An integrated set of analytical tools Oil, Gas, Aquifers All common methods + Sills Unique “Outline Style” user interface

A comprehensive Material Balance Program

Material Balance Analysis and Forecasting

TANK

Tank is a powerful analytical tool for reviewing and predicting the performance of combination drive oil and gas reservoirs. Tank couples a general form of the material balance equation with a choice of analytical aquifer models, allowing it to handle a wide range of hydrocarbon fluid types and reservoir drive mechanisms. Given a reservoir’s performance history, Tank can be used to estimate original hydrocarbons in place and aquifer size and strength. Once these parameters have been quantified, Tank may be used to review and predict reservoir and aquifer performance using a variety of analytical techniques.

SLIDE 17

Programs available for customization and implementation

Beampump, Bubblemap, Patternflood, and Wellbore

Patternflood:

A map based plotting and material balance package that balances voidage, influx, injection, and flux through a field’s waterflood patterns. Although data input is significant, resulting pattern balancing results can be used to more efficiently manage waterflood injection and withdrawal. The functionality in this program is superseded by both DSS and OFM.

Tools for Evaluation : A review of the SOS Software Maintain and improve viable programs.

Petroskills funded SI units upgrade to SNAP Rebuild help files to be Windows Vista combatable. Add steam lift for SAGD producers. Confirm multi-stage fracture transient treatment in complex wellbores. Formalize relationships with Weatherford (jet pumps) and Exxon (Gas Lift).

Near-term Plans

SLIDE 19

Tools for Evaluation : A review of the SOS Software

Formalize business systems for managing non-client (= paying) users. Continue to build user base to increase ability to maintain and organically grow program functionality.

Long-term Plans
