Stratigraphy and Petroleum Production potential of the Spearfish Formation in North Central North Dakota
… water has been a source of significant production problems for operators. The key to developing the area is to keep the individual fracs large enough to stimulate the tight Spearfish sands but not to let them propagate into the underlying water zone. </p><p>The Spearfish Formation of the …

Assessment Of Disruption Risk In Supply Chain The Case Of Nigeria’s Oil Industry
evaluate disruption risks in the supply chain of petroleum production. This methodology is developed to formalise and facilitate the systematic integration and implementation of various models; such as analytical hierarchy process (AHP) and partial least squares structural equation model (PLS-SEM) …

Efeito do envelhecimento e da geração de “whitening” no comportamento mecânico do PVDF
… in the composition of flexible pipes used in petroleum production offshore, acting as sealing layer. One effect named whitening can appear in the material, being characterized by the formation of whitened regions and is associated with cavitation process (growth of microvoids). This work has …

Land Use of Conflicts in Tulsa County, Oklahoma: Urban Expansion Vs. Petroleum Development
… in Tulsa County, Oklahoma, where significant petroleum deposits are found in rapidly expanding suburban communities. This study focused on the southwest quadrant of Tulsa County, which contains the communities of Jenks, Bixby, and Glenpool. The goal of this study was to develop a recommended …

Paleocurrent Analysis of the Cretaceous Mitchell Formation, North-Central Oregon
… renamed the Mitchell Formation are potential petroleum source and reservoir rocks. Thus, determining their extent under the cover of Tertiary volcanics is of great importance to future petroleum exploration in the southern half of the Columbia Basin. The direction of sediment transport has …

Novel covalent organic framework (COF) thin-film composite nanofiltration membrane for effective removal of organic compounds from petroleum produced water
Petroleum-produced water is the co-produced aqueous liquid phase along with the oil and/or gas phases during petroleum production operations. It’s considered the largest waste stream associated with oil and gas extraction. The treatment and further reuse of produced water are essential to address …

Abordagem algébrico-diferencial na simulação unidimensional do escoamento bifásico em dutos
… in industrial applications, as is the case of petroleum production and refining, transportation of natural gas and nuclear power reactors. Simulation and design of such process facilities demands that efficient and accurate numerical methods be applied to equally accurate two-phase flow …

The Spectacle of Neoclassical Economics: The Chad-Cameroon Petroleum Development Project and Exploitation in the Niger Delta and the Chad Basin
… I engage the case of the Chad-Cameroon Petroleum Development Project (CCPDP) to argue that the neoclassical economic shift is a spectacle or exhibit, irrelevant in important ways to exploitation “on the ground.” Contrary to neoclassical economics and World Bank development rationales, …

Investigations of Asphaltene-Metal Interactions
Asphaltenes are the most polar fraction of petroleum that can precipitate due to changes in pressure, temperature and composition which may be encountered during petroleum production and transportation. The precipitated asphaltenes can subsequently deposit on the surfaces of …

Contesting for power in public performance: hegemonic struggles in the Louisiana Shrimp and Petroleum Festival
… annual performance of the Louisiana Shrimp and Petroleum Festival of that city. The information utilized in this study was assembled from a variety of sources: newspaper reporting from 1935 to 1999, chronicling the Festival and related subjects; works of several theorists in the area of ritual …

Gas lift optimization utilising automation gas lift valve
… fluid since the column of corresponding water in petroleum production tubing has the highest hydrostatic pressure of 2.8 psig compared with crude oil. Hence, during the gas lift process crude oil will be less cumbersome to produce than water. The results present the maximum production rate of 18.3 …

Gas lift optimization and flow instability
… when it is depleted or insufficient. During oil production, this method can be affected by two-phase (gas-liquid) flow instability within the production tubing, which results in a reduction in the total oil recovered. There are three main flow instabilities caused by, the density wave …
