PESA NSW Twilight Seminar 25th July 2017

Elks Pasture is not Moose Pasture!
CO2 Enhanced Oil Recovery (EOR) and Elk Petroleum’s Grieve Oil Field Rocky Mountains CO2 EOR Project

Presented by David Evans (COO, Elk Petroleum)

Elks Grieve Oil Field is situated in the prolific Northern Rockies Wind River Basin of Wyoming. First discovered in 1954 and shut in in 2012 it has been undergoing sporadic CO2 and water injection since 2013 with the aim of bringing the reservoir back to virgin pressure late in 2017 and production restarting Q1 2018.

CO2 EOR was first undertaken by Shell in the early 70’s in the Texas Permian Basin. Circa ~300kbbls/d in the US is produced via this method across 127 projects with a 95% success rate. Not having exploration and appraisal components CO2 EOR projects tend to be lower risk. There are often decades of extensive reservoir data and knowledge available before commencing an EOR project.

EOR production profiles are longer dated with shallower declines than primary production projects. Once a CO2 EOR project is operating, the ongoing operating expenditure on a project is generally low with fewer workovers and lower lifting costs. The challenges presented by CO2 EOR are in project selection and securing a low-cost (both CO2 procurement and shipping to site) and reliable CO2 supply.
