The paper describes combinatorial framework for planning of geological exploration for oil-gas fields. The suggested scheme of the geological exploration involves the following stages: (1) building of special 4-layer tree-like model (layer of geological exploration): productive layer, group of productive layers, oil-gas field, oil-gas region (or group of the fields); (2) generations of local de...

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...

I investigate the importance of learning in oil and gas exploration. I developed a tractable dynamic structural model of oil and gas exploration in which firms gradually learn about the productive qualities of different regions through exploratory drilling. Exploratory drilling is modelled as an information-gathering process in which each new exploratory well provides information concerning the...

Oil-gas reservoir exploration using hyperspectral remote sensing, which based on the theory of hydrocarbon microseepage information and fine spectral response of target, is a new direction for the application of remote sensing technology. In this paper, Qaidam Basin and Liaodong Bay in China were selected as the study areas. Based on the hydrocarbon microseepage theory, the analysis of crude oi...

Introduction: Occupational nature, strenuous physical activity, shift work, spatial and geographical location, as well as support facilities and equipment, pose greater risks to individuals in the oil and gas industry, especially those engaged in offshore oil exploration and production activities. The purpose of this article is to explain the issue of health and well-being of oil and gas indust...

Workers operating in the oil and gas exploration industries are at risk for exposure to sour gas—gas containing H2S (hydrogen sulfide) at potentially toxic levels. Operations located in densely populated areas pose additional threats of exposure to the general public. The danger can develop over time, even if the gas source was initially “sweet” (low in H2S). Local and national regulations defi...
