Fekete’s abilities in gas gathering system optimization have been recognized as a truly unique and valuable service to the oil and gas industry. Using our F.A.S.T. Piper™ software, Fekete’s engineers are able to build a model of a gas gathering system that includes the surface gathering system, wellbores, and reservoirs.
On the surface side, F.A.S.T. Piper™ has the capability to model complex pipeline systems with actual sizes, routes and elevation changes along with various facilities such as compressors, separators, offtakes and intakes. Wellbore modeling allows the engineer to analyze wellhead and sandface deliverability and determine if and when a well is capable of lifting liquids to surface. In addition, tank-type (volumetric depletion), transient, water-drive, connected, geo-pressured or coalbed methane reservoirs may be incorporated into a F.A.S.T. Piper™ model.
After building the model, Fekete personnel can conduct a field tour to obtain accurate flowing pressures and investigate compressor operations. This provides a snapshot of system performance against which the model is calibrated in order to represent actual field conditions. After calibration, future production forecasts can be generated with “what if” scenarios, including compressor changes, new well tie-ins, debottlenecking, accelerated recovery and more.
Projects
Fekete’s engineers can build a model of a gas gathering system including:
- Actual pipeline sizes, routes and elevation changes
- Well deliverabilities
- Multiple zones with different pressures, reserves and depletion
- Multiple delivery points
- Different gas compositions
- Production forecasting that is more accurate than decline analysis
- Aquifer support or communicating reservoir modeling for material balance
