... aquifers formations. Due to long shutdown period on subject wells, these wells are encountered with high rate of CCA phenomena among other wells. An immediate mitigation action is required to resolve the issues by applying rig workover operation which is considered highly cost approach with low success...

... to develop and evaluate the completion strategies for the subject well. First, a fieldwide 3D static geologic model was constructed using the aforementioned data to determine the best reservoir and completion qualities of the Vaca Muerta formation. Next, the model was used to develop the completion strategy...

During the planning of a well in which Pay Zone Steering is to be used, the overall drilling objectives are addressed and then incorporated into a basic earth model for the subject well. The expected log responses for the well are computed with forward modeling software. Once...
