Risk Factors in Oil and Gas Well Electronics Compared to Other Electronic Industries — The oil and gas well electronics industry is a low volume industry in which the development and the operating life cycles of the electronic products used is considerably longer than those of the commonly available commercial parts used to build them. Oil and gas well electronic systems, especially the ones th...

We investigate the effect of different saturation histories relevant to various oil displacement processes (including secondary and tertiary gas injections) on three-phase gas/oil/brine relative permeabilities of water-wet sandstone. It is found that three-phase water (wetting phase) relative permeability is primarily a function of water saturation and shows no dependency upon saturation histor...

Carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. Depending on the operating pressure, the process might be miscible or immiscible. Minimum miscibility pressure (MMP) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. The miscibility condition is determine...

Detection of Metal Defects on Gas Distribution Pipeline by Remote Field Eddy Current (RFEC) Using Finite-Element Analysis — It is necessary to find out whether there are metal defects on underground gas distribution pipelines without excavation in order to establish safety strategies for replacement or maintenance. The metal defects are classified into general corrosion, stress corrosion cracki...

Oil and natural gas have been produced in Wyoming since the late 1800s although the rate of extraction has increased substantially in the last two decades. Well pads, roads, and infrastructure built to support resource development alter native vegetation configuration; however, the rate and effect of land cover change resulting from oil and gas extraction has not been quantified across the regi...

Hydrocarbon gases were collected from well cuttings and core at the MtElbert-01 gas hydrate stratigraphic test well, drilled within the Milne Point field on the Alaska North Slope. Regionally, the Eileen gas hydrate deposits overlie the more deeply buried Prudhoe Bay, Milne Point, and Kuparuk River oil fields and are restricted to the up-dip portion of a series of nearshore deltaic sandstone re...

turkey as a country located between the main energy resources and the european :union: can play the role of a natural bridge in energy transportation. the eu countries have always tried to find some alternative routes for russian energy pipelines and turkey could be one of the best options. although turkey is poor in oil and natural gas resources, however, this country can play a strategic role...

The most costly operation in the oil exploration is the well network drilling. One of the most effective ways to reduce the cost of drilling networks is decreasing the number of the required wells by selecting the optimum situation of the rig placement. In this paper, Balas algorithm is used as a model for optimizing the cost function in oil well network, where the vertical and directional dril...
