“…The bottom-up "trial and error" approach of evaluating multiple AFI designs has been used by previous workflows , Al-Qudaihy et al, 2006, Das et al, 2012. By contrast, our top-down approach is a fast workflow that uses the Average Annulus Pressure Difference Ratio (AAPDR) from a single reservoir simulation of an "ideal" AFI completion to design an AFI configuration with a realistic number of AFI devices.…”

Advanced well completion with multiple, downhole flow control devices such as Inflow Control Devices (ICDs), are a proven and effective solution to mitigate water/gas breakthrough and coning problems in horizontal and multilateral wells. An important parameter adversely affectinthe ICD completion's performance is the annular flow. Such annular flow can be minimised or eliminated by segmenting the wellbore into a number of compartments by installing Annular Flow Isolation (AFI). Installation of sufficient AFI at the optimum locations is a key step in achieving the desired well performance. This number of AFI devices is itself constrained by both costs and risks associated with installing the completion string in a long wellbore of complex geometry. Previous AFI design workflows were based on either a single well parameter or a static well-reservoir model that do not consider the total lifetime benefits of the technology. A new AFI design methodology that accounts for the well's lifetime performance has been developed to ensure optimal AFI design in terms of the location and number of AFI installed along the length of the completion.This novel workflow is based on the concept of, to a degree, mimicking the inflow performance of an "ideal" completion (i.e. the completion where AFI is installed between every 12 m completion joint) with a reduced, realistic number of AFIs. The great advantage of this workflow to optimise the AFI design is that it is based on the well's lifetime production performance while at the same time limiting the computation to a single reservoir simulation run for each number of AFIs. The workflow achieves this by ranking the AFI locations based on a criterion related to the annular pressures. A significant recovery increase can be achieved for wells designed with this new workflow when compared to previously proposed AFI design protocols. The learnings from this study can thus be employed by well engineers to optimally design advanced well completions.

“…(2) Enhance control over zonal production in comparison to completion scenarios where laterals are kept open hole or completed with just single-type FCDs such as only passive or only autonomous flow control devices. Several successful real-world applications of well completions incorporating multiple types of flow control devices have been reported worldwide e.g., [35][36][37][38][39][40].…”

There has been a tendency in oil and gas industry towards the adoption of multilateral wells (MLWs) with completions that incorporate multiple types of flow control devices (FCDs). In this completion technique, passive inflow control devices (ICDs) or autonomous inflow control devices (AICDs) are positioned within the laterals, while interval control valves (ICVs) are installed at lateral junctions to regulate the overall flow from each lateral. While the outcomes observed in real field applications appear promising, the efficacy of this specific downhole completion combination has yet to undergo comparative testing against alternative completion methods that employ a singular flow control device type. Additionally, the design and current evaluations of such completions are predominantly based on analytical tools that overlook dynamic reservoir behavior, long-term production impacts, and the correlation effects among different devices. In this study, we explore the potential of integrating various types of flow control devices within multilateral wells, employing dynamic optimization process using numerical reservoir simulator while the Grey Wolf Optimizer (GWO) is used as optimization algorithm. The Egg benchmark reservoir model is utilized and developed with two dual-lateral wells. These wells serve as the foundation for implementing and testing 22 distinct completion cases considering single-type and multiple types of flow control devices under reactive and proactive management strategies. This comprehensive investigation aims to shed light on the advantages and limitations of these innovative completion methods in optimizing well and reservoir performance. Our findings revealed that the incorporation of multiple types of FCDs in multilateral well completions significantly enhance well performance and can surpass single-type completions including ICDs or AICDs. However, this enhancement depends on the type of the device implemented inside the lateral and the control strategy that is used to control the ICVs at the lateral junctions. The best performance of multiple-type FCD-based completion was achieved through combining AICDs with reactive ICVs which achieved around 75 million USD profit. This represents 42% and 22% increase in the objective function compared to single-type ICDs and AICDs installations, respectively. The optimal settings for ICD and AICD in individual applications may significantly differ from the optimal settings when combined with ICVs. This highlights a strong correlation between the different devices (control variables), proving that using either a common, simplified analytical, or a standard sequential optimization approach that do not explore this inter-dependence between devices would result in sub-optimal solutions in such completion cases. Notably, the ICV-based completion, where only ICVs are installed with lateral completion, demonstrated superior performance, particularly when ICVs are reactively controlled, resulting in an impressive 80 million USD NPV which represents 53% and 30% increase in the objective function compared to single-type ICDs and AICDs installations, respectively.
