Drilling Solutions for Improved Recovery

Programme 2 addresses optimal well placement and well design for improved recovery of oil and gas.

High capacity transmission and real-time interpretation of drilling and seismic data, in combination with work processes for updating of earth models, will enable improved safety and optimisation of the well placement and design while drilling.

Project 1: Deep imaging, geo-steering and flexible earth modelling during drilling (2011-16)

Motivation
High resolution deep imaging and geo-steering has the potential of highly improving oil recovery by being able to optimise the well placement in the reservoir. In addition, the increased amount of measurements available in real time while drilling with wired pipe opens new possibilities for optimisation of well placement.  This requires effective interpretation, integration and utilisation of the new information within the timeframe set by the on-going drilling operation.  However, current three-dimensional earth modelling tools have limited capabilities for effective integration of newly acquired information.  Model modifications are complex and labour intensive, and the time needed for updating the model often exceeds the time available during drilling operations. This is a large drawback for decision-making processes that require the most current and precise information.

Main objective
Develop and demonstrate improved workflows for geosteering. This includes:
  • Developing methods and algorithms for deep imaging (imaging ahead and around the wellbore) and geo-steering to improve well placement and geometry, reduce downhole and geological risks
  • Supporting decisions for optimal well placement by the development of methods for effective real-time three-dimensional earth model management
