The formation and deposition of solids including mineral scale, paraffin, and asphaltene, may occur at any location of the oil and gas production system, from the bottom of the well to a gathering facility, due to the changes in the physical and chemical conditions associated with production fluids. Depositions can reduce the formation permeability, reservoir transmissibility and have detrimental impact on production rates during oil and gas production. Common practice is to complete the well and then apply a treatment and remediation program as necessary, including squeeze treatments and batch treatments.1
Horizontal, multi-stage hydraulic fracturing is widely used in the industry as stimulation practice.2 A single application providing long-term treatment is financially and operationally beneficial for operators. A solid inhibitor with slow-release active additives can extend the treatment life and reduce subsequent intervention costs attributed to deposition prevention and/or removal.
This paper reports on a new, slow-release particle technology developed for applications in hydraulic fracturing. This new technology does not rely on adsorption, impregnation or any other technology of embedment of additives onto a substrate. The new slow-release particles exhibit improved delayed release profile, high strength, and the capacity to incorporate active components, such as scale or paraffin inhibitor, either singly or in combination.
