CO2 Conference Week


“It’s where the field and office come together to make things happen” 

Once again, the Conference Committee for the 2017 CO2 Conference Week (Dec 4th-7th, 2017) brought the field case histories to the CO2 & ROZ Conference venue in Midland, Texas.  As in the past, the Conference included the annual EOR Carbon Management Workshop, a full day seminar, the annual CO2 Flooding Conference and, this year, includes the ROZ (Residual Oil Zone) theme, and a field trip.

Since 1994, the conference has continued to expose both new ideas and field-tested practices to the CO2 business community and now the Residual Oil Zone reservoir depressuring companies all the while providing scholarship funding to help the industry staff for the future. The conference has grown to spread out over nearly a full week and to include a CO2 capture, utilization and storage (CCUS) workshop, a specialized subject seminar/short course, as well as the ever-popular CO2 enhanced oil recovery and Residual Oil Zone case histories.  Over the last ten years, the Conference has been the leading avenue for the public vetting of the exciting area of residual oil and transition zones which are becoming an important target for both EOR and horizontal wells and has attracted international attendees (and a few international speakers with ROZ examples) wishing to hear more about this exciting new area.

This year’s flooding conference began on Monday, December 4th and continued thru Thursday (7th) at the venue of the Horseshoe Facility in south Midland. The events led off with the annual Carbon Management Workshop reviewing the latest in CO2 capture and demonstration projects, future plans, legislative initiatives, and policy matters related to carbon capture, utilization and storage (CCUS). We had the CO2 week welcoming reception that evening. Then, starting at 8:00 am on Tuesday, the conference plans examined in detail the Residual Oil Zones (ROZs) exploitation underway in the Permian Basin with a look at both the CO2 EOR projects and the horizontal well utilization spreading throughout the Central Basin Platform and onto the North Shelf. Much happened in the year since the previous conference.  The new estimate is that nearly 20,000 bopd are now coming from the ROZ greenfields (no overlying main payzone) in addition to the 175,000 bopd coming from CO2 EOR in the main pay zones, transition and ROZs.  The Conference devoted an entire day to the seminar ending with the popular conference reception sponsored by several key sponsors and the Permian Basin Section of the Society of Petroleum Engineers that evening. The reception was held in a new venue; the confectionary called Susie’s South Forty near downtown Midland, Texas, at the heart of the excitingly active Permian Basin region of the U.S.

The Wednesday event was another full day of presentations at the ever-popular EOR and ROZ case history theme sessions. The sessions opened with presentations that featured updates on the new developments in and the status of CO2 floods in both the Permian Basin and elsewhere. The Thursday afternoon session provided the reservoir case histories including some special speakers regarding the horizontal well depressuring projects.   The speakers again presented their newest field-tested concepts, ideas and best practices, along with discussions of business aspects of their projects during the talks.

The activity following the Wednesday session was a full-day field trip on Thursday.  The trip went to the vertically flooded Wellman field and its modern recycle and NGL recovery plan also included a side trip to western Yoakum County where Steward Energy guided the attendees through an area with over 50 horizontal wells drilled in the past three years in the San Andres formation ROZ there. The trip also took the occasion to drive by Kinder Morgan’s Tall Cotton Greenfield ROZ CO2 flooding project on the way back to Midland and a quick syop and viewing of the impressive Seminole San Andres Unit CO2 Recycle and natural gas liquids removal plant. The buses returned to Midland at 4:30 and concluded the Conference week activities.

The presentations from the Monday Carbon Management Workshop and Wednesday Theme Sessions are available as free downloads under the presentation tab.  The Tuesday Seminar is available for a nominal fee download in the Shortcourse/Seminar section of this website.
