Choosing the right product and technology for individual reservoirs and applying it at the right time is extremely important in maximizing oil recovery. ZL was established in 1995, with strong focus in polyacrylamide R&D and manufacturing for enhanced oil recovery industry. We use our expertise and on-site experiences to help our customers evaluate the reservoir characteristics to design the most cost effective program. Our lab work, pilot testing and application methodology will help bring success to full field implementation.
The complexity of the geology and other characteristics of oil reservoirs (such as temperature, salinity and hardness of the water in the reservoir) mean that different Polymer products are required for different reservoirs. It is important to choose the suitable product to ensure technical success while minimizing the cost of the chemicals and operation costs to ensure both technical and economical success. Each of polymers’ chemical property is linked to economic and technical success of a polymer flooding projects. For example, polymer’s ability to dissolve under target injection water directly linked to the facility design and the injectivity of polymers over time; polymer’s ability to maintain high viscosity in situ over time tells the real mobility ratio you will gain throughout the reservoir; polymer bulk viscosity, shear resistance, adsorption, structures, hydrolysis degree etc are all the parameters we look at and work with our customers to understand the chemistry and to ensure a successful polymer flooding project.
We work with our customers closely to evaluate their reservoir conditions. We believe only suitable polymers are able to maximize the oil recovery. Please contact one of our Reservoir engineer for information about polymer properties and its indication for a successful polymer flooding project.
