Research Partnership to Secure Energy for America The purpose of the phase behavior study is to determine the surfactant composition and salinity that provides the lowest IFT. Two phase (surfactant-brine) and three phase (Oil-brine–surfactant) behavior will be observed, using brines at various salinities ranging from 0 to 1M, and different temperatures from 20 to 120˚C. Na 2 CO 3 and NaCl will be used to change salinity in different cases. Subtask 4.5 – Interfacial tension tests The purpose of this task is to measure IFT to help optimize the formulation for the oil/brine/surfactant system. Optimal salinity is taken as the salinity of the system which gives the least IFT between the oil and the aqueous phase. Task 5.0 Numerical Simulation and Modeling of Imbibition The objective of Task 5 is to build a numerical model of the system will be employed to simulate the imbibition process. The model will be based on an isothermal system. Four components will be considered: hydrocarbon, water, surfactant, and salt. The SUBCONTRACTOR shall first build an ideal model to match results of the imbibition and core flooding experiments. The SUBCONTRACTOR shall then conduct a field-scale numerical simulation model to predict enhanced oil recovery. A field-scale numerical model will be set up to estimate oil production in reservoir-scale matrix blocks. Where possible, the field-scale model will use reservoir properties and dimensions based on information derived from industry contacts, although certain ideal assumptions may be necessary (homogenous matrix, perpendicular and infinitely permeable fractures, etc.) Subtask 5.1– Ideal model building The purpose of this task is to scale the laboratory results with the ideal numerical model. The model will be based on an isothermal system. Four components will be considered: hydrocarbon, water, surfactant, and salt. Subtask 5.2– Field-scale numerical simulation prediction The purpose of this task is to estimate oil production in reservoir-scale matrix blocks. The field-scale model will use reservoir properties and dimensions based on information derived from industry contacts, although certain ideal assumptions may be necessary (homogenous matrix, perpendicular and infinitely permeable fractures, etc.) Task 6.0 - Routine Reports and Other Activities Upon contract execution, SUBCONTRACTOR and other project participants should coordinate with the RPSEA Project Manager to plan and schedule the Project Kick-off Meeting(s). Monthly reports are due to RPSEA on or before the 7 th of every month. Report templates are provided by RPSEA on its website. RPSEA schedules progress meetings and SUBCONTRACTOR may be requested to provide a project presentation, as required. 09123-09 - University of North Dakota (WANG) Appendix 1 30
Research Partnership to Secure Energy for America SUBCONTRACTOR may be asked to participate in person, or via web meeting at the RPSEA Project Manager’s discretion. Planning should be done for a Houston based meeting although there may occasionally be a need to meet at SUBCONTRACTOR‘s office. A final project presentation will also be expected following Project completion. REQUESTS FOR INFORMATION DOE periodically will request information from SUBCONTRACTOR through RPSEA for the purposes of estimating or evaluating the benefits of the program. SUBCONTRACTOR shall provide information requested by RPSEA to support DOE’s quantitative estimation of program benefits. C. Responsibilities Of Subcontractor 1. SUBCONTRACTOR shall furnish the necessary qualified personnel for the implementation of the tasks set forth in B. above. D. Deliverables of the Defined Effort All Monthly Reports and Deliverables must be uploaded to the RPSEA SharePoint web site. Monthly Reports and Deliverables are due by the 7 th calendar day of the month. The hyperlink to access the SharePoint site and “Instructions for using and Uploading Invoices, Reports, and Deliverables” is: https://sp.rpsea.org/RPSEA_PM_Action. SUBCONTRACTOR shall supply RPSEA with the name, email address, and phone number for a point of contact (POC) responsible for uploading. SUBCONTRACTOR shall provide the POC within 10 business days from the effective date of the subcontract. RPSEA will have the SharePoint site activated for SUBCONTRACTOR within 20 business days from the effective date of the subcontract. Reports and Deliverables sent in any other manner will not be acknowledged and will be rejected. 1. Project Management Plan - due within thirty (30) days of the Project kick-off. 2. Technology Status Report - due within thirty (30) days of the Project kick-off. 3. Technology Transfer Plan - due within thirty (30) days of the Project kick-off. 4. SUBCONTRACTOR will construct an open-access project website within 6 months (180 days) of the project kick-off date. It should include project information, progress reports, and other pertinent information derived from the project and should be maintained throughout the project period. 5. SUBCONTRACTOR will work with the PTTC or other appropriate producer organizations to present at least two talks on study results at meetings or workshops that target the regional producers by the end of the project. 6. SUBCONTRACTOR will publish at least one relevant article in a trade journal that specifically targets producers by the end of the project. This article should be accepted for publication by the end of the project. 09123-09 - University of North Dakota (WANG) Appendix 1 31
