Hybrid Rotor Compression for Multiphase and Liquids-Rich Wellhead Production Applications

2011 Small Producer

Project Number: 11123-15 Project Status: completed
Start Date: Jan. 15, 2013 End Date: Sept. 30, 2014
RPSEA PM: Charlotte Schroeder Principal Investigator: Jeremy Pitts
Subcontractor: OsComp Systems Inc.
Project Objectives:

The objective of this work is to develop OsComp’s hybrid rotor compression technology into a robust and commercially viable solution which can be used as a multiphase compression solution for wet gas applications in small producer environments. This is an R&D project intended to iterate upon the existing technology and optimize it for wet gas applications in a small package. The project’s objective is to prove that OsComp’s technology can work with wet gas streams at high efficiencies in a manner which will prove beneficial to small producers.  

The project begins with OsComp’s pre-existing technology being further tested and analyzed to inform the redesign of the system. The updated design will be built into a second generation prototype which will be tested in OsComp’s facilities under controlled conditions. Once OsComp’s engineering team has tested the compressor under controlled conditions and gotten a full understanding of its capabilities, a suitable field trial location will be selected in partnership with one of several producers with whom OsComp is currently in talks. A complete compression system will also be designed and built around the OsComp compressor to allow for field testing.

The project will then continue into field testing. OsComp’s initial compression package will be shortly followed by a second system placed at a different wellhead location. The OsComp team will seek to obtain as much as 12 weeks of runtime in the field from each of these compression systems. The objective of the field testing is to prove the viability of the system in an actual field environment and show preliminary results that the technology can be built into a commercially viable system.

Successful completion of the research and development described within this statement of work will lead directly into a field demonstration project which, upon successful completion, will ultimately lead to commercialization of the technology.

RPSEA PM: Kent Perry Principal Investigator: Phil Trump
Subcontractor: DaniMer Scientific, LLC
Project Objectives:

The primary objective of the project is to conduct field tests of the Novel Production Enhancement Process (NPEP) on actual small producer wells. A range of bottom hole temperatures, formation type and permeability will be explored to full investigate the applicability of the NPEP. The treatments will be considered successful if conducted in a timely and economic manner with little to no environmental impact, and result in a substantial increase in production.

Reduction of Uncertainty in Surfactant-Flooding Pilot Design using Multiple Single Well Tests, Fingerprinting and Modeling

2011 Small Producer

Project Number: 11123-24 Project Status: completed
Start Date: Jan. 15, 2013 End Date: July 17, 2015
RPSEA PM: John Terneus Principal Investigator: Benjamin Shiau
Subcontractor: The Board of Regents of the University of Oklahoma
Project Objectives:

Reservoirs containing very high total dissolved solids and high hardness make the design of a surfactant polymer (SP) flood difficult because surfactant tends to precipitate and separate under these conditions.  In the proposed approach different surfactant formulations are evaluated. These formulations incorporate cosurfactants and co-solvents which minimize viscous macroemulsions, promote rapid coalescence under Winsor Type III conditions, and stabilize the chemical solution by reducing precipitation and phase separation. The optimal surfactant formulations are further evaluated in one-dimensional sand packs and coreflood tests using Berea sandstone, reservoir oils, and brines at reservoir temperatures. Lab studies will be performed to check phase behavior and fingerprinting from different areas within a reservoir to explore the reservoir characterization.  Six multiple single well tests will be completed in two year periods to verify the robustness of new high TDS surfactant system and their effectiveness for mobilization of oil.  Recommendations for improving the chemical flood design and minimizing the risk will be made.

Pressure Prediction and Hazard Avoidance through Improved Seismic Imaging

2012 Ultra-Deepwater

Project Number: 12121-6002-02 Project Status: completed
Start Date: Sept. 18, 2014 End Date: Sept. 30, 2016
RPSEA PM: Gary Covatch Principal Investigator: William Barkhouse
Subcontractor: SEG Advanced Modeling Corporation (SEAM)
Project Objectives:

The objectives of this project was to (1) Deliver a benchmark simulated seismic dataset that will be used by industry and academic research institutes to investigate improved approaches for prediction of shallow hazards and deep over-pressured reservoirs; and 2) Reduce drilling risk – both safety and environmental – through improved pre-drill pressure prediction methodologies that are derived from iterative interpretations of the simulated dataset. 

The project evaluated and advanced current methodologies for pre‐drill pressure prediction from seismic data in the deepwater Gulf of Mexico. An industry research consortium will be established to provide a collaborative forum where industry experts will prioritize current challenges in the use of seismic velocity (and other seismic attributes) to construct pore pressure and hazards forecasts for well planning. The existing SEAM Deepwater Subsalt earth model will be modified to incorporate these challenges. A seismic acquisition plan will be designed that can evaluate the potential for current and future acquisition and processing techniques to provide improved estimates of abnormal pressure regimes. This seismic dataset will be developed through advanced computer simulation. The resultant benchmark dataset(s) is available to industry and academia for quantifying risk and uncertainty associated with velocity models derived from current and future state‐of‐the‐art in seismic acquisition, processing and imaging. A proposed methodology will be developed, with recommendations for further research, for assessing risk and uncertainty in pressure prediction from seismic.
