ResMap™ is ESG’s turn-key microseismic reservoir monitoring solution that delivers real-time feedback on the reservoir’s response to production related activities.

ESG deploys temporary, semi-permanent and permanent ResMap™ systems in oil and gas fields around the world to identify reservoir characteristics and provide continuous, detailed views of the reservoir’s response to production activities such as steam injection, EOR, waterflooding and CO2 injection. Operators are able to use this information to enhance their understanding of the reservoir’s performance, improving decision-making capability.

ESG’s ResMap™ is a turn-key solution. It encompasses:

* Feasibility studies to assess the underlying geological characteristics of the reservoir, and determine how they will affect seismicity. Dipole sonic logs, depth, temperature, pressure, lithological configurations and well layouts are all incorporated into a computer feasibility study to custom design a site-specific monitoring solution.
* Sensor arrays, remote monitoring stations, communications/satellite equipment, central computers and any customer-specific equipment are designed and built on-site at ESG’s manufacturing facility.
* ESG provides on-site installation and training services.
* Surveillance, data processing, interpretation and reporting services are conducted on a daily/weekly/monthly basis
* On-going service, maintenance, and upgrades are performed/installed as needed.

Applications

Reservoir Characterization: A microseismic monitoring program can be used for characterization purposes, providing asset teams with a deeper understanding of reservoir dynamics. Characterization applications include:

* Identification of fracture/fault sealing, which could prevent fluid injections from reaching targeted zones
* Imaging of fault re-activation or new fracture creation which could act as potential flow channels, influencing injection compliance
* Mapping areas of compaction to identify depletion zones and monitor caprock integrity.
* Combined microseismic and 4D VSP monitoring to provide enhanced velocity model.
* Use of microseismics in conjunction with 4D active source programs to fill in the time-lapse gaps between surveys and improve understanding of reservoir development over time

Thermal recovery optimization: ResMap™ allows operators to visualize the steam flood movement through the reservoir and model the thermal response. Operators are able to optimize thermal operations such as Cyclic Steam Stimulation (CSS), Steam-Assisted Gravity Drainage (SAGD) and Steamflooding in response to the information they receive.
Waterflood and EOR Optimization: Pressure changes and new fracture creation associated with fluid and EOR injection movements can be used to identify the waterflood front, giving producers feedback on their treatments. ResMap™ will also detect fluid movement along fracture networks or re-activated fault lines.

Monitoring for well casing and caprock integrity. Our systems have been deployed extensively in North America to characterize and detect microseismic events associated with well casing shear or caprock breaches. Operators can receive automatic real-time notification of any event that could be the precursor to a well casing failure or unplanned fluid migration.

Auxiliary Monitoring Capabilities

ResMap™ forms the backbone of a dynamic informational infrastructure and can easily support the integration of other auxiliary monitoring technologies to provide a robust platform for advanced analysis. Any ResMap™ monitoring system can be augmented with:

* Tiltmeters
* InSAR
* Downhole pressure sensors
* Downhole temperature sensors
