This paper presents a "direct" method to gas-oil interface level determination using an artificial neural network approach based on Electrical Capacitance Tomography (ECT) measurements. "Direct" here means that the gas-oil interface levels are obtained directly from the ECT measurements without recourse to image reconstruction. The preliminary work models a separation tank that i~ filled with g...

• The transportation and consumption of oil and natural gas in the continental United States may be directly affected by new regulations and legislation, including (1) the Clean Power Plan proposed by the U.S. Environmental Protection Agency (EPA), (2) railcar rules proposed by the U.S. Department of Transportation (DOT), and (3) proposed laws related to the controversial Keystone XL Pipeline e...

We quantify natural methane hydrate reservoirs by generating synthetic seismic traces and comparing them to real seismic data: if the synthetic matches the observed data, then the reservoir properties and conditions used in synthetic modeling might be the same as the actual, in-situ reservoir conditions. This approach is model-based: it uses rock physics equations that link the porosity and min...

Based on the latest laboratory test and prospect well data of G layer in south depression of D basin, the source rock、reservoir、cap-rock and preservation forming condition of tight oil and gas within research area is analyzed. The results indicate that the widely distributed dark mudstone of J layer has rather high organic content .IIb and III types are the mainly genetic types of organic matte...

Venezuela possesses the Western Hemisphere’s largest conventional proven oil reserves at 77.8 billion barrels and has proved natural gas reserves of 148 trillion cubic feet, the largest in Latin America and the seventh-largest in the world. Despite these abundant resources, economic performance of the country has been poor. Oil production declined steadily every year beginning in 1973 and by th...

In this paper we consider problems of optimization and selection of development systems (technologies) of oil/gas fields, consisting of some disjoint oil/gas pools (in terms of hydrodynamics), tied by resource constraints or general oil/gas production plan. In order to solve these problems, formulated as MILP models, we have developed approximate algorithm using Lagrangian relaxation (see Mikha...
