“…The results are not unique in terms of openhole ESS outperforming other completion systems. These types of results have also been documented in a number of other papers (Wang et al 2003;Nwabueze and Opusunju 2004;Pellicanò et al 2005). Typical increases in well performance are a two-to three-fold increase in productivities (oil).…”

Four expandable completion liners (ECLs) have been run in Algeria in two fields-these are the first fully compliant ECLs in Algeria, the first worldwide in gas wells, and the first worldwide in multilateral wells (from Weatherford database). This paper presents the first detailed benchmark study of ECL performance.All systems to date have been run in 8½-in. hole using 5½-in. base-pipe ECL compliantly expanded, and the installations went well. It has been possible to compare ECL performance data against a comprehensive surveillance data set for the two fields where data from existing openhole completions allow meaningful comparisons. The other completions consist largely of slotted liners and some barefoot completions. The tested production rates in each of the wells have been high relative to normal field trends; however, the predominant factor in this is the reservoir character. Pressure-buildup (PBU) analysis indicates that the second well has reduced Darcy skin, while it is considered unproved in the first well (more data over time are needed). There is, however, consistent evidence for a reduction in the rate-dependent proportion of total skin in both wells. This is supported by other studies and a consideration of basic principles.The reduction in the rate-dependent proportion of skin has given an increase in production rate of 5-20% as compared with the computed rate from a slotted liner. This difference assumes no borehole collapse, with analyses and discussion presented of the effect on well performance should borehole collapse occur.The joint venture (JV) is investigating the further use of this technology in smaller hole sizes and possibly in conjunction with fracture stimulation. Reservoir DescriptionsThe In Salah gas reservoirs are sandstones of Devonian and Carboniferous age. They are hard consolidated sandstones with generally low-to-moderate permeability. The fields typically have multiple sands units that are laterally extensive. The gas is dry, comprising 90-98% methane. CO 2 content varies from 1% in the Carboniferous to 10% in the Devonian reservoirs.Teg is a large four-way dip closed structure with few faults. The infill wells are in the Devonian D55 (Emsian-tidal/shallow marine sand), lower D40 (Siegenian-predominantly clean fluvial sand), and upper D30 (Gedinnian-tidal/estuarine sand/shale) sandstones. The Devonian reservoirs are fluvial to shallow-marine sandstones. Reservoir quality is usually good, with porosities up to 27% and permeabilities up to 150 md, and the sands are laterally well connected. Gas in the Devonian at Teg contains typically 90% methane with 9% CO 2 and 11 ppm H 2 S. The dewpoint at 29 bar is -46°C, water/gas ratio (WGR) is 2 bbl/MMscf, and condensate/gas ratio (CGR) is 0 bbl/MMscf. The Reg field consists of a large four-way dip closed structure covering an area of up to 350 km², which is elongated in a northwest/southeast orientation. A 3D-seismic survey acquired by the JV during the appraisal phase over the crest of the field has confirmed that the structure is exten...

“…Sand production is a common issue in oil extraction, and its existence can reduce well output, shorten the lifespan of equipment, and impact wellbore stability (Wang J L et al, 2003;Wong G K et al, 2003). The causes of sand production are diverse, and through thorough analysis of these causes, we can more accurately identify the key factors that lead to sand production (Al Shizawi et al, 2018;Fattahpour V et al, 2020;Devalve C et al, 2021;Chandrakant A A et al, 2023).…”

Sand production in oil wells seriously affects the production of oil and gas in oilfields. Although conventional sand-control techniques can effectively prevent sand production, it may also limit the productivity of oil wells. Fracturing and packing sand control technology changes the distribution of pressure and flow in the wellbore, while foam polymer resin diversion technology reduces the anisotropy of reservoir permeability and increases the area of oil leakage in the reservoir, both achieving the goal of sand control and increased production. The sand-free production rate is successfully increased thanks to zeta potential sand control technology, which modifies the formation’s sand potential and causes the sand to agglomerate without harming the reservoir. This article first looks into the causes of sand production in oil and gas wells before examining the fundamentals, implementation strategies, and effects of traditional sand control techniques, fracturing and filling sand control technology, foam polymer resin diversion technology, and Zeta potential sand control technology. In this article, the experience of sand control technology in actual oil field applications is summarized, explained in detail, and the future development possibilities of sand control technology are discussed.

“…Development of hydraulic screen technology aims to provide a mechanically strong solution which eliminates aspects of installation complexity associated with specialist tooling or pumping operations, while achieving the well documented enhanced productivity performance of a screen filter placed directly against the sand face (Mason et al, 2007;Wang et al, 2003).…”

Achieving flow performance in openhole sand control completions often requires removal of the annular gap between the screen section and wellbore. For the first time in the industry, patented hydraulic screen technology has been used to provide wellbore support and overcome the challenges associated with gravel packing in depleted reservoirs with low operational margins. This paper demonstrates how new technology has been adopted by an operator in Norway to provide effective downhole sand control in an offshore environment faced with continuous reservoir pressure depletion. Detailed job planning and evaluation of risks when adopting new technology is described.The case study describes a producer well drilled to 2580 m, at a maximum deviation of 30º, and temperature approximately 90ºC. With the sand control equipment run to depth closed ended, the liner hanger and hydraulic screens are set by surface applied pressure. When set, the screens extend radially to close the annular gap and provide wellbore support; production ports in each screen provide the flow path from the reservoir to production tubing. The liner hanger packer was set and reservoir isolation barrier valve closed in the same trip providing testable barriers, prior to displacing the well for upper completion operations.The paper outlines how adopting new technology challenges openhole gravel packing and delivers effective downhole sand control in a depleted reservoir. The operator has demonstrated savings associated to operational planning, logistics, HSE risks and rig time. Production rates meet expectations with all screens contributing to flow.
