This document was prepared for publication through American Society for Mechanical Engineers (ASME) and is intended for a gas industry reading audience.
In 2021 Paulsson, Inc. (Paulsson) partnered with Pacific Gas & Electric (PG&E) and California Energy Commission (CEC) to research, develop, manufacture, deploy, and operate a robust, cost-effective, and all-optical Underground Gas Storage (UGS) reservoir surveying and monitoring system. Enhanced Distributed Acoustic Sensor (EDAS) and Distributed Temperature Sensor (DTS) data have been recorded, processed, and analyzed for more than 6 months.

​
As part of a significant seismic technology effort, the BP Wamsutter Seismic Integration team conducted two extensive field trials during
2006 and 2007- a surface seismic field trial and a borehole seismic field trial.
Although 3D seismic imaging, based on surface sources and
receivers, has been the primary tool used for geophysical
reservoir monitoring to date, vertical seismic profiling (VSP)
has characteristics that make this technique particularly suitable
for time-lapse surveying.
Björn Paulsson, Martin Karrenbach, Paul Milligan, Alex Goertz, and Alan Hardin of Paulsson Geophysical Services, with John O’Brien and Don McGuire of Anadarko Petroleum Corporation explain why recording multi-component seismic data using receivers positioned deep in the earth, and closer to the target zone, can overcome many of the limitations experienced by surface 3D seismic methods.
Two crosswell seismic surveys were conducted at Chevron
Canada’s Oil Sand Lease 49 (Steepbank) located about 60 km
northeast of Fort McMurray, Alberta. This is the site of the
HASDrive commercial pilot project in which steam is circulated
through a horizontal well in order to preheat the tar sand
prior to conventional steam injection. The objective of the
crosswell survey was to define the geology and to monitor the
movement of the injected steam as part of the HASDrive
evaluation. The first survey was conducted 25 September-6
October 1991, just prior to steam injection. The second was
acquired 7-14 January 1992, after 72 days of continuous
steam injection.
Cross-well seismic tomography is developing into an important tool for reservoir management, and within the last few years there have been some notable advances in our understanding its imaging capability.
A cross-well seismic tomography survey was conducted jointly between Chevron and Texaco in the Texaco portion of the McKittrick oilfield. The McKittrick oil field is shallow, less than 1300 feet, and contains low gravity oil which is perched above the water table.
Today it is common that 60 to 70 percent of the mobile oil is left in the ground when an oil reservoir is considered economically depleted (DOE, 1986). The large percentage of mobile oil left in the ground is due, in part, to macroscopic inhomogeneities in the oil reservoirs.
The behavior of a quartz monzonite rock mass subjected
to a thermal load from emplaced canisters with
electric heaters simulating high-level nuclear waste was
monitored by a cross-hole seismic technique in a drift
340 m below the surface in the Stripa mine facility in
Sweden.
Tomographic imaging techniques were applied to two
crosshole data sets to determine the velocity structures
and the reliability and resolution of the algorithms on
real data. The experiments were carried out at the Retsoff
salt mine in New York and at the underground
radioactive waste study site at the Stripa mine facility in
Sweden.
