Navigating today’s energy landscape requires more than experience—it demands deep technical insight and agile problem-solving abilities. Evasil’s Technical Consultancy service supports operators throughout the upstream value chain, from field appraisal to production optimization and late-life asset management. Our multidisciplinary consultancy team brings decades of hands-on and academic expertise in reservoir engineering, production chemistry, flow assurance, […]

Well integrity management is critical for safe, sustainable oil and gas operations. At Evasil, we offer Well Integrity Solutions for aging assets from active lifespan to decommissioning; thus, ensuring assets remain safe, productive and compliant. We utilise risk-based integrity assessments, leveraging both historical data and downhole diagnostics such as cement bond logs, ultrasonic imaging, and […]

As oilfields mature, water production surpasses hydrocarbon production. With the increasing volume of water and potential reduction of the stream residence time, the efficiency of most oilfield produced water treatment vessels declines. At Evasil Engineering Limited, we understand the complexities of produced water and the urgency to manage it responsibly and efficiently. Our Produced Water […]

Flow Assurance: Ensuring Uninterrupted Hydrocarbon Flow with Evasil In the complex world of oil and gas production, ensuring the continuous and efficient flow of hydrocarbons from the reservoir to the point of sale is paramount. This process, known as flow assurance, involves predicting, mitigating, and managing potential issues that could disrupt hydrocarbon flow, such as hydrate […]

Production Chemistry: Enhancing Oilfield Efficiency with Evasil’s Expertise In the oil and gas industry, maintaining optimal production conditions requires a deep understanding of the chemical interactions occurring throughout the production lifecycle. This is where production chemistry becomes indispensable. It is the science and engineering discipline that ensures safe, efficient, and economic production by preventing chemical-related […]

Microbial Induced Corrosion (MIC): A Silent Threat, A Scientific Solution Microbial Induced Corrosion (MIC) is one of the most underestimated challenges in the oil and gas industry. It’s invisible to the naked eye but can lead to catastrophic damage to oilfield infrastructure. MIC is triggered by an array of archaea colonies migrating from the aqueous […]

Inorganic Scale Management: Protecting Performance at the Core Inorganic scale buildup is a persistent problem in oil and gas operations, silently compromising equipment, reducing flow efficiency, and increasing operating costs. These mineral deposits, commonly calcium carbonate, barium sulfate, and strontium sulfate—form when incompatible fluids mix or pressure and temperature conditions shift. Left untreated, they can […]

Water & Gas Shut-Off Solutions:  Influx of water into the wellbore or unplanned gas breakthrough negatively influence hydrocarbon production and field operations. When these phenomena occur, the operator may want to consider reservoir conformance treatment or zonal isolation. Evasil’s Water & Gas Shut-Off Solutions are engineered to help operators regain control of their wells by […]

Reservoir Souring Control: Safeguarding Asset Integrity and Operational Safety Reservoir souring is a silent yet significant threat to oil and gas production. The increase of hydrogen sulfide (H₂S) levels in a reservoir over time, often caused by sulfate-reducing bacteria (SRB)—can severely compromise asset integrity, reduce well productivity, and expose operations to serious safety and environmental […]
