... intervention platform to meet the requirements. The upgrade of an existing 20,000-psi slim electrical-line instrumented and automated intervention platform was selected as an economical and technically feasible option to meet the operator's requirements. The 20,000-psi slim intervention platform met three...

... Abstract High sour fields beyond 10% H 2 S concentration are considered one of the severe environments that require suitable tubular components and accessories in upstream environment to ensure sustainable production. Such environments represent a challenging operating envelop where durability...

... scoping the well control and ancillary equipment to enable successful pumping and wireline operations on a sub-ambient well under elevated subsea and surface metocean conditions. Additionally, surveillance was necessary to assess damage and allocate contributions from each zone. Individual isolation...

... Abstract This paper will be focused on the engineering process for first-time experience workover operation in shallow water depth with a 6th generation semisubmersible drilling rig. The 6th generation semisubmersible drilling rig is designed for operations in water depths of up to 3000 meters...

... compaction and fines migration, causing solids to deposit and build up in completion screens. It also increases temperature profile from the well, assisting in flow assurance issues and minimizing possibility of dynamic hydrate formation. The gas injection operation is performed periodically, shutting...

.... This was mainly because of high friction pressures that would result from the pump rates needed for efficient milling operations and hole cleaning. Therefore, a custom-made larger OD string had to be designed and procured for the project. The CT string design and selection for this unique project were based...

... Abstract In a continuous effort to reduce cost and improve efficiency, the Oil and Gas industry has been trying for the last 10 years to develop methods to perform subsea Coiled Tubing (CT) operations from a vessel and without a riser. In September 2020 a large campaign of Riserless Coiled...

... Two solutions are clear in this situation: the operators may choose to wait on the service companies to take the initiative of offering well access systems in Brazil, which would increase competitiveness in this market and potentially meet a suppressed demand that could be unleashed, or they may...

... with a structured process to maintain data quality. Recent interventions have both contributed to capturing new learnings and implementing those already identified into the planning phase of upcoming operations. Time and cost estimation accuracy and operational efficiency initiatives were then evaluated...

..., of completion and intervention tubulars utilizing this system have been deployed with zero pipe body downgrades due to corrosion or pitting, and zero operational issues. In addition to reducing replacement cost and loss of capital, this system provides the ability for longer deployment of the pipe on a multiple...

... differential sticking hazards, while also offering additional benefits in operational efficiency and data quality. A case study from a particularly difficult well in New Zealand is presented. Data acquisition in this well was fraught with challenges: In addition to the 2000m tangent section at 67° deviation...
