Application of Shear Gas Lift Valves in the Pre-Salt Buzios Field Since the beginning of pre-salt oil production, Petrobras has identified over 25 cases of failure in gas lift valves, characterized by unwanted flow from tubing to annulus. Out of these, at least 14 cases have required a rig intervention to replace the damaged valve. […]
A Review of Intermittent Gas Lift and Fallback Factor Modeling Objective/Scope At some point in the producing life of a gas lifted well, it is recommended to switch from continuous gas lift to some type of intermittent gas lift. Various methods such intermittent gas lift with a downhole pilot valve, gas-assisted plunger lift with a […]
Avoiding environmental and financial impact of stuffing box leakage! Avoiding environmental and financial impact of stuffing box leakage! Rob Harrison, M.A., SCMP / Well Site Guard Ltd. 2023 International Sucker Rod Pumping Workshop Aug 28-31, 2023. Midland TX Why do we need containment on our production wells?
Cloud Based Real-Time Monitoring of Tight Oil Field by Applications of Edge Gateway Device, Automatic Fluid Level technology and Analytical Dashboards Presentation Data-monitoring & field-optimization in tight oil fields is a challenging task without innovative technologies and digital-analytical platforms. In SRP wells, real-time dyna-card and continuous fluid-level data are valuable to understand downhole pump-performance and […]
Technical, Operational Challenges & Solutions Innovations in Developing Unconventional Tight Oil High GOR Field, India Presentation
The Ken Well Manager: An Adaptive Controller For Dynamic Deviated Wells Presentation Most current pump-off control devices function using theory and technology developed in the 1970s, when “vertical” wells were more prevalent. For communications, costly mesh radio networks are installed in conjunction with SCADA host programs to allow for data acquisition, requiring expensive infrastructure and […]
Autonomous VSD Setpoint Optimization for Sucker Rod Artificially Lifted Oil and Gas Wells Presentation Utilizing a Variable Frequency Drive (VFD) is a more sophisticated method to allow operators to increase their runtime by detecting when there is less fluid to produce and slowing the unit down, accordingly. Optimizing VFD setpoints is not necessarily challenging, but […]
Increasing Production by Using a Two-Stage Filtration System: Case Studies in South Texas Presentation To deal with gas and sand problems in their conversion and rod pump wells an operator in south Texas started introducing a combined technology of two-stages solid filtration with a modified poor boy gas separator obtaining excellent results. This paper explains […]
Sucker Rod Modeling in 4-D Presentation Sucker rod systems in deviated wells experience friction due to lateral forces exerted on the rods. These lateral forces change throughout the stroke as dynamic loads traverse the rod string. New sucker rod design/analysis software can model the lateral forces in 4-D (3-D reactions in time) to provide superior […]
A discussion of Rod Lift VSD control parameters, setup, and configuration for optimal operation under varying operating conditions Presentation History shows that many operators utilize only the most basic control parameters when setting up VSDs for rod lift applications. This paper will discuss the VSD and Rod Pump Control parameters necessary for safe, reliable, and […]
