OHM APPRAISAL

OHM APPRAISAL replaces multiple appraisal wells by mapping the lateral extent of an oilfield.

Advanced 3D surveys are designed to identify the lateral extent of hydrocarbons within a reservoir. Used after a positive exploration well, or after an OHM RESOLUTION survey,OHM APPRAISAL acquires a dataset suitable for full 3D analysis using OHMVision INV3D.

OHM APPRAISAL survey layouts are carefully calculated to maximize the coverage of the reservoir whilst ensuring maximum constraint through the use of multiple field components. In addition to the source lines and receiver arrays, the source transmission waveform is optimized for each reservoir.The source frequency and waveform are designed prior to the survey, based on 3D forward modelling simulations, incorporating field specific a priori information.

OHM offers unrivalled capabilities in 3D Controlled Source Electromagnetic Imaging (CSEMI) inversion, along with over 20 years of top level experience in acquiring and interpreting Full-E-Field surveys. OHM applies this experience and capabilities to turning OHM APPRAISAL surveys into 3D maps of reservoir, saving multiple appraisal wells.
