Daily Update - Mohammad Elkady - (June-21-2022)

1.  What did I do today?

Today, I attended several technical sessions and did networking with the industry representatives, also I read SPE 195239.

2.  What did I find interesting/Work on?

-       The Delaware basin has several contributing formations.

-       The middle wolf camp acts as excellent seal between upper wolf camp and lower wolf camp. Most oil production comes from the upper wolf camp, lower wolf camp is mostly gassy shale.

-       SPE 195239

o   It is known that data for fluid composition is supplied in its different phases, oil, and gas, and are not usually provided as a combined fluid. This is due to most samples being collected at the surface in non-downhole conditions.

o   The common practice in compositional simulation to mitigate this issue is to recombine the compositions into a single composition at separator conditions. To do this, separator pressure, temperature, and GOR were needed.

o   Separator conditions used are 204 psi, 102 F, GOR of 2000 scf/SEP-stb, and specific gravities (SG) of oil and gas at 0.7812 and 0.774.

o   4 horizontal wells with 160 acre spacing. Each well is located in the SBSG sand and is represented by accurate industry directional surveys. Well lateral length ranges from 4462-4591 ft.

o   A multi-step matching process was used to determine multiple parameters for an accurate representative model. The process was run in CMG CMOST, with 15 discrete levels and a multitude of limits based on known uncertainty ranges.

3.  What will I do next? 

Next step is to gather as much data from a specific area of interest in the Delaware Basin to build a realistic model representative of the area.
