Seismic Reservoir Characterisation
Well and seismic data can be integrated to predict lithology and fluid, quantify reservoir properties, identify leads and help risk prospects. This course provides an introduction to the concepts and application of quantitative seismic interpretation including statistical rock physics analysis and modelling.
This course discusses reservoir characterization as it applies to all stages of oil and gas field activity: from reconnaissance, through exploration and appraisal, to focused reservoir characterization during field development. As more data becomes available the options for QI increase. Workflows should be fit-for-purpose given project objectives and data availability. Reservoir characterization methodologies spanning qualitative attributes, inversion, probabilistic lithology and fluid predictions and the quantification of reservoir property distributions are presented. These include well log calibrated amplitude and AVA interpretations, stack rotations, and deterministic and stochastic inversion. The importance of petrophysics and rock physics calibration as a foundation for all of these methods is highlighted.
The course also discusses seismic velocity modelling: the smooth merging of multiple 2D and or 3D velocity fields into a consistent 3D volume; and the calibration of seismic velocities to well data for accurate time-to-depth conversion. Depth conversion of seismic data and derived properties are important for facilitating well planning and field development decisions as well as for quantitative result interpretations.
The course would benefit all technical staff in exploration and development who are interested in determining formation properties through seismic and log data integration.
Dr Sagar Ronghe specialises in Quantitative Interpretation integrating wireline and seismic data. He has over 20 years of experience in seismic reservoir characterisation. Sagar is a Geoscience Manager with DownUnder GeoSolutions, based in Perth, Australia. His educational qualifications comprise a Bachelors in Geological Oceanography from the University College of North Wales, UK, a Masters Distinction in Petroleum Geology and a PhD in Geophysics, both from the University of Aberdeen, UK. He began his career in 1996 as a Lecturer in Geophysics at the University Brunei Darussalam. In 2002, he joined Fugro Jason as a Project Geoscientist based in Kuala Lumpur, relocated to Perth in 2007 and was appointed Regional Technical Manager for Fugro Jason in 2012. Sagar has been with DownUnder GeoSolutions since 2013.
Participants should have basic knowledge of seismic data and well logs.
