Novel Engineered Osmosis Technology: A Comprehensive Approach to the Treatment and Reuse of Produced Water and Drilling Wastewater

2010 Unconventional Resources

Project Number: 10122-39 Project Status: completed
Start Date: June 26, 2012 End Date: May 31, 2016
RPSEA PM: Sandy McSurdy Principal Investigator: Tzahi Cath
Subcontractor: Colorado School of Mines
Project Objectives:

The objective of this project was to investigate the osmotically driven membrane processes. They are processes that utilize osmosis as a driving force to extract water from highly impaired water while concentrating and minimizing the volume of the contaminated streams. The proposed research will advance the development and implementation of the forward osmosis, osmotic dilution, a novel ultrafiltration processes for treatment and management of well drilling, stimulation wastewater and produced water in many unconventional and conventional gas and oil fields. These processes have the potential to substantially reduce the overall costs and environmental impacts associated with gas and oil production.

Predicting Higher-Than-Average Permeability Zones in Tight-Gas Sands, Piceance Basin: An Integrated Structural and Stratigraphic Analysis

2010 Unconventional Resources

Project Number: 10122-47 Project Status: completed
Start Date: April 24, 2012 End Date: July 31, 2016
RPSEA PM: Skip Pratt Principal Investigator: Jennifer Aschoff
Subcontractor: Colorado School of Mines (CSM)
Project Objectives:

The research objective was to investigate depositional geometries and fabrics, such as fluvial channel architecture, channel orientation, accretion sets, sedimentary fabrics, grain-size and sorting, control the mechanical properties, lateral extent and thickness of beds and thus, the fractures within those beds. A better, and more integrated understanding of the structural, stratigraphic and diagenetic controls on tight-gas sandstones would allow the development of more sophisticated exploration and production strategies that would improve recovery and reduce environmental impacts by drilling fewer wells. The study area is within the Piceance basin of Colorado.

Game Changing Technology of Polymeric-Surfactants for Tertiary Oil Recovery in the Illinois Basin

2010 Small Producer

Project Number: 10123-03 Project Status: completed
Start Date: April 1, 2012 End Date: Oct. 1, 2014
RPSEA PM: Kent Perry Principal Investigator: Yongchun Tang
Subcontractor: Power Environmental and Energy Research (PEER) Institute
Project Objectives:

The objective of the proposed work in this project is to further develop polymeric surfactant (PS) technology as an alternative chemical EOR approach. This breakthrough technology that uses a single component instead of multiple components as in traditional Surfactant Polymer (SP) flooding has the potential of saving millions of dollars for mature field tertiary oil recovery operations. The typical oilfield reservoir conditions from the Illinois Basin will be used to test and evaluate the developing PS-EOR potential for this important mature oil field region.

Identifying and Developing Technology for Enabling Small Producers to Pursue the Residual Oil Zone (ROZ) Fairways of the Permian Basin, San Andres

2010 Small Producer

Project Number: 10123-17 Project Status: completed
Start Date: June 25, 2012 End Date: Dec. 31, 2015
RPSEA PM: John Terneus Principal Investigator: Robert Trentham
Subcontractor: The University of Texas of the Permian Basin
Project Objectives:

The objective of the project is to delineate presence and size of Residual Oil Zone (ROZ) resources in ROZ “fairways” in the Permian Basin of Texas and New Mexico. In the Permian Basin of Texas thick ROZ’s exist immediately below many oil fields productive from the San Andres dolomite. The zones can contain 20 to 40% residual oil in pore spaces. This oil cannot be produced by conventional production techniques, including water flooding. A ROZ CO2 flood is underway in the Seminole field and early projections suggest the project may recover 200-300 million barrels of additional domestic oil. In addition to examining the Texas resource in more detail, the study would develop technology for finding the higher quality portions of the ROZ resource recoverable with CO2 EOR directed toward the small oil producers within the Permian Basin and other ROZ basins within the U.S.

Project Objectives:

Development of a reliable, cost-effective real-time, riser integrity management system by closing technology gaps that include: availability of historical riser data for assessment of long-term integrity management of deepwater riser systems; on-board subsea equipment controls to detect anomalous behavioral modes and implement mitigation strategies; essential safety management system/software for riser system integrity data storage,  riser performance and user interface for on-ship and on-shore; and integrated deepwater drilling and production riser integrity management solutions encompassing hardware, software, processes, and people. The research was conducted in four stage-gated phases:

  • Design and development of a new concept with the assistance of key end-users to develop requirements for system design that will  build and test of a small scale subsystem, preliminary design for software and business process system integration (TRL1).
  • Development of a full-scale pilot for an integrated deepwater riser integrity management system, and a full-scale pilot test (TRL3). 
  • Development of a production plan for a commercially viable deepwater riser integrity management system that can be used for retrofit or new unit installation (TRL3-4).

The project is complete and it is anticipated that industry will carry the research to a commercialization stage (TRL5-6).
