Solid Inhibitor Technology: Advancing Well Protection in the Middle East Oilfields

(MENAFNEditorial) The oil and gas sector in the Middle East continues to face persistent well complications that compromise production efficiency and equipment reliability. Scale deposition, paraffin buildup, corrosion, and emulsions remain among the most common challenges for onshore oilfields, directly reducing the lifetime of electrical submersible pumps (ESPs) and tubing. Each year, operators allocate significant budgets to workovers, chemical treatments, and ESP replacements. In this environment, reliable scale inhibition and paraffin control technologies are a priority.

L-Reagent LLC has introduced TRIL®, an innovation in solid inhibitor technology, specifically designed to protect downhole equipment from oilfield complications. Unlike liquid injection systems, which require surface pumps, tanks, and constant monitoring, TRIL® solid inhibitor containers are installed beneath the ESP and deliver autonomous self-dosing. As produced fluids pass through, the active inhibitor dissolves gradually, forming a protective film that prevents scale formation, reduces paraffin deposition, and mitigates corrosion risks. This approach eliminates infrastructure costs and ensures consistent long-term protection.

The technology has already demonstrated its efficiency in extensive field trials across 83–95 wells with varying characteristics. Results showed that only 9% of wells equipped with TRIL® required scale cleanout (SCO) after hydraulic fracturing, compared to 33% when using other reagents. In terms of cost efficiency, TRIL® protection amounted to just 28% of the baseline SCO cost, while liquid reagents reached 85%. The average number of SCO operations per well decreased from 3.14 before TRIL® installation to 0.36 after. Furthermore, in 93% of ESP dismantling cases, no scale deposits were found. Building on this global evidence, the first project in the Middle East has now been initiated in Oman, giving operators the opportunity to test TRIL® solid inhibitor containers under regional conditions.

For regional operators, especially in onshore oilfields, the adoption of TRIL® represents a strategic solution to reduce operating expenditures and improve asset longevity. Scale inhibitors, paraffin deposition control, corrosion protection, and ESP reliability are no longer separate challenges but can be addressed through a single integrated system. By minimizing the frequency of hot oiling, scraping, and chemical injection interventions, TRIL® contributes to lower downtime, greater production stability, and sustainable cost reduction.

The expansion of TRIL® into the Middle East underlines the company’s commitment to delivering oilfield chemicals that meet the highest performance standards. With proven global practice and technical support available through regional offices, the technology positions itself as one of the most advanced systems for scale inhibition and ESP protection currently available. For oil companies facing the dual challenge of maintaining production and cutting costs, TRIL® offers an evidence-based path forward — merging innovation, efficiency, and long-term reliability.
