GATE GATE Prho™ has been successfully implemented worldwide for both onshore and offshore facilities. Its multipurpose nature has led to a wide range of applications from production optimization to integrity assessments.
rigorous Surface-controlled Subsurface Safety Valve (SCSSV) test analysis
GATE GATE Prho™ has been used on Gulf of Mexico assets to promote safer well operations through one of its features: rigorous Surface-controlled Subsurface Safety Valve (SCSSV) test analysis. It improves the commonly used SCSSV test protocol in the industry by accounting for the effects of liquid-gas interface existence in the wellbore, wellbore cooldown and suspected leakage through Underwater Safety Valve (USV) during the SCSSV test. It helps the operator to accurately detect SCSSV malfunction.
Determining Production Efficiency & Avoiding Flowline Blockages
Another application of GATE Prho™ is determining the potential production efficiency increase of a parallel dual flowline system in Ghana deepwater, West Africa. It determines the system’s effectiveness and detects the potential flow assurance issues such as flow instability and paraffin deposition. This helps the operator determine the optimal way to operate the asset and avoid the flowline blockage risk.
Corrosion Modeling & Asset Integrity Management
The integration of GATE Prho™ with corrosion modeling has been utilized in both conventional and unconventional wells to assess the asset integrity. In Haynesville, Texas, it has been utilized to investigate the production tubing failures. The study outcomes are used to prevent future tubing failure could have led to significant revenue losses and safety concerns. In a Gulf of Mexico asset, it has been used to identify the potential areas of severe corrosion in the flowlines for targeted inspection.
Time-lapse Nodal Analysis (TLNA)
The seamless coupling of GATE Prho™ and transient reservoir modeling has been applied in a Niobrara shale well to develop the Time-lapse Nodal Analysis (TLNA) in unconventional plays to optimize the production. It predicts the well performance, analyzes the proppant effectiveness and evaluates the artificial lift method. With high number of wells in most unconventional plays, it promotes faster field-scale optimization and reduced cost by increasing the leverage achievable with limited data and modeling time.
