) those with minimum ages of about 100,000 yr, and (3) those with minimum ages of about 200,000 yr. We assign these sediments to oxygen isotope stages 2, 6, and 8, respectively. The core contains the first shallow-marine lowstand deposits to be recovered from the Shelf of eastern Australia. These deposits constrain the last three glacial lowstands on this margin to water depths <130 m below present sea level.

Outer Continental Shelf Leasing: Side-by-Side Comparison of Five Legislative Proposals
2008Co-Authors: Marc HumphriesAbstract:This report provides a side-by-side comparison of three bills and two proposals, each of which addresses oil and gas development in the Outer Continental Shelf (OCS).

Oil Development on Federal Lands and the Outer Continental Shelf
2008Co-Authors: Marc HumphriesAbstract:Over the past year, crude oil prices have nearly doubled, reaching record levels. Proposals before Congress include a number of legislative initiatives to increase domestic oil production. These proposals have fallen into two broad categories: (1) to open areas of the Outer Continental Shelf (OCS) which are currently under leasing moratoria; and (2) to encourage companies holding oil and gas leases to diligently develop leases to bring them into production. Proponents of these initiatives argue that promising areas should be open for exploration to maximize domestic oil production as quickly as possible. However, there are long lead times and often numerous considerations and constraints in getting federal oil and gas leases from the lease sale into production. Many leases never get explored before their primary lease term expires.

Outer Continental Shelf: Debate Over Oil and Gas Leasing and Revenue Sharing
2008Co-Authors: Marc HumphriesAbstract:Oil and gas leasing in the Outer Continental Shelf (OCS) has been an important issue in the debate over energy security and domestic energy resources. The Department of the Interior (DOI) released a comprehensive inventory of OCS resources in February 2006 that estimated reserves of 8.5 billion barrels of oil and 29.3 trillion cubic feet of natural gas. Congress has imposed moratoria of the OCS since 1982 through the annual Interior appropriation bills. Proponents of the moratoria contend that offshore drilling would pose unacceptable environmental risks and threaten coastal tourism industries. This report analyzes this issue in-depth, including budgetary information and relevant legislation.

Outer Continental Shelf Leasing
Offshore Service Industry and Logistics Modeling in the Gulf of Mexico, 2015Co-Authors: Mark J. KaiserAbstract:The Outer Continental Shelf Lands Act (OCSLA) is the key statute governing federal offshore oil and gas leasing and development. Enacted in 1953 and amended several times since, the OCSLA is the Department of Interior’s primary authority for managing leasing activity on the Outer Continental Shelf. Area-wide leasing releases for bid all unleased blocks in every lease sale, and so the government does not directly regulate how much acreage is leased outside the lease sales in the program plan. In this introductory chapter, the engine of OCS activity – lease sales – is reviewed, and the OCS leasing process and revenue components are described. Historic statistics on lease sale activity from 1994 to 2014, including acreage available, bid on and awarded, is summarized.

Modelling service vessel activity in the Outer Continental Shelf Gulf of Mexico
International Journal of Logistics Research and Applications, 2013Co-Authors: Mark J. Kaiser, Brian F. SnyderAbstract:Supply vessels transport goods and provide services to support oil and gas exploration, development and production activity throughout the world's offshore basins. The Outer Continental Shelf of the Gulf of Mexico is one of the oldest and largest offshore hydrocarbon producing regions in the world and is supported by an extensive offshore industry. The purpose of this paper is to model the activity level and spatial distribution of supply vessels operating in the Gulf's coastal regions in support of the oil and gas industry. The logistics network is modelled as a linear time-invariant deterministic system and implemented using an input–output model across 19 shorebases and 52 offshore area blocks. Historic activity levels and empirical data on vessel utilisation and shorebase allocation are used to parameterise the model. We estimate that about 80,000 trips per year are required to support the offshore industry with approximately 80% of trips in support of shallow water operations and 60% for production a...

economic limit of Outer Continental Shelf gulf of mexico structure production
Applied Energy, 2011Co-Authors: Mark J. KaiserAbstract:The economic limit of an oil and gas asset occurs when income from production is less than the direct cost of operation. Economic limits determine the threshold for profitable operations and are often considered from a conceptual perspective rather than as an object for empirical assessment. The purpose of this paper is to derive empirical estimates of the economic limit of offshore structures in the Outer Continental Shelf Gulf of Mexico. We classify 1962 decommissioned structures between 1986-2009 by structure type, primary production, water depth and year of removal, and compute end-of-life production, adjusted gross revenue, and water cut thresholds according to various levels of categorization. During the last year of production, historic gross revenues averaged $539,000 for oil structures, $955,000 for gas structures, and $1.1 million for dry gas structures. Daily end-of-life production ranged from 50 BOEPD for oil structures to 647 MCFEPD for gas structures and 788 MCFEPD for dry gas structures. The economic limits for oil and gas structures increased to $1 million and $1.7 million over the period 2005-2009.
