The benchmark for petrophysics, rock physics, facies analysis and statistical mineralogy. Collaborative multi-well log analysis made easy for better drilling decisions.
We integrate log, core/cuttings and production data to obtain physical properties such as mineralogy, porosity, permeability, and fluid saturations. The goal is to assess accurate reservoir rock and fluid properties at well locations to be integrated with seismic data and its derivatives.
Petrophysical conditioning of well log data is performed to remove artifacts in the data caused by borehole or other problems during logging. Well logs are conditioned in entirety, from surface-casing to TD, and elastic logs (VP, VS, and density) are extended to the surface for accurate seismic integration.
Data issues identified and corrected may include, but are not limited to:
Rock physics modeling requires an understanding of underlying geology, rock and fluid properties, and seismic attributes associated with AVO, including those generated from seismic inversion.
A common goal of rock physics is to establish relationships between rock properties measured in the laboratory or inferred from well logs, to the seismic response, often in the form of elastic moduli (such as Young’s modulus). Petrophysics is a natural bridge between laboratory (core-scale) and seismic data
Conditioned well log responses are calibrated to rock measurements, which can then be directly up-scaled to seismic resolution, or indirectly used to add detail or constrain seismic results through the use of statistical methods.
Rock physics modeling relates changes in reservoir properties, such as pore-fluid saturation, lithology, porosity, pressure and temperature, to seismic signatures. This allows the use of seismic data in the prediction of reservoir quality and production drivers, including post-mortem of poorly-performing wells and dry holes. These relationships are also used to understand and improve interpretation of seismic attributes and inversion results. Examples include Gassmann fluid-substitution, which provides insight into hydrocarbon effects on seismic attributes through forward models, and lithofacies classification using multivariate analysis of elastic attributes common to inverted seismic and well logs. Because of its close relationship to geomechanics, rock physics can also inform geomechanical workflows seeking to model brittle-failure of rocks during well completions.
