DrilSeis™
The DrilSeis™ technology is an advanced seismic interpretation
tool that utilizes two independent approaches, the V-Based™
technique and the Q-Based™ technique, to determine shale
pore pressures and fracture gradients. Used in combination
with LithSeis™ technology, DrilSeis technology is the
most advanced seismic tool and service on the market, providing
true data integration for the petroleum industry. This proprietary
technology provides a comprehensive approach to project well
planning and operations to efficiently identify lithology,
porosity, and fluids, and to improve pre-drill estimates of
pore pressure and fracture gradient volumes. eSeis takes you
back to the rocks to enable multi-discipline
asset teams to immediately obtain benefit from seismic petrophysics.
V-Based™
The V-Based technique is the more traditional approach to
pore pressure prediction using seismic data. It is based on
an analysis of stacking velocities and uses state of the art
refinements and error-rejection routines. Shale pore pressure
is calculated by using established and calibrated relationships
between velocity, porosity, and pore pressure.
Q-Based™
The Q-Based technique is a patented technique developed by
eSeis to compute effective stress from frequency attenuation,
which can then be related to pore pressure. It is a fairly
straightforward calculation and large volumes of data can
be analyzed in a cost-effective fashion. The Q-Based method
and the V-based method complement each other as independent
solutions to the calculation of pore pressure.
