“…In gas-coning situations an equalizer can significantly reduce GOR values. Salamy et al (2006) have reported a 50% reduction in GOR when an equalizer was deployed for a horizontal well in Shaybah Field. This field observation echoes the gas coning results in this paper.…”

Equalizer production systems and inflow control devices are used to mitigate water or gas-coning problems for mature fields. We have developed new modeling methods to simulate equalizer and interval control valve (ICV) performance in fullfield multimillion-cell reservoir models under a parallel computational environment.The authors present single-well performance predictions with and without an equalizer, and the results are significantly different in some cases. Full-field modeling with equalizers and ICV controls for several examples has been conducted. In such cases, many individual wells would have significantly improved performance. At full-field level, however, using equalizers or smart well applications without total field optimization would not improve performance much, for reasons discussed in this paper.The frictional pressure loss across an equalizer can be considered as a skin, and we have developed an analytical well equation to include it. With this theoretical development, it is now possible to confirm or monitor equalizer performance in terms of pressure drop from pressure transient analysis.q o ¼ PI o ðP r À P w À r o ghÞ;(2).

“…These wells were extended to 2-to 3-km single-lateral horizontal wells by 2000, then to MRC multilateral (ML) wells by 2002, and to MRC ML wells equipped with hydraulic flow-control valves by 2004 (Salamy et al 2006). The drivers for increased reservoir contact and downhole control included lower unit-development costs, higher well productivity, higher cumulative-oil production before gas breakthrough, and control of production after breakthrough (Saleri 2002;Salamy et al 2006Salamy et al , 2008. Saudi Aramco has more recently embarked on extreme-reservoir-contact (ERC) wells with reservoir contact frequently exceeding 10 km by increasing both the number of laterals and their lengths.…”

“…Early studies involving production logs for more than 60 single horizontal wells of 1-km length showed average flow contribution from 85% of the horizontal section with a generally uniform flow profile (Saleri et al 2003). A significant contribution from laterals greater than 1 km in length is implied from performance data (Saleri et al 2003, Salamy et al 2008), but profile data for laterals drilled beyond this length, and in ML wells are sparse, with FCV installation precluding production logging in most instances. In addition, through the process of actuating valves in wells equipped with FCVs, dead laterals were discovered and were subsequently cleaned up (Al-Dossary et al 2012).…”

One of the core focus areas in Saudi Aramco's effort to increase hydrocarbon recovery is in the application of extreme-reservoircontact (ERC) wells. These wells, with more than 20 km of reservoir contact, are needed to ensure fluid off-take points are distributed throughout the reservoir efficiently. Accurate sensing and control are crucial to the efficient sweep of heterogeneous formations. This paper describes a recent multilateral (ML)-well trial that validated a number of core technologies and methods required to make ERC a reality, including• Well construction and deployment practices to allow electrical umbilicals to be reliably deployed in openhole laterals• Deployment and testing of revolutionary low-power, infinitely positioned electric flow-control valves (FCVs) designed to be deployed in each compartment in an openhole segmented lateral completion• Validation of the fully integrated onboard-production-monitoring system providing direct downhole measurements of pressures, temperatures, flow rates, and water cut for each controlled compartment• Integration of the surface acquisition and monitoring system to the production supervisory-control-and-data-acquisition (SCADA) system to provide real-time downhole production information, as well as valuable system-health-status data that can ensure operational integrity during the life cycle of the well An ML well close to the oil/water-contact point was allocated to validate the functionality of two prototype systems installed and has provided valuable reservoir data for more than 1 year of production. The well trial successfully demonstrated the ability to install and retrieve an umbilical completion from a 10,000-ft horizontal lateral. The ability to control downhole flow to within a few barrels per day measured at the reservoir face is proving revolutionary to the way the operator will approach future reservoir management. The sensing system will be capable of delivering continuous compartment productivity. The SCADA integration allows for a real-time management function such that the compartment can be controlled to a target off-take rate directly, without resorting to the use of traditional well-system models for estimating control settings. This paper highlights the objectives, installation, validation, and functional aspects of this new ERC well system, as well as identifying some of the immediate production effects emerging from this level of visibility and control at the formation face.
