An unsupervised learning method for choke erosion prediction was validated through hindcasting that could have avoided expensive choke washouts by early intervention...

... of well accessibility for rig-based well interventions, these complex completion configurations add significant challenges. Upon drilling is completed, coiled tubing (CT) matrix acid stimulation is one of the first interventions used to remediate the formation damage and bring the well back on production...

Most variants were deployed via slickline intervention with the option to retrieve later in the well life. The intelligent safety valve is a fully autonomous system, API14A qualified, device that enables the safe...

... debottlenecking, advanced data acquisition campaign including multi-phase flow metering, and other low-cost, well intervention retrofit applications. All these efforts have resulted in sustained natural gas production of over 300 MMscf/d with associated 5,000 bpd of condensate in the past decade. This paper...

... Preparing the industry toward the future may prove to be the most important outcome of the application as Automation in Directional Drilling is the ability to operate a system with minimum human intervention while automating most analytical repetitive tasks. The principal approach...

... of Zone 1 and Zone 2 at the time the well commences production. Shifting the sleeves requires a wireline intervention. This requires mobilizing a semi-submersible rig to deploy a riser from the subsea tree to the surface where wireline equipment is attached to deploy a shifting tool. A smart well...

..., for evaluation of the well intervention (zone isolation) efficiency as well as for gas tracer breakthrough timing confirmation. This novel approach provides the ability to accurately allocate production at reservoir and surface level virtually at real-time based on daily production data from test separator...

Gas lift compression is set up for single well or multiple well injection utilizing one compressor. Smaller gas lift compressor packages (less than 250 hp) are typically not engineered specifically...

... of flowlines. Thermal intervention methods for removing wax deposition include: Hot Oiling and Electrical Heater. Hot oiling is one of the most popular methods of deposited wax removal. Wax is melted and dissolved by hot oil. This allows for the continuation of production for a period of time until the wax...

... that the optimum gas injection rate can be selected to achieve the maximum production throughout the life of the well over time as Bottom Hole Pressure declines, without the need for wireline intervention to change out a valve, which is required with conventional gas lift. Tailored well designs applications were...

... presents challenges to cost-effective reservoir management. Vertical observation wells are usually drilled in different locations to monitor the reservoir and assist with planning and intervention decisions by running periodic logs to obtain subsurface information. However, these wells can be costly...

...-directionally, permitting accurate, incremental positioning of the downhole hydraulic valves. The EHSA hydraulic pump is free to rotate, no check, relief, and solenoid valving is in the flow path, permitting mechanical remedial intervention throughout the well. To OPEN a hydraulically operated downhole...

...). A common challenge in PL wells is the occurrence of liquid loading events, during which the mass of the liquid column and plunger becomes too large to be naturally lifted, and manual intervention techniques are required to bring the plunger and liquid back to the surface. One such intervention technique...

.... Conceived to validate flow in unstimulated wells / stages, the longevity and value of the data collected led to extending this application for long term flow assurance monitoring of unstimulated and stimulated wells. Spinner based production logging techniques require intervention and have limited...

... with planning and intervention decisions. However, these wells can be costly and occupy valuable space that could be utilized for production. An alternate technique enables E&P companies to drill a pilot hole, perform all the necessary logging, and obtain the required reservoir information. The pilot hole...

... Abstract Subsea completions offer a number of advantages, but intervention operations can be complex and expensive. A horizontally completed multilateral well exhibited unexpected sand production and a tubing leak leading to the well being shut in. This paper discusses the novel tools...
