Many firms in the oil and gas business have long used decision analysis techniques to evaluate exploration and development opportunities and have looked at recent development in option pricing theory as potentially offering improvements over the decision analysis approach. Unfortunately, it is difficult to discern the benefits of the options approach from the literature on the topic: Most of th...

Underground gas storage is the practical means of making available the increased supplies of natural gas that are needed in Indiana in winter periods of peak demand. To date, 21 gas storage projects providing an estimated storage capacity of 48 billion cubic feet have been initiated. Expansion of storage capacity is anticipated. Basic geologic factors and availability of subsurface information ...

gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. it occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. oil phase will form films which are produced under gravity forces (film flow). many gas injection experiments have been done on laboratory scales with d...

biodegradation of petroleum hydrocarbons (20 g/kg dw soil) was investigated in 3 media, differing in the kind of petroleum fractions. in the laboratory experiments, during 5 months, the activities of petroleum hydrocarbon-degrading microorganisms and dehydrogenase activity of soil was determined. gas chromatographic analysis showed the biological decontaminations for gas oil, kerosene and synth...

In recent years, an increasing number of oil and gas projects involving drilling through salt have been presented by different exploration companies. It is important for underwriters, lawyers, regulators, financiers and engineers to have a clear understanding...

The Oil & Gas Journal, in 2004, states that CO2 flooding is the fastest-growing enhanced oil recovery technique in USA, and production derived from CO2 projects has more than tripled from 50,000-Barrels/day to 200,000-Barrels/day. Cyclic injection of CO2 and N2 combines environmental benefits attendant to reducing CO2 concentrations in the atmosphere and economic benefits realized through impro...

Gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. Experimental studies showed that an application of a combined technology of Gas Assisted Gravity Drainage (GAGD) and Vapor Extraction (VAPEX) could increase final oil recovery of a candidate viscous oil reservoir. In this paper the results of laboratory investigation are presented, including Pressure-Volu...
