Underground Gas
Storage
FAW has developed and provided
testimony relating to underground gas storage to various governing
organizations. Our studies have been used in litigation and to support IRS
issues.
In addition to the above, FAW's
principals have been involved in numerous other studies related to gas storage
or in areas which directly apply to underground storage. A brief discussion of
some of these are listed below:
1. Screening and preliminary
design studies of potential gas storage have been performed for several gas
storage companies.
2. FAW provides ongoing
reservoir engineering support to several gas storage companies. This has
included inventory verification, deliverability, working/base gas ratios,
non-recoverable base gas and gas migration studies.
3. Design and evaluation of
aquifer storage reservoirs. These studies included making "history
match" estimates of residual and critical gas, gas bubble growth and
deliverability estimates as constrained by water movement and wellbore and
surface system flow constraints.
4. In 1985, FAW, in competitive
bidding, secured a multi-year project from the Gas Research Institute. The
project scope is to develop an understanding of the production of natural gas
that would not be produced by conventional methods from underground gas
reservoir formations unless large amounts of water or brine are produced with
the gas (Co-Production). This project is ongoing.
5. Simulation studies of
water-drive gas reservoirs including the effect of aquifer size and strength
and rate sensitivity studies of gas recovery.
6. Comprehensive analysis of the
production of natural gas from Devonian shales, including a definition of the
process, study of well testing procedures and test analysis techniques and
sensitivity analysis of various reservoir and stimulation parameters.
7. Analysis of
geothermal/geopressure well tests including a sensitivity study of the effects
on production and ultimate recovery of pressure dependent rock properties.
8. Studies of the gas from coal
process including all aspects of production from the screening of prospects
through the conceptual design phase as well as full field developments
including the drilling/completing and testing of wells.
9. Analysis of tight gas
reservoirs including single well analysis as well as interwell interference.
Many of these single well studies have included the pre and post reservoir
analysis of hydraulically fractured wells. In many cases, the fracture design
was also made.
10. Gas utilization and
production studies requiring the application of a wide range of technology to
allow a complete analysis of multiple reservoirs under alternate development
programs, and integration with surface facilities as pipelines, gas plants,
compressor and end users.
11. Single well coning studies
including both gas/water and oil/water systems.
12. Reservoir studies of
water-drive oil reservoirs and the design and implementation of waterflooding.
13. Provided project management
to industry funded (multiple companies), DOE and ERDA contracts, as well as
large reservoir management studies for both operating companies and foreign
governments.
14. Property appraisals and
economic evaluations for banks and operating companies.
15. Compositional studies of
volatile oil and gas condensate reservoirs including gas cycling and
vaporization studies.
