Production and injection in long reach horizontal wells pose several challenges in production optimization, flow assurance and reservoir management. Horizontal wells are known to be superior to vertical wells in terms of productivity, however, they are also susceptible to early water and/or gas cut production due to the heel-toe effect and/or permeability contrasts. Uniform distribution of water injection into all zones can also be a challenge in case of high-permeability streaks and fractures. To negate some of the adverse reservoir properties and to control the flow profile of production and injection fluids, downhole flow control devices are increasingly in use and beneficial in regulating flow, improved overall reservoir sweep, improved productivity from the tail section of the well and reduced water coning or gas cusping. Wellbore hydraulics for a long reach well completed with downhole valves have great influence on the reservoir performance and recovery in the long run. This paper presents a discussion aimed at better understanding of the critical challenges that long reach horizontal wells are prone to in terms of completion, as well as the developments so-far that have been applied to capture the physics across the long horizontal section. Three case studies are also discussed with some details emphasizing practical experiences of such wells.

“…Currently, there are three primary types of passive ICD designs in the industry: the nozzle based type (Bernt and Geir, 2009), the helical channel type (Jason et al, 2007), and the tube type (Kim et al, 2011). They use the restriction mechanism (the nozzle based type), the friction mechanism (the helical channel type), or cooperating both the mechanisms (the tube type) to generate the similar pressure drop.…”

In long horizontal wells, early water or gas may breakthrough into the wellbore due to the imbalanced production profile caused by the heel-toe effect, reservoir anisotropic, reservoir heterogeneity or fractureexisting. Once coning occurs, oil production may severely decrease due to the limited flow contribution from the non-coning regions. Inflow control devices (ICDs) are installed to maintain the flow across production zones uniformly by creating an additional pressure drop which cancels out the imbalanced production profile.Since a typical well with ICDs can be in production from 5 to more than 20 years, the long-term reliability of such a device is crucial to the well's overall success. Therefore, the ICDs must exhibit certain performance features during every phase of the well's life, however, the reality is that none of current ICDs alone meet the ideal requirements of an ICD designed, and current ICD selection for a specific reservoir mainly depends on the qualitative awareness of both the reservoir condition and the ICD performance.To make a better selection of the ICDs, dynamic weight theory is introduced into the fuzzy evaluation, and analytic hierarchy process is used for reference, which make the weight of each evaluation index change with the reservoir condition. The optimal membership degrees of these ICDs with varying flow rate, fluid density, and fluid viscosity are first calculated and then compared, which help to develop the ICD selection pattern. With the help of the pattern, we can select the optimal ICD simply and quickly once the reservoir condition is determined, which has the best corrosion resistance and the least viscosity sensitivity.

“…Currently, various ICDs have been developed in the industry. , The ICDs use three types of mechanisms to generate an additional pressure drop: the restriction mechanism, , the friction mechanism, , and the incorporation of both mechanisms mentioned above. − Unfortunately, once water coning occurs, the ICD will promote water production, not restrict it.…”

Design and Performance of a Novel Autonomous Inflow Control Device

Due to geological complexity and the heel−toe effect, the production profiles of long horizontal wells are usually imbalanced, and as a result, premature water breakthrough is usually encountered. Once water breakthrough occurs, this phenomenon will reduce oil production. To maximize oil recovery, inflow-control devices (ICDs) are widely used to create a uniform inflow profile. To date, known ICDs cannot meet all the ideal requirements throughout the well's life. In this study, based on the combination of a successive restriction mechanism and water swelling rubber, a novel autonomous inflow control device is proposed. Then, the rules of oil−water two-phase flow through the novel design are studied by a numerical simulation based on optimized structural parameters, and the fluid property sensitivities are analyzed. Upon integration of the novel design into the test apparatus, flow tests are conducted. The influences of water content, inflow rate, and injection rate on the pressure drop are further analyzed to provide a guide to completion parameter optimization. The results demonstrate that the novel design has a simple structure. Its flow-resistance rating can be easily adjusted. Additionally, the design provides a significant oil and water resistance difference. The pressure-drop ratio of the water relative to oil can be up to 40. The design has a large crosssectional flow area, providing high plugging resistance and high erosion resistance. Moreover, the design is not sensitive to flow rate or oil properties and has a wide application range. Reservoir heterogeneity should be given more attention than the heel−toe effect when optimizing the completion parameters.
