HOUSTON -- December 14, 2012

RSI is pleased to announce the launch of its ERA research project, which will
commence in January 2013. Phase one of the study will be focused in the
Barents Sea. The project will build on RSI’s existing atlas of rock physics
and seismic responses, and will use well log, CSEM data and rock physics
modeling to develop a better understanding of regional resistivity and
anisotropy trends. The research project will examine the underlying causes of
these trends and develop methods to predict anisotropy from common well log
measurements, extending the proven success of the EM method to a wider
regional application. Further phases will extend this work into additional
hydrocarbon basins including Gulf of Mexico, West Africa, the Malay Basin and
onshore unconventional plays, with emphasis on both acoustic and electrical

Four companies including Statoil and Electromagnetic Geoservices ASA (EMGS)
(who will contribute CSEM and anisotropic inversion data from their
comprehensive Barents Sea data library) have confirmed their participation,
and a number of other companies have expressed strong interest.

Richard Cooper, RSI’s CEO commented: “An understanding of anisotropy, both
acoustic and electrical, is key to the successful application of seismic and
non-seismic surface geophysical measurements in a number of key play types,
such as well-planning in deep-water sub-salt targets, CSEM for offshore
reservoir characterization, and sweet-spot detection in shale plays. Although
the industry has developed imaging and inversion algorithms to accommodate
anisotropic parameters, there is a need to develop companion methods to
independently validate these parameters using well-log data and rock-physics
models. The ERA project is designed to deliver this understanding.”

Stated Dr. Lucy MacGregor, RSI’s Chief Technology Officer: “Controlled source
electromagnetic (CSEM) survey data provides valuable information on the
resistivity of the sub-surface, and increasing volumes of these data are now
available. Additional value of these data can be realized by interpretation
within a regional resistivity context, and calibration, where possible, to
well log data using a robust rock physics framework. To do this requires
analysis of regional resistivity and anisotropy trends, and investigation of
their underlying cause.”


RSI is an independent geoscience consulting firm offering quantitative
reservoir characterization with the goal of reducing exploration drilling risk
and optimizing reservoir appraisal and development plans. The Company is an
industry leader in the interpretation and integration of seismic data with
well log, CSEM and MT data, and uses advanced rock physics methods combined
with sophisticated geologic models to deliver robust and reliable predictions
of reservoir geometries and properties to our customers.
