In view of the problem huge computations and multiple solutions, a method for optimizing accelerating progress history matching by using material balance analysis was established. Based on simple measuring data, such as average pressure, daily production rate PVT test, model can be constructed three phase system hydrocarbon reservoir. According to calculation, original oil in place aquifer para...

Abstract Determination of gas in place (GIP) is among the hotspot issues field oil/gas reservoir engineering. The conventional material balance method and other relevant approaches have found widespread application estimating GIP a or well-controlled reserves, but they are normally not cost-effective. To calculate abnormally pressured reservoirs economically accurately, this paper deduces an it...

The limiting efficiency of photovoltaic energy conversion was determined by Shockley and Queisser using the theory of detailed balance, which described the balance between absorption and emission of photons. However, when a material is placed on top of a solar cell that modifies the transmission of photons (e.g., a photonic crystal), both the absorption and emission of photons are modified. Her...

The storage of carbon dioxide by injecting into gas reservoirs has become an important technique for achieving capture, utilization, and storage. However, most studies have focused on tight reservoirs, there are still few the injection water-bearing reservoirs. This paper analyzes variation reservoir pressure during CO2 points out optimal amount in reservoir, which can provide theoretical guida...
