POWELTEC team has an experience of more than 100 field trials performed in very different environments and can thus provide a full design of operations.
POWELTEC laboratory equipments and methods have been optimized within an internal R&D activity. Basically, the design of a POWELTEC treatment (WSO, CC, SC) or of a Polymer Flood pilot requires the optimization of the formulation via bulk tests and the evaluation of the actual performances in the reservoir via core-flood experiments.
A range of laboratory equipment is available to check polymer/gel solution properties and stability under reservoir conditions (rheometers, analyzers, glove box)
The second phase of the laboratory study consists of coreflood experiments to determine polymer properties in the reservoir conditions. This requires having specific coreflood equipment dedicated to polymer and chemical EOR. The coreflood program aims at delivering the full polymer performance data set which will be used further on in the reservoir simulations.
Seven core-flood set-ups can be used to perform flow experiments in actual reservoir conditions (up to 150°C). Polymer performance is checked by its selective effect on water/oil or water/gas permeability. Mobility/Permeability reduction can be determined in a broad range of injection rates.
The set-up enables measurement of dynamic polymer adsorption and Inaccessible Pore Volume (IPV).
The integrated simulation service offered by Poweltec is aimed to the design of Water Shut-Off, Conformance treatments and Polymer flood projects. Based on reservoir simulation studies, this work consists on the following steps.
POWELTEC team has an experience of more than 100 field trials performed in very different environments (onshore/offshore, oil/gas wells, light/heavy oil, vertical/horizontal wells, etc.) and can thus provide a full design of operations, i.e. product selection and delivery, definition of surface handling facilities, operational program, on-site assistance (quality control measurements for the solutions prepared in the field & support to the operation manager).
WSO treatments using RPM polymers do not require mechanical tools for placement and are thus very cost-effective. However, a careful control of the quality of the solutions pumped downhole is mandatory to avoid any risk of well plugging. Concerning Polymer Flood project, the main risk of failure lies often in the poor control of polymer dissolution and handling units. POWELTEC experts can assist the company in equipment selection and pilot start-up to avoid unexpected operational problems.
Poweltec can provide expertise to the companies under different forms:
Poweltec independency enables performing this expertise without any commitment with manufacturing or service companies.
Different families of products with low environmental impact have been designed for both Water Shut-Off & Conformance Control:
