Production Plot & Decline Curve Analysis Description

Work is partially supported by the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) under Grant Number DE-FE0002056.

This is the production plot & decline curve analysis web application, which allows the user to access production data from the Kansas Geological Survey (KGS) Database for Leases, Fields, Operators and Counties. The web application was designed to read production from the user's PC as an ASCII Extensible Markup Language (XML) file or as a comma-separated values (CSV) file. See examples for format, XML (Arroyo Field) and CSV (Arroyo Field). A "spread sheet" like table was provided to display the data retrieved, but editable to allow the user to add data to the existing list, i.e., download production data from the KGS Database and insert missing months or previous years that may not be recorded.

The Program allows the user to save the raw production data as an ASCII Extensible Markup Language (XML) file or as a comma-separated values (CSV) file, see examples above. The Program allows the user to save the Production Plot Java Image to their PC as a Portable Network Graphics (PNG) Image, the Program will then display a web page with the image file with a link at the top of the page that will allow the user to launch the PDF Web Applet to convert the PNG Image File to a Portable Document Format (PDF) File.

A decline curve analysis dialog was included to allow the user to predict the economic limit for a specific lease, field, operator and county. This analysis uses three methods for predicting the deline of a reservoir, exponential, harmonic and hyperbolic.

This web application will take advantage of over 11 years of Java development experience at the Kansas Geological Survey (KGS) in developing web applications that plot oil & gas data and allows the geologist to perform analysis with that data, i.e. GEMINI Project & Tools on the KGS Web Site.

GEMINI (Geo-Engineering Modeling through INternet Informatics) Project was developed to allow the geologist to seamlessly integrate databases and geological analytical tools across the web. Analytical tools were designed for the independent oil and gas operators, consultants, and widely separated team members within and outside companies.
