Naturally fractured carbonate reservoirs (NFCRs) comprise the majority of the oil and gas reservoirs around the Persian Gulf. Many of these reservoirs have a long history of exploitation, but vast amounts of oil remain in place. A major redevelopment process for light oil based NFRs will likely be the use of horizontal wells combined with gravity drainage at constant pressure based on voidage...
estimation of reservoir water saturation (sw) is one of the main tasks in well logging. many empirical equations are available, which are, more or less, based on archie equation. the present study is an application of radial basis function neural network (rbfnn) modeling for estimation of water saturation responses in a carbonate reservoir. four conventional petrophysical logs (pls) including d...
in this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. novel hybrid method coupling artificial neural network (ann) with genetic algorithm (ga) called ann-ga, was utilised. ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (hh) in the observation w...
It is common knowledge in the oil industry that the typical cost of drilling a new offshore well is in the range of $30-40 million, but the chance of that site being an economic success is 1 in 10. Recent advances in drilling technology and data collection methods have led to oil companies and their ancillary companies collecting large amounts of geophysical/geological data from production well...
Petroleum oil was used for many centuries in Egypt, China, Mesopotamia and Persia for heating, lighting, roadmaking and building. Small accumulations of oil were reported at Pechelbronn in Alsace in 1498 and in Poland in 1506, and Marco Polo noted 'oil springs' at Baku on the Caspian Sea in the latter part of the thirteenth century. Raleigh, in 1595, reported the existence of the Trinidad Pitch...
Well designed monitoring networks are essential for the effective management of groundwater resources but the costs of monitoring well installations and sampling can prove prohibitive. The challenge is to obtain adequate water quality and quantity information with a minimum number of wells and sampling points, a task that can be approached objectively and effectively using numerical optimizatio...
An Intelligent Supervision Scheme for the Industrial Production is presented in this work. Such scheme is tested for gas lift (GL) oil wells. The proposal is based on the possible production assessment, the process variables (specifically, the bottom-well pressures), and the operational scenarios detection for the process (in the case of study, as an oil producing well), with the objective of o...
Norman Wells crude oil was fractionated by sequential alumina and silicic acid column chromatography methods. The resulting nitrogen-rich fraction was analyzed by gas chromatography-mass spectrometry and showed 26 alkyl (C(1) to C(5)) carbazoles to be the predominant compounds. An oil-degrading mixed bacterial culture was enriched on carbazole to enhance its ability to degrade nitrogen heterocy...
