Assessment of Reservoir Performance of a Well in South-Eastern Part of Bangladesh Using Type Curve Analysis

摘要

Natural gas is one of the most significant asset for a nation. It is very noteworthy for a country to analyze the characteristics and other parameters of a gas reservoir for the better maintenance. There are different types of methods to carry out these tasks and typecurve analysis is one of them. This is an essential method for sustaining controlled production, properties characterization and finding most capable production procedure. Expected ultimate recovery (EUR), permeability, skin factor, drainage area, volume, original gas in place based on production rate and pressure can be evaluated by different types of analysis such as Fetkovich analysis, Blasigimme analysis, AgarwalGardner Type curve analysis, flowing Material Balance and NPI type curve. Here an investigation has been directed to estimate gas initial in place (GIIP) and more specified parameters of the wells of a gas field in Bangladesh locating at the south-eastern part of the country. This field is contributed through five (5) wells. In this study, we gathered pressure and production rate information for Well #04 that were acknowledged throughout periodic Shut-in. typecurve analysis has been calculated to understand different reservoir characteristics and forecast for future production. The result that was instigated through this research is considered among the greatest satisfactory than any other reserve estimation method because the data is imperiled to real field.
