... Abstract Openhole gravel packing has proven to be one of the best sand control completion methods in the industry with high reliability and low skin. As more and more wells are being drilled in challenging environment (long drain lengths, depleted formation, wellbore stability concerns...

... Abstract High Rate Water Pack (HRWP) treatments are used in cased hole gravel packs with the intention of creating small fractures to bypass near wellbore damage and improve perforation packing. Despite their popularity as a sand control technique, there has never been a software model...

... Abstract Downhole gauge (DHG) data analysis is a powerful tool in not only identifying, or minimizing the potential number of, root causes for any failures that may occur during gravel packing, but also in either verifying or calibrating friction pressure data used in gravel placement...

... Abstract Viscoelastic Surfactant (VES) fluids have been used in many openhole gravel packing applications with the shunt tube technique as they offer several advantages over polymeric fluids. However, existing VES fluids have temperature limitations. The objective of this work was to develop...

... Abstract This paper presents the design and execution of an openhole gravel-pack completion campaign in deepwater West Africa. Based on field history and past challenges, a novel approach was implemented to address the low fracture gradient. Various aspects of the gravel pack design...

... Abstract Most of the deep water reservoirs in Angola are weakly consolidated sands, requiring sand control, and openhole gravel packing is one of the most widely used sand control techniques in the area, Block 15/06 being no exception. High inclination wells targeting multiple reservoir...

..., and reducing risk, the result indicates that the Cased Hole Gravel Pack with Alternate Path System was preferential. Additional information was obtained in the latest campaign during the retrieval of gravel pack screens in 2 sand producing wells, which gave a better understanding of the failure mechanism...

... conditions caused several well problems, even sand control failure. The analysis of producer wells with sand control has shown an interesting behavior, confronting the concepts adopted by Petrobras. As expected, for producer wells, the failure rate is low for open hole gravel pack and fracpack, higher...

... Abstract For HPHT wells it appears that the only industry practice for open hole sand control has been Stand Alone Screens (SAS), even for wells that should have been gravel packed. For North Sea HPHT field developments, SAS has been chosen as the open hole sand control method. However...

A model to describe contact between granular materials (gravel and formation) and soil-pipe interaction is proposed. Results demonstrate that perforated base pipes used in premium...

... extension of the reservoir, the decision was made to develop the field with horizontal openhole gravel packs for both producers and injectors. Fifteen production wells and eleven injector wells were drilled and completed in the field. As a result of the perceived technical complexity of the development...

... Abstract When a Gravel Pack Completion fails it usually results in the loss of production from the interval until a workover rig is available to re-complete the well. This paper describes two recent successful rigless interventions completed in offshore multi zone completed gas wells...

... Abstract A major issue for deepwater high rate wells is delivering completion reliability and performance that ensures well life sand control and operational simplicity. Multi-path screen systems are designed to ensure placement of the annular gravel pack in frac pack applications...

... and perforated, open hole gravel packs (OHGP) using wire-wrapped, pre-packed and alternate path (shunt-tube) screen technology, stand-alone porous metal fiber premium screens, and expandable screens. To date, 29 completions have been installed in 19 of 24 available well slots in primary and sidetrack wells...

... Abstract A large majority of the recent deepwater developments in West Africa require sand control applications. Openhole gravel packing is the preferred sand control technique adopted by many operators in this region. It is considered one of the proven methods of sand control from both...
