... and assembly. Non-Destructive Examination (NDE) – Magnetic Particle Inspection (MPI) was selected to inspect the fillet weld joint connections because RT or UT is not practical. Considering the possibility of delayed cracking, fillet welds were inspected using MPI after 3 days of weld completion, and MPI...

... retrievable gas-lift systems with metal-to-metal seals capable of sustaining a differential of 17 Ksi and injection rates of 15 MMscf/day. This paper provides an overview of Vito's drilling and completions, in-well gas-lift system, development process, validation and testing requirements, key challenges...

... Net Zero Technology Centre. The demonstration project adopts a phased approach, with the ultimate objective of demonstrating a wave energy converter and seabed energy storage system for subsea power delivery. Phase 1 comprised the completion of a detailed front end engineering design (FEED) study...

... production. The injected gas accumulates to form or enhance a gas cap, while oil and water drain by gravity towards the base of the reservoir due to their heavier densities. To further enhance oil recovery, and to overcome the economic limitations of using vertical gas injectors, multi-completion production...

... Abstract The durability of sand screen completions is essential to longer well life, especially for high rate wells with sand screen erosion concerns. An excessive fluid flow enters the conventional screens near the heel or high permeability/fracture zones, causing premature sand control loss...

... the reservoir fluid influx entering the wellbore and therefore optimise the well performance. To improve oil production and ultimate recovery, AICDs were incorporated in the lower completion design for the development wells. The Rate Controlled Production (RCP) AICD was chosen for this application...

... sections and setting 2 casings, completing it by running in hole lower and upper completion together (TOT - True One Trip). The well design of 7-GLF-49H-ESS is a real example of this concept implementation, originally approved with an estimated average duration of 96.6 days. The original scope included...

Key lessons learned from previous deepwater projects ensured that the team was focused on successful completion of well cleanup and handover from drilling and mitigating any flow...

... The operator set-out to select a tool with higher capabilities, but there were none available in the industry for the last liner size in this well (7 5/8"), therefore a service company was selected that was able to develop such tool in a tight 6-month deadline, to allow this well to be completed...

... South China Sea is one of the offshore HPHT region, with the maximum 2.38 pressure coefficient, 480 degF bottom temperature and 50% CO 2 . The drilling and completion are challenging problems. This paper reviews the past 20 years' researches and practices in South China Sea HPHT area. Based...

... This paper addresses the hurdles that have prevented the single-trip installation of upper and lower completions in the complex world of subsea and deepwater applications. It examines the processes, technologies, and risk mitigation steps that took a concept from pilot to successful deployment...

... waste and maximize efficiency of the campaign; as well as efforts and arenas to systematically promote collaboration, openness and regular experience transfer among the different parties involved (operator and contractors). Since the pre-drilling campaign was completed, the Johan Sverdrup project has...

.... An overarching theme from each team was to apply environmental solutions. Colonization of hard coral species and presence of several fish species were observed on project completion. For example, a 70% increase in growth of Seagrass and artificial coral reefs was observed near the causeway built for the Manifa...
