Improve and stimulate the existing fracture network with refrac system
Challenges in ReFracturing

ReFracturing in the shale formation is the process of re-injecting pressurized fluids into the wellbore to create new or re-stimulate existing fractures in the shale formation. The purpose of this process is to increase production after it has substantially dropped to marginal levels. Also, This process involves injecting fluids and proppants into the wellbore to create or re-stimulate fractures in the shale formation, which increases the permeability of the formation and allows for increased oil and gas production. Additionally, re-fracturing can unlock previously untapped shale reserves. Hence, reFrac process is an effective solution to improve and stimulate the existing fracture network, reduce initial fracture spacing, which gives access to unperforated pay zones in the shale reservoir.
This process should be dependable and trustworthy, occur quickly, and be cost-efficient without compromising the quality of the outcome. It should also be able to be repeated with the same results, be easy to use, and be budget-friendly.
Solution for ReFracturing
Saltel Expandable Steel Refrac Systems
- Use a straddle tool to frac or refrac between two expandable steel packers
