PEOffice User Guides - ProdAnaReservoir Engineering Analysis 9PEOffice’s Reservoir Production Analysis modules can be easily employed by production oroperation engineers worldwide. The ProdAna module can to help them inquire, monitor, count,compare and analyze oil and gas production flows. The ProdForecast module can be used togenerate a production forecast based on decline curve analysis, material balance and varioustype-curves. With a reservoir production model built, users can conduct production historymatching as well as generate future production predictions using the SimON Black OilReservoir Simulator. Based on an internal database, with its easy operating mode and well-developed algorithm, Reservoir Production Analysis is a very powerful analytical tool forproduction and operation engineers.9.1 ProdAna (for Oil & Gas) Production Statistics and Analysis9.1.1 IntroductionAbout ProdAnaSome of the most important tasks associated to routine production analysis or long-term oilfielddevelopment are to capture production behaviors by statistics and analysis. Given the overwhelmingamount of production or injection data, ProdAna is the ideal tool for engineers to quickly and easily:query data, calculate statistics, compare production by wells or periods and generate powerfulproduction plots, contour maps and bubble maps and create user-define production indexes.256
PEOffice User Guides - ProdAnaMain Functions and FeaturesMain FunctionsQuick Production Data Processing Quick field data access and preparation of data for analysis Statistical analysis and theoretical production evaluationUser Defined Production Data Query User-defined query filters and report formats. Reports can be scheduled and generated on daily, weekly and monthly basis. Production and injection data can be tabulated and plotted in user defined format. Production and injection plots can be generated by well, well group , or field basis. Production plots can be annotated with important events/ notes. Comparisons of production or injection with a pre-selected sample can be easily performed and acorrelation can then be generated Production Statistical AnalysisProduction statistical analysis including oil and water production and pressure (casing liquid fluidlevel and bottom hole). Integrated statistical analysis of different production indices Production index statistical analysis can be based on a pre-set time period.Production Data Comparison Capability Comparison can be performed against a pre-set standard or among groups on production dataincluding liquid rate, oil rate, water cut, pressure (casing liquid level and static liquid level),cumulative production and water injection rate.
