Daily Update - Mohammad Elkady - (June-03-2022)

1.  What did I do today?

I read SPE 186325 about Surfactant simulation using CMG STARS. Also, I searched for more tutorials about CMG STARS.  

2.  What did I find interesting/Work on? 

SPE 186325 - This paper address simulation of surfactant injection into waterflooded reservoir to increase oil recovery.

·      Relative permeability alteration due to IFT are represented in interpolation parameter named DTRAPW and DTRAPN, which is log value of critical capillary number for both wetting and non-wetting phase, respectively.

·      The primary objective of coreflood simulation history match is to obtain parameter required for pilot forecast such as

o   residual oil saturation reduction,

o   chemical retention, and

o   relative permeability end point during miscible condition

·      History matching is done as follows:

o   Match initial waterflood performance by adjusting

§  Oil and water endpoint relative permeability and,

§  Residual oil saturation.

§  Low critical capillary number.

o   Match of surfactant and chase water performance by adjusting

§  Residual oil saturation

§  Oil-water relative permeability end points

§  High critical capillary number

·      Parameters that affect surfactant flood performance:

o   Surfactant adsorption

o   Permeability

o   Residual oil saturation

o   Critical capillary number

·      Reduction of contact angle by surfactant can be represented by reducing water relative permeability curve slope in the high capillary number relative permeability sets

I did find online trainings about CMG STARS but unfortunately, the trainings will begin in July.

3.  What will I do next? 

I will keep reading bout surfactant simulation using CMG STARS software and Also, I will keep searching for training materials for the software itself.
