1 好朋友! U.S. CO 2 Enhanced Oil Recovery and Residual Oil Zone Storage Update and Recent Advancements Third International CCUS Forum Beijing, China March 30, 2016 Dr. Bruce HILL Chief Geoscientist -- Ming SUNG Chief Asia Representative Clean Air Task Force, USA

2 2 Recycled CO2 MPZ: Main pay zone traditional oil and gas production OWC ROZ: Residual Oil Zone

3 What EOR Looks Like. Whiting Petroleum Co., North Ward Estes Field, Texas Control Room Injection Well N CO 2 Main Separation & Compression (+ NGL Removal) Recycled CO 2 R CO 2 Lift/Production Satellite Manifold & Separator Gas & Fluids Satellite Oil Tank O&G Oil Photos: B Hill, CATF.

4 4 ROZ ROZ ROZ : Marks where residual oil zones have been mapped. US EOR Survey, Kuuskraa (OGJ, April 2014)

5 5 Steady 3-Decade Growth of US CO 2 EOR Ref: Oil & Gas Journal Biennial Production Volumes (Mar of even Number Years)

6 What about the Slowdown? CO 2 EOR Project Growth Continued During A Decade of Low, Flat Oil Prices

7 What is New in CO2 EOR? First EOR Storage Project Approved by EPA: Oxy s Denver Unit in West Texas Permian Basin. Next Generation Methods: For example-- Utilization of greater volumes of CO2 (1-1.5 HCPVs) with reservoir surveillance and improved sweep conformance. Horizontal drilling next. ROZ Commercialization: Naturally water flooded zones with remaining oil saturation below the main pay zone (MPZ). Recoverable with CO2 EOR methods. Greenfield ROZ: ROZ Production where there is no main pay zone oil production. DUROZ: Depressure Upper ROZ to stimulate O&G ROZ 7 Photos: B Hill, CATF.

8 Oxy Denver Unit Storage Project MRV Plan Approved by US EPA Dec. 2015

9 9 ROZ is real. Now in Commercial Production Phase 6 CO2 EOR ROZ Project Starts No. of Project Starts Observation Phase Demonstration/Observation Phase Seminole and Wasson (Denver Unit) (Bennett Ranch Unit) Commercial Deployment Phase Deployment Phase Year (Biennium)

10 10 Update on ROZ Development -as of February individual projects underway in 8 different fields. Deployment of ROZ floods continues despite low oil prices. All ROZ projects are in the Permian Basin using CO 2 EOR technology to flood the ROZ of the dolomitic San Andres Formation. K-M is successfully flooding a Greenfield, that is, a pure ROZ where no main pay zone (MPZ).

11 11 ROZ Fairway Map West TEXAS Permian Basin Fairways are mapped petrogenetically (geologically) related ROZ formation zones. Oil resources may occur in these fairways regardless of whether there is a MPZ.

12 DRAFT June 11, 2015 San Andres ROZ Fairway of Yoakum and Gaines Counties (ARI) This two-well cross-section illustrates the characteristics of the San Andres ROZ Well No. 1, has a thick, well-developed Main Pay Zone (MPZ) with a higher quality Upper ROZ (ROZ 1 ) Well No. 2, in the ROZ fairway has a thin zone of higher oil saturation at the top of the ROZ and a higher quality resource interval in the Lower ROZ (ROZ 2 ).

13 What is a Greenfield ROZ? X NO MPZ! OWC Miscible CO2 Production Only Below the Oil Water Contact

14 K-M Tall Cotton: First US Greenfield ROZ. Phase 1 Initial Production 11/2014 to 1/ to 730 BOPD February 2016 Oil Conversion to Metric: ~ 7 bbls/tonne

15 Kinder Morgan Tall Cotton CNPC/ RIPED Flooding Tour 2015

16 16 Depressuring the Upper ROZ (DUROZ): Expanding CO 2 EOR and Storage Opportunities. Initial Production Strategy Which Also Increases CO 2 Storage Potential for CCUS -- Leaves over 90% of the Residual Oil Behind for CO 2 EOR Builds out Infrastructure Needed for CO 2 EOR While Providing a Commercial Project

17 New Resource: Exploring for ROZ A Step-by-Step Guide 17 To help determine for an operator: If a Residual Oil Zone (ROZ) might below their field. ROZ outside of their field. ROZ properties to identify zones that might be exploited with EOR methods. FOR MORE INFORMATION CONTACT: STEVE MELZER AT Melzerls@aol.com Dr. Robert Trentham at Trentham_R@utpb.edu

18 This is about CCUS! ROZ and Next-Generation EOR Will Require and Store Billions of Tonnes of CO2. The 4 Counties of the Permian Basin alone will utilize and store 7 GT CO2. To Produce all the Continental US EOR, an estimated 33 GT will be needed Source: Kuuskraa, ARI (Rice University, October 5, 2015): Increasing the Size of the CCUS Prize: The Potential and Economic Viability of Storing CO2 and Producing Oil from the ROZ of the Permian Basin Greatly Enhances the CCUS Option

19 The Full Potential of US CO2 EOR Cannot Be Realized Without Captured CO2. Currently, there is Limited CO2 Supply in the West Texas Permian Basin. In China, Where There is No Naturally Sourced EOR will Require 100% Captured CO2.
