The Path To Proven Results
Our Process at Esal
Screen, Labwork and Deploy
At ESal, we strive to provide much faster and less expensive analysis of reservoir wettability, as well as an assessment of the potential to control wettability by salinity, versus the industry average of 4-6 years and millions of dollars. Our business model means we can provide similar results in a fraction of the normal time and expense.
The most desirable outcome of a project is to assess and alter the in-situ wettability of the candidate petroleum reservoir to increase oil recovery, however even knowing that reservoir wettability is insensitive to salinity is valuable information for operations. We deliver this information to you by evaluating the relationship between salinity and wettability for the target reservoir.
There are three main stages in the workflow:
In order to provide an initial assessment, we developed an analytical screening tool based on hundreds of field and laboratory examples. Not all reservoirs have wettability that is sensitive to salinity and our screening tool saves time and money by eliminating marginal candidates.
After favorable screening results are observed, laboratory testing quantifies the current reservoir wettability as well as the salinity sensitivity.
Finally, the laboratory data is used to develop economic evaluations and serve as the basis to formulate chemistry specifications for the injected water.
We start with our proprietary screening tool to evaluate the rock, water, field and oil characteristics to produce a numerical score indicating the likelihood of successful wettability alteration. This tool’s algorithm is consistently refined and updated with new lab and field results to deliver better answers for customers.
Wettability modification doesn’t work in every reservoir, so this stage will confirm if Engineered Salinity is right for you and help reduce any project risk.
If the screening results are positive, our next step is lab testing.
This stage includes:
At this point in the process, our lab work has clarified how much oil can be recovered, including reversing lost recovery, further reducing your risk and maximizing your reward. Now, you can venture into the field with this unique knowledge and make the case concrete.
There’s no doubt about it. For all the screening and lab work, the oil and gas industry demands that execution in the field is what separates theory from living proof.
It’s a stage that couldn’t be more important. When it matters most, ESal continues our support into full deployment by identifying potential water sources to mix with produced water and water treatment options to achieve the optimal salinity level.
This stage includes:
Our work in the field will verify the reserves you have and can expect to have, shedding light on the additional years of reservoir life.
