“…COMPLETION Lorenz et al (2006) conducted production simulations with and without ICD within an 8.53 m horizontal wellbore and compared the annular flow under the two conditions. Their experiments showed that in actual production, if the flow profile of the horizontal section is unevenly produced, the horizontal section of slotted screen completion and ICD completion will contain the variable mass flows of the center tubing and the annulus, as shown in Fig.…”

A flow is observed in the pipe for the horizontal section of slotted screen completion and inflow control device (ICD) completion, and an annulus flow exists between the pipe and the borehole wall. Based on the principles of mass conservation and momentum conservation, a model for variable mass flow in an oil reservoir to simulate wellbore–annulus–reservoir state in the horizontal section of slotted screen completion and ICD completion is proposed. Consequently, based on the newly established formation transient seepage model and wellbore and annulus variable mass flow model, an accurate prediction of the production rate of a horizontal well as well as optimized design parameters for slotted screen completion and inflow control device (ICD) completion are achieved. The predicted flow profiles of the established model are confirmed using the simulation software from Computer Modeling Group Ltd. When external casing packers are not considered, findings show that the predicted production rates of both slotted screen completion and ICD completion, which are obtained using the variable mass flow models without annulus flow modeling, are higher than the rates obtained using the variable mass flow models with annulus flow modeling. Both models show that the pressure profile and flow profile of the borehole wall are more uniform in wellbore–annulus–reservoir in horizontal wells. The flow model for horizontal wells with annulus flow modeling should be established to improve the accuracy of the predicted production.

“…The ICD device, as an advanced completion technology developed since late 1990s [1][2][3] , introduces the extra pressure drop to effectively balance the inflow contribution along the long horizontal wells and prolong the water/gas breakthrough time. ICD completion design includes the coupling computation of reservoir percolation, wellbore flow, and ICD pressure drop.…”

ICD completion has been rapidly developed due to its effective mitigation of unwanted water breakthrough in horizontal wells. It prolongs the no-water production time by introducing an extra pressure drop in high inflow rate zones. With respect to the horizontal well, equally distributed influx is generally regarded as the ideal influx to achieve the longest no-water production period. Howeverin some cases, like producing with fixed bottom-hole pressure (BHP), this may not always correct. When designing the ICD completion, the target inflow profile should be carefully selected. The horizontal well needs to be selectively completed with variable ICDs to minimize the reduction of well productivity.In this paper, a reservoir-wellbore coupling model will be given for influx computation, in which the ICD pressure drop is considered. Then we will propose the selection principle of the target inflow profile for ICD optimization on the constraints of BHP limits, required daily production and no-water production periods. The cumulative production at the time of water breakthrough is selected as the evaluation criteria. The flowchart of the ICD optimization process for the heterogeneous reservoir will be illustrated; and a synthetic case study will be carried out with a comparison of open-hole completion, constant ICD completion and optimal ICD completion. Results indicate that the effect of the water control of ICD completion can be maximized with a reasonable selection of the target inflow profile.

With improvements in technology and increasing amount of opportunities in more challenging assets, the use of smart well technologies to improve recovery has caught significant attention in the oil and gas industry in the last decade. Several workflows have been developed and proposed in order to automate the whole process that integrates several subprocesses focusing on specific parts of the surface or subsurface phenomena. Reservoir sweep is a crucial part of recovery efficiency, especially where significant investment is done by means of installing smart wells that feature inflow control valves (ICVs), which are remotely controllable. However, as it is a relatively newer concept, effective use of this technology has been a challenge. In this study, the objective is to present the efficient use of ICVs in intelligent fields to maximize sweep, and thus, recovery tied to the objective function. A standard realistic SPE reservoir simulation model of a waterflood process has been used where the smart well ICVs are controlled with conditional statements, called procedures, in a fully-commercial full-physics numerical reservoir simulator. Key performance indicators, including but not limited to water cut and oil rate, are used to adjust the degree of opening of ICVs on the producer side to balance injection on the injector side. This turns out to be a complex phenomenon of higher degree of nonlinearity in a multi-well system in a large field where several wells interact with each other. Objective function seeks to maximize the net present value (NPV) of cumulative oil recovery. Smart well technologies have been challenged with the associated cost component, thus, it is important to present the benefits of this technology with applications on more diverse cases showcasing different workflows. It has been observed that robust reservoir management in an intelligent field can significantly improve the sweep and recovery by utilization of smart wells with ICVs. The results are presented in a comparative way against the base case to illustrate the incremental value of use of ICVs, along with key performance indicators. Most importantly, it has been shown that the use of smart wells without a robust reservoir management strategy does not always lead to successful results. In reservoir management, it is not only important to catch the well level details but also to see the big picture at field level for improving reservoir performance beyond individual well performances, taking into account the interference between wells. Although smart wells with ICVs have been deployed on wells all over the field, unfortunately, some similar studies mainly focus on individual or near-wellbore performance rather than the whole asset. In this study, a field-wide approach is followed that integrates data from key performance indicators in an integrated workflow, which outlines efficient integration of variables available to optimize recovery.
