Stingray Launches FosarFocus System for Targeted Well
Zone Monitoring Applications
24 February 2011, Stingray Geophysical Limited, a leader in Seismic
Permanent Reservoir Monitoring (PRM) solutions to the upstream oil and gas
industry, has announced the launch of the modular, fibre-optic FosarFocus®
system to provide operators with a cost-effective and reliable solution to
targeted well zone monitoring requirements such as flood front and fracture
monitoring. By permanently installing a small, highly sensitive, broadband
FosarFocus 4C (multi-component) seismic sensing array on the seabed over
the target area, high dynamic range active and passive time-lapse data can
be acquired, enabling optimised production and hydrocarbon recovery
through improved reservoir management decision making.

For flood front monitoring applications, a FosarFocus array is installed
between injector and producer wells. Frequent repeat seismic surveys
provide intra-well reservoir time-lapse signals for dynamic reservoir model
updates. These updates provide critical information on the location of the fluid
front, pressure distribution and flow barriers or thief zones between injector
and producer wells. In addition, time-lapse seismic provides dynamic
information that can be used to identify which well zones are producing
effectively and when and where remedial action may be required.
For fracture monitoring applications, the FosarFocus system is deployed in
a cross or star pattern above the zone being stimulated. Micro-seismic events
associated with reservoir stimulation and detected by the array are
transmitted to a data centre for processing and updating of the reservoir
model. By providing the stimulated fracture geometry, azimuth, connectivity
and density, micro-seismic monitoring allows optimisation of the hydraulic
fracture operation, enabling faster hydrocarbon recovery and lower drilling
and completion costs over the life of a field. To facilitate optimal fracture
operation planning, an active seismic survey provides pre (and post)
stimulation information on the reservoir fracture network and stress field.
Stingray Geophysical CEO, Martin Bett, comments: “Real-time data is of great
value to oil companies seeking to make production management decisions
on, for example, changes to pump pressure or rate, or the proppant mesh or
modifications to well and completion design.
“By “listening with light” using a FosarFocus system, operators benefit from
understanding the location and distribution of fractures during a hydraulic
fracturing operation, helping them to better understand actual production
mechanisms and enhance recovery rates.”
Stingray Geophysical will be participating in the EAGE Workshop on
Permanent Reservoir Monitoring Using Seismic Data in Trondheim from
28 February to 3 March, 2011 and is a main sponsor of the event.
About Stingray Geophysical Limited
Stingray’s sole focus is providing the most advanced permanently installed
reservoir monitoring solutions to the global oil and gas industry. Founded in
March 2006 to commercialise a unique optical sensing technology for seismic
Permanent Reservoir Monitoring (PRM), Stingray enables operators to
address all their reservoir monitoring requirements by “listening with light”
using FosarFocus®, FosarDeep® and FosarField® sensing arrays to
accelerate production and increase their reserves while reducing cost and risk
through improved reservoir management strategies.
The core technology was originally developed for anti-submarine warfare and
security purposes by the UK’s defence research laboratories and is now being
exploited for advanced fibre-optic oil and gas seismic sensing applications by
Stingray under exclusive licence. Drawing upon a global network of trusted
partners and its Folio solutions services offering, Stingray delivers complete,
managed, integrated seismic PRM solutions from planning through to
processing and answer products.
