Restimulate and reconnect with the reservoir

Refracturing describes the process of hydraulically fracturing a well after the initial fracturing operation and production period.The BroadBand Sequence fracturing service is used to pump refracturing stages in succession while launching a proprietary composite pill in between each stage to divert out of the previously stimulated zone ensuring new reservoir rock is stimulated along the entire wellbore in both horizontal and vertical wells. Effectively refracturing each wellbore enables wells to increase production flow rates.

Refracture in challenging conditions

Effective refracturing operations can significantly improve production from previously depleted laterals. However, the combination of existing perforations and a depleted reservoir greatly alters the in situ stress, which makes it challenging to develop a plan that accounts for the well’s unique conditions. Using integrated software and services, we can design a successful refracturing strategy for a candidate well.

Is your well a good candidate for refracturing?

Protect the parent well with refracturing

A critical consideration for reservoir management is protecting the parent well through refracturing before completing offset infill wells. If the parent well is not refractured, then hydraulic fracturing of the infill well will likely negatively affect the parent well’s production, causing it to lose significant future production potential. The infill well is similarly adversely affected, losing energy to the existing fracture network to reduce its recovery potential. Parent well protection reduces the impact on rock stress caused by depletion—maximizing reservoir contact for greater production and higher recovery.
