Targeted Micro-encapsulated Solid Vortex Chemical System to Manage Foreign Material

Chemical programs are frequently used to manage foreign materials (both suspended and in solution) in Permian wells. These programs typically rely on surface equipment for mixing and downhole injection to deliver the chemical. This presentation examines the nature of scale, corrosion, paraffin, asphaltene precipitation and H2S in the Permian and presents the case for a targeted micro-encapsulated solid vortex chemical program to supplement conventional surface-based treatment.

The presentation begins with an overview of the mechanisms behind foreign-material challenges and how chemical programs inhibit or reduce these issues. Building on the limiting downhole conditions, the presentation explains targeted microencapsulated chemical inhibition delivered downhole through a vortex tool designed to release the chemical at a controlled, sustained rate. This targeted downhole approach delivers inhibitor precisely where scale, corrosion, paraffin, asphaltene precipitation and H2S originate, supporting more consistent protection and increased flow assurance with less operator intervention.

Candidate wells were screened against a defined set of downhole conditions to identify those suitable for targeted chemical inhibition. Early trials of targeted microencapsulated solid vortex chemical inhibition show reductions in harmful downhole scaling and corrosion environments, improving flow assurance, correlating with improved rod-pump runlife and fewer integrity-related failures. This presentation will share initial field deployment results across multiple wells that demonstrate measurable produced fluid chemistry changes and operational benefits in certain applications. Operational benefits include reduced downtime, fewer workovers, and notable cost savings.
