We use the model described in Piri and Blunt [Phys. Rev. E 71, 026301 (2005)] to predict two- and three-phase relative permeabilities of Berea sandstone using a random network to represent the pore space. We predict measured relative permeabilities for two-phase flow in a water-wet system. We then successfully predict the steady-state oil, water, and gas three-phase relative permeabilities meas...

phase-in of federal income taxes, Congress allowed oil and gas companies to deduct 27.5 percent of gross revenues (up to half of net income) for corporate income tax purposes. Characteristically, a tax policy that began as a technical adjustment of the tax code turned into a deliberate measure to stimulate oil and gas production. The deduction was a big hit with the industry because it far exce...

Tar removal from biomass gasification gas is a crucial problem in applying syngas from biomass for its downstream applications. Catalytic biomass gasification has given promising results for tar cracking. A few research groups have investigated the use of olivine for tar cracking [2,3,4,7,8,9,10]. The presence of oxides of iron and magnesium in the mineral olivine give it the ability to crack h...

Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a eld with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil wells of the eld such that the total production of oil from the eld is maximized. This paper describes a non-linear optimization problem with constra...

This report analyzes the technical aspects and the economics of utilizing nuclear reactor to provide the energy needed for a Canadian oil sands extraction facility using SteamAssisted Gravity Drainage (SAGD) technology. The energy from the nuclear reactor would replace the need for energy supplied by natural gas, which is currently burned at these facilities. There are a number of concerns surr...

Many world class large carbonate reservoirs leave behind at least half of the initial oil in place. Typically water injection is used to improve oil recovery while gas injection is used to maintain pressure or to promote oil gravity drainage. Immiscible gas injection, including injection of CO2, has been considered but not implemented on a large scale for economic reasons. Furthermore, interest...

Oil and gas industry operations span the globe, encountering unique operational and business climates in a variety of regions. This reality presents many challenges for companies that are characterizing their greenhouse gas (GHG) emissions and developing GHG management strategies for diverse multinational facilities. For these companies, the consistency, reliability, and credibility of the meth...

BACKGROUND Higher risk of exposure to environmental health hazards near oil and gas wells has spurred interest in quantifying populations that live in proximity to oil and gas development. The available studies on this topic lack consistent methodology and ignore aspects of oil and gas development of value to public health-relevant assessment and decision-making. OBJECTIVES We aim to present ...

Quantitative information regarding the endmember composition of the gas and oil that flowed from the Macondo well during the Deepwater Horizon oil spill is essential for determining the oil flow rate, total oil volume released, and trajectories and fates of hydrocarbon components in the marine environment. Using isobaric gas-tight samplers, we collected discrete samples directly above the Macon...
