Oil & Gas
Engenya supports service companies as well as operators in their efforts to maximize productivity while minimizing risk and cost. Over the years we have designed and audited downhole tools, developed completion simulations and led failure analyses for clients worldwide…
Concept design, sensitivity analysis, trade-off analysis, system analysis, risk analysis, risk management, performance analysis, performance optimization, design optimization, detailed design, predictive analysis, testing, validation, failure analysis.
Electric Submersible Pumps have to work reliably for years to ensure production in wells that require artificial lift. Their failure is extremely costly and while impossible to completely avoid, managing the risk is possible. Engenya can help you by running a virtual installation to understand the loads the system will experience.
Linear and non-linear analysis, static and dynamic analysis, transient analysis, coupled phenomena, aerodynamics, vibration, time domain, frequency domain, frequency response, thermal analysis, thermal management, fluid mechanics, fatigue, damage tolerance.
Event reconstruction, root cause analysis, hypothesis development and testing, system analysis, inspection, metallurgical testing, scale testing, validation of physical principles, detailed reporting.
Verification of requirements, verification of design specifications, performance analysis, integrity, risk identification and assessment, failure modes and effects analysis (FMEA), compliance analysis, compliance reports.
