A large number of contracts were executed to deliver the FPU including separate topsides engineering, hull engineering, topsides fabrication and integration, hull fabrication, and systems completion contracts. The Anchor hull was fabricated in South Korea...

.... Discussion Considering the results obtained, the importance of using these resources in reservoir management strategies in P-77 and in Búzios is observed. The flexibilities of WAG cycling, and wells equipped with intelligent completion, combined with other resources, such as tracer injection...

... The Bonga TAM team tasked itself to delivering a best-in-class TAM and therefore sought value improvement opportunities. One of which was a World Class Start Up and Ramp Up (WC SURU) delivery post activity completion to mitigate against the oft repeating value erosion associated with poor...

...Well Candidate Screening Identifying candidates for injection and monitoring wells Assessing the integrity status of other wells in the field Conducting a deep-dive well integrity assessment on candidates for re-completion, including casing stress analysis, conductor pipe stress...

... recommendation was the first step after completing the tree algorithms. In addition to the knowledge of the designers expressed in the algorithms, it was possible to take advantage of the accumulated historical knowledge of Petrobras. To use this dataset in a structured manner, an Extract, Transform, Load (ETL...

... equipment heavy lifts. Utilization of this proven solution enabled installation campaigns to be completed in weather conditions and contingency scenarios that could not have been completed with alternative installation methods. Abstract The Anchor floating production unit (FPU) is a Chevron Gulf...

... technologies helped to increase safety, cut costs, and raise oil production. Shale drilling in high angle sections and sand production control have been done on a routine basis in the wells completed in deepwater Campos Basin. As result of that, during those years, several world records were set for subsea...

... All-electric completions go beyond just replacing multiple hydraulic control lines with a single electric cable: They open the possibility of controlling conventional equipment such as gas lift valves or chemical injection valves with much higher precision with control from topside of any...

... For a successful execution, proven oilfield drilling technology and services are utilized with a well completion that includes a patent pending vacuumized dual tubing completion to minimize the heat loss of the returning circulation fluid in the well. The drilled depth determines the temperature...

... 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...

... 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...

.... This drillship has been customized to accommodate surface well testing equipment spread and all the tools required for drill stem testing (DST) operations. ▪ Achieve all objectives within current health, safety, environmental (HSE), and regulatory standards. ▪ Complete the well test program within...

... 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...

... 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...

... was further complicated by the COVID-19 pandemic and safety protocols put in place to keep the workforce safe. Three aspects of achieving First Oil are discussed, highlighting challenges and lessons learned: Managing subsea completions, well cleanup, and flow assurance while drilling was ongoing...

... Abstract Open hole (OH) completions are not very common in the GoM, but the area has seen an uptick in OH wells in recent years, and a few big projects have elected to use the same completion archetype. There are several different ways to complete an OH well, and one of these completion...
