Daily Update - Mohammad Elkady - (July-12-2022)

1.  What did I do today?

Today, I have done some literature about excess water production in the Permian basin, I met with Dr. Misra, and I have done some CMG Simulation practice.

2.  What did I find interesting/Work on?

-       SPE-204166-MS

o   The following elements were to be the main focus to provide the frac operation with acceptable water chemistry:

§  Biocide – utilize an oxidizing biocide for complete microbial kill.

§  Additional Oxidizer – reacts with positively charged elements (calcium, iron, etc.) and indirect biocide treatment.

§  Aeration – provides additional oxygen into the pit for oxidizing benefits as well as mixing the pit contents to prevent stratification.

o   Untreated produced water indicated the presence of acid producing bacteria (APB) and sulfate reducing bacteria (SRB). These bacteria can thrive in anaerobic reservoir conditions and become very detrimental to production via plugging or corrosion

o   Pit design and cost estimates focused on the ability to accommodate produced water. The initial pit construction cost was estimated to be $679,040 or $1.36/bbl

o   The pit liner system incorporates a 40/200/40 mil liner design. Multiple liners are required to protect freshwater and allow for a leak detection system to be installed

o   This arrangement is the major capital expenditure and a reason why produced water pits tend to leave an operator with a sense of sticker shock when considering produced water management.

-       I met with Dr. Misra and he gave some guidelines and points on the direction we should focus on.

3.  What will I do next? 

Next, I will focus more on simulating more reliable simulation and I will prepare PowerPoint slides regarding that.
