Enriching the Static Earth Model through a Near-wellbore Structural Modeling Workflow Combining all Horizontal Well Data

The static earth model is the centrepiece of field development, from initial reserves evaluation to well planning to production and recovery optimization. Also, the static model is most often the main source of information into the well placement pre-job model. However, while it was always agreed that the findings of a well placement job should be used to refine the original model, up until now, enriching the static model was not offered as a mature service by the providers of geosteering solutions and interpretation. This paper and presentation introduces a new workflow combining LWD information from borehole images and deep boundary mapping services (possibly from several wells in an area) into a near-wellbore 3D structural model supporting all available data. The 3D near-wellbore structural model workflow is an important contribution to workflows closing the loop from horizontal logging and well placement back to the reservoir model update.
