Who We AreSPE is the largest individual member organization serving managers, engineers, scientists and other professionals worldwide in the upstream segment of the oil and gas industry.

SPE/ICoTA Workshop: Refracturing Through Optimized Interventions

Across all oil and gas plays, the rapidly evolving approaches to completion and stimulation design and deployment has created enormous opportunities to re-enter and re-stimulate wells that were treated early in play development. Refracturing creates a highly attractive opportunity for many of these wells. Subject matter experts will present case study presentations on extensive field experiences and provide technical updates on refracturing. This workshop is an opportunity to network as well as to learn the newest developments.
