Field Development Planning & Production Optimization 

Field Development Planning

When you need to evaluate development options for a given field, upfront project scoping is key. We provide industry-leading net asset evaluations specific to your strategic planning needs by interpreting the details of different options and providing practical analysis of their merits.

Production Optimization

From Enhanced Oil Recovery (EOR) methods to Exploration Risk Assessments, we help optimize the returns on your upstream investments. Our expert team, in combination with our growing analytics capability, supports successful field development and production strategies.

Oil Sands Mining

Oil sands are a mixture of bitumen, clay, sand and water that can be found all over the world. The viscous nature of the bitumen at reservoir conditions generally prevents it from being produced from a conventional wellbore, but a small portion of these deposits in the Athabasca region of Alberta, Canada, are found at depths amenable to open pit mining.

Our market leading expertise in oil sands mining evaluations dates back to the 1980’s and has made us the trusted evaluator for all of the independently evaluated oil sands projects in Alberta.

We apply our experience to mineable oil shale projects outside of Alberta, where bituminous material is extracted from mined oil shale.
