We use a multi-resolution analysis based on a wavelet transform to upscale a 3D fractured reservoir. This paper describes a 3D, single-phase, and black-oil geological model (GM) that is used to simulate naturally-fractured reservoirs. The absolute permeability and porosity of GM is upscaled by all the possible combinations of Haar, Bior1.3, and Db4 wavelets in three levels of coarsening. The ap...

Geological Survey (USGS)— among many others—deliv-ered a verdict of gloom in 1919: The country would run out of oil within 9 years! (1) Facing mounting hysteria, President Coolidge set up the Federal Oil Conservation Board in 1924, to draft legislation to preserve national resources. After the conversion of Great Britain's naval fleet from coal to oil in 1914, the UK also feared that it would b...

The knowledge and the forecast of the parameters which rule the downflow models in oil extraction and transport are today of paramount importance. In particular the extracted oil is mixed with water and gas in rates which differ not only from different wells, but also on the same well during its life. The main problems involved with the measurement of the flow rates are : well exhaustion, criti...

A proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. This paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. For this aim, DST and PVT data of exploration and production wells of a supergiant offshore gas condensate reserv...

this paper estimates the determinants of inflation in iran using a linear and non- linear regression model over the period 1959-2008. in the model specification, the conventional variables (liquidity, production and exchange rate) as well as positive and negative oil revenue shocks, monetary disequilibrium, and demand gap are considered. the results show that nonlinear time series regression mo...

The increased demand for oil and gas places a burden on lands set aside for natural resource conservation. Oil and gas development alters the environment locally and on a much broader spatial scale depending on the intensity and extent of mineral resource extraction. The current increase in oil and gas exploration and production in the United States prompted an update of the number of pipelines...

Increased production from gas lifted oil wells can be achieved by use of feedback control. Without control the well system may have large oscillations in the flow rate or stabilize itself at a non-optimal production point. These non-optimal production conditions give lower production and/or poor oil/water downstream separation. The study extends the newly introduced approach for controlling gas...

Highlights of GAO-07-283, a report to congressional requesters The U.S. economy depends heavily on oil, particularly in the transportation sector. World oil production has been running at near capacity to meet demand, pushing prices upward. Concerns about meeting increasing demand with finite resources have renewed interest in an old question: How long can the oil supply expand before reaching ...

Heavy organics deposition is a common problem in oil industry, especially in oil production, transportation and processing. Wax or solid paraffin series are examples of heavy organics that deposit. Precipitation and crystallization of wax causes major difficulties in different processes. Based on multi-solid theory, a basic model is modified in this paper for wax precipitation in different oils...
