Advances in Openhole Packer/Sleeve Completions Coupled With Multilaterals Provide Cost-Effective Solutions

Abstract

The Bakken Shale located in North Dakota has seen large increases in oil and gas production. The contributing technologies that have aided in the increased production are the recent advances in openhole packer and sleeve completions. These completions have enabled operators to isolate and fracture up to 24 stages using a one-trip openhole packer and sleeve completion.The use of multilaterals enables operators to save capital investment by accessing production from two laterals while drilling a single vertical wellbore. Greater drainage access across a section is also achieved by using this technology. Coupling multilateral and openhole packer/sleeve technologies together allows for multiple-stage hydraulic fracturing operations of both laterals. This paper will show how employing openhole packer and sleeve completions coupled with a fracturable multilateral junction provides a cost-effective way to drill, complete, and stimulate wells in the Bakken. The experience gained in the Bakken will be applicable worldwide as operators look to optimize openhole completions in their unconventional reservoirs.

Advancements and Operational Insights in the Bakken Shale: An Integrated Analysis of Drilling, Completion, and Artificial Lift Practices

“…The study emphasized the effectiveness of longer laterals, staged treatments, and cleaner fluids, along with the importance of fracture design and proppant selection. Johnson and Courrege [18] reported on the increased oil and gas production in the Bakken Shale using openhole packer and sleeve completions. This technology proved beneficial in maximizing exposure to hydrocarbon reserves and reducing environmental impacts.…”

“…The geometry and material selection for the ball and ball seat is what ultimately determines the pressure rating of the system. A differential pressure is created across the ball during fracturing operations (Johnson 2010 The operational steps for the completion method that employs multistage frac system (open hole packer system) is outlined below:…”
