Title: Physics Based Recovery Factor Model Case Studies: Haynesville Parent-Child Protection Evaluation and Eagle Ford Productivity Degradation from Inter-Cluster Communication.
Abstract:
· Physics based model discussion, OIP and GIP from logs maximum recovery factors for oil, condensate, and gas known
- Data strongly supports reorientation hypothesis (URTeC 3724057)
- Maximum recovery factors are not being achieved (URTeC 4042322)
- Child well EUR degradation numbers (Elliot 2019) validated (SPE 213075), defensive refracs work well at mitigating child well asymmetry
- Offensive and defensive designs have opposite objectives (SPE 213075)
- Strong evidence of inter-cluster communication with < 20 ft spacing or random 20 ft spacing (ignoring depleted cluster locations)
- Inter-cluster communication reduces or eliminates injection into higher stresses, entire stage volumes could be lost into marginally productive rock
- Should see maximum recovery factors for all recompletions independent of cluster efficiency due to reorientation (URTeC 3724057)
- Proposed damage mitigation strategies for offensive recompletions, defensive refracs provided the child well degradation statistics and may be currently optimized if primary goal is to recharge depletion
- Many parent recharges have close well spacings, recoverable OIP/GIP based on well spacing and lateral length acreage x OIP/GIP per acre
- If the drainage area is small or OIP/GIP low the uplift from the recompletion may be minimal
- DeWitt major operator zero uplift from three defensive refracs with 350 ft well spacing in the oil window. Offset child wells should make the type curve, this is worth looking into.
Bio:
Bob Barba has 44 years practical experience as a petrophysicist and completion optimization advisor. His current focus is on derisking recompletion candidate selection studies for operators and non-operated working interest investors. Also operates a 19 well vertical gas field in the Ozona field where a major oil based refrac program is planned once Waha returns to normal pricing. Bob is the most published author in the oil and gas industry on mechanically isolated recompletions. He has 20 publications and industry conference presentations on the subject with six of the publications in major industry magazines in the last four years. He currently teaches the recompletion and new well “best practices”, openhole log analysis, organic shale petrophysical analysis, and cased hole logging courses for Subsurface Consultants and Associates worldwide. He also teaches the online recompletion optimization course on the Saga Wisdom platform.
