NEDO has developed MEPAS, a software for exploration of geothermal reservoir. MEPAS has bcen developed as a tool for geologists to analyze earthquakes and find fractures by comparing earthquakes with other exploration data. MEPAS consists of a seismic data processing part and a geological analysis part. The geological analysis part features 3D display, time and space distribution display, fract...

Well testing is of great importance in petroleum engineering, to have a kind of firsthand knowledge and estimating formation permeability, wellbore damage/ skin, etc. These parameters are further required to estimate production rate from a well and at the same time gives an idea of its productivity. These reservoir related parameters calculation is strongly dependent on formation thickness. Any...

Gas reservoirs with low permeability (k<0.1 mD) are among the unconventional reservoirs and are commonly termed as "Tight Gas Reservoirs". In conventional gas reservoirs that have high permeability, the flow of gas is basically controlled by the reservoir permeability and it is calculated using the Darcy equation. In these reservoirs, gas flow due to gas diffusion is ignored compared to Dar...

Unconventional gas reservoirs have shown the potential to be the next world primary energy resource and have received a lot of attention in the past few years in the world. Even with the significant progress that has been made world-wide towards commercial development of natural gas from these unconventional resources, understandings or modeling tools of gas flow in these extremely low-permeabi...

Gas reservoirs usually have high recovery due to high mobility and low residual gas saturation, although some of them producing under water-drive mechanism have low recovery efficiency. Encroachment of water into these reservoirs traps considerable amount of gas and increases the maximum residual gas saturation, which results in the reduction of gas and condensate production. Generally, the rec...

The main goal of this paper is to use the multilayer perceptron neural network to suggest a 3D cube of the Total Organic Caron (TOC) in the lower Barnett shale gas reservoir. 3D Poststack seismic data recorded near two horizontal wells drilled in the lower Barnett formation are used as an input to train the neural machine, while the calculated acoustic impedance from sonic and density well-logs...

Unconventional reservoirs are keys to oil and gas exploration and development, especially shale gas reservoirs. Discriminated shale gas reservoir lithofacies are, in particular, a primary problem in shale gas reservoir engineering. The mineral composition will affect both absorbed and free gas contents, therefore their identification is important. The mineral composition is one part of lithofac...

Production of gases from gas-condensate reservoirs are known to bear certain challenges largely due to the formation of retrograde condensates that hinder gas flow. The drop out of this liquid creates flow regions that are characterized by the liquid saturation as it affects the mobility of the two phase flow, thereby preventing the effective modeling of well productivity. In this study, a pred...

Carbon Dioxide Storage in Natural Gas Reservoir — The general idea of CO2 disposal in gas reservoirs is that the underground volume of the ultimately recoverable hydrocarbons (gas and condensate) is replaced by CO2. This paper investigates the feasibility of carbon dioxide disposal in depleted gas reservoirs. Gas reservoirs are a practical storage site for the carbon dioxide, because the presen...
