Compared to traditional fracturing and acidizing techniques, the Temporary Plugging Diversion Stimulation Technology (TPDST) enables refracturing and acidizing in aging wells, achieving flow diversion and increasing the Stimulated Reservoir Volume (SRV) in coalbed methane (CBM) and shale reservoirs. The Composite Temporary Plugging Technology offers comprehensive refracturing solutions and services for all well conditions.

To achieve uniform and refined stimulation, conventional carbonate reservoirs can also design tailored temporary plugging schemes based on different completion methods. For instance, in casing completion, using temporary plugging knots can effectively and precisely seal the perforations in long perforation sections, achieve interlayer and intralayer temporary plugging and diversion, and partially substitute mechanical layering. In open-hole completion, a composite temporary plugging scheme can be used to achieve temporary plugging within the fracture, thereby attaining refined and uniform stimulation.

The novel anti-sedimentation fibres developed by our company utilize graphene nanomaterial technology to enhance the interaction of interfacial charges, enabling fibres and proppants to form a uniform and stable three-dimensional network structure in slickwater; overcome the gravity settling of proppants, improve the long-term structural stability performance of fibres and proppants, and form a stable structure that maintains a high height in the fracture for a long time.
