As the demand for energy worldwide increases, the oil and gas industry will need to
increase recovery from unconventional gas reservoirs (UGR). UGRs include Tight Gas
Sand (TGS), coalbed methane and gas shales. To economically produce UGRs, one must
have adequate product price and one must use the most current technology. TGS
reservoirs require stimulation as a part of the completion, so improvement of completion
practices is very important. We did a thorough literature review to extract knowledge
and experience about completion and stimulation technologies used in TGS reservoirs.
We developed the principal design and two modules of a computer program called Tight
Gas Sand Advisor (TGS Advisor), which can be used to assist engineers in making
decisions while completing and stimulating TGS reservoirs. The modules include
Perforation Selection and Proppant Selection. Based on input well/reservoir parameters
these subroutines provide unambiguous recommendations concerning which perforation
strategy(s) and what proppant(s) are applicable for a given well. The most crucial
parameters from completion best-practices analyses and consultations with experts are
built into TGS Advisor’s logic, which mimics human expert’s decision-making process.
TGS Advisor’s recommended procedures for successful completions will facilitate TGS
development and improve economical performance of TGS reservoirs.
