Daily Update - Mohammad Elkady - (July-07-2022)

1.   What did I do today?

Today, I started the new model with the low water cut and I did more literature about the geological parameters and excess water in the Delaware Basin.

2.   What did I find interesting/Work on? 

Permian Produced Water: Impact of Rising Handling Costs and Larger Water Cuts on Wolfcamp Growth:

-          In some cases, water-to-oil ratios (WOR) in the Delaware Basin can reach as high as 15:1 and operators are unable to cheaply reinject all those volumes.

-          The challenge now is that unconventional operations pose a series of different considerations from conventional fields.

o    Produced water cannot be reinjected into tight formations for water floods or EOR, in the same way, they could in conventional fields. As a result, produced water must be disposed into saltwater disposal (SWD) wells or recycled and reused.

o    Water demand is also increasing as operators strive to improve completion efficacy. Volumes pumped per completion are over 80% higher than in 2015, close to 15 million gallons of water per current well in the Delaware Wolfcamp. This also results in growing volumes flowing back to the surface, because the formation has relatively high water saturation and does not hold fracture fluids.

o    Multi-well pad development also results in a higher concentration of produced water in a single geography. This can put greater strain on nearby SWD wells and cause sections of disposal formations to pressure up too fast, limiting the injection rate and creating casing issues in proximal areas of the play.

-          This paper focuses on the problem itself and how serious it is.

Today, we created the model with the lower water cut with suitable geological parameters and we got a perfect match with the oil production, but we should work more on the water production match.

 

3.   What will I do next? 

Next, I will tune some of the parameters to get better match with the water production, also I will do the modifications we discussed in our meeting
