Khafji offshore field, located in the Arabian Gulf, contains an unconsolidated sand reservoir subdivided into two, upper and lower reservoirs. Upper sandstone reservoir has relatively low reservoir pressure utilizing gas lift to help wells achieve production target rate. The main obstacle in upper reservoir is water encroachment due to unfavorably high-water mobility compared to oil; which presents a reservoir management challenge in the form of curbing water production linked to relatively high-permeability sandstone reservoir. In upper reservoir, water encroachment is dominated by active edge-water drive and it has irregular water-front movement because of the presence of high permeability streaks.Excessive water production from the high permeability upper sandstone reservoirs causes major economic, operational, and environmental problems during oilfield operations. Water production can also cause secondary problems such as sand production, corrosion, emulsion, and scale formation. Although the reservoir has been on production more than 50 years, water sources are still considered to be a mystery. Many different concepts and scenarios have been considered such as channeling behind the casing, highly conductive faults, channeling through the high-permeability zones and high-permeability streaks, which accelerated water production. As a result of this issue, water breakthrough at crested wells in an edge-water driven upper reservoir and water production has increased. Inflow Control Devices (ICD) completion has been installed in upper reservoir wells to overcome water production challenges. Low reservoir pressure is a major challenge for upper reservoir wells ICD completion design. During the course of this paper, Khafji field water encroachment study results have been discussed to show the latest water front movement expected scenario. In addition, ICD-completed wells performance was analyzed and compared to cemented perforated liner completion wells (Non-ICD completion) offset wells in upper reservoir. The parameters that were used during the ICD-completion design to overcome the main field challenges were highlighted. ICD completed wells showed positive performance results in water production control and higher oil production rate.

Inflow control devices, or ICDs, have been developed to improve well performance and enhance reservoir management by mitigating undesired water and/or gas breakthroughs that often occur due to a variety of factors, including: a). reservoir permeability heterogeneity; b). heel-toe effects - significant wellbore pressure drop from toe to heel; c). different reservoir pressure in different regions penetrated by a well. Success of an ICD completion relies heavily on appropriate design of the completion. Several key issues that should be addressed in designing an ICD completion have been identified and their impacts on performance of a well equipped with ICDs will be elaborated through a couple of case studies after a brief introduction of the three major types of inflow control devices (ICD). Practical guidelines for applying an ICD completion for reducing water production will also be shared. Several important observations have been achieved through this study:Appropriate design and planning for an ICD completion requires: a). good knowledge of reservoir and geology, such as permeability, porosity, reservoir pressure, as well as oil/water saturation distribution, etc; b). accurate modeling of the near wellbore fluid flow and flow in the completions; c). reasonable account for the change of reservoir condition over time - possible coupling between completion simulation software with a reservoir simulator is preferred.Zonal isolation plays a critical role in the success of an ICD completion, especially in terms of water production reduction.ICDs have been mainly developed to minimize toe-heel effects and balance inflow. Under certain circumstances, nontrivial water production may be anticipated from a well from day one of the well production. An ICD is not expected to trim much of water production from this type of well since water is already there, unless additional measures are taken to cut down water production.There are potential approaches for minimizing water production in well with ICD completion, such as:Change well trajectory to avoid high water saturation region(s);Apply ICDs with efficient phase filtering capability;Block water production with efficient zonal isolation.A reasonable design of ICD completion may have promising potential to cut water production as long as good zonal isolation across layers and sections exists; however, water production may also be cut with other completion options without ICD under the circumstances.

Carbonate Wells Stimulations by Acidizing Through Inflow Control Devices for Sredne-Sercheyusskoe Anticline of Yuzhno-Shapkinskoe Oilfield

In 2009, Lukoil installed inflow control devices (ICDs) in three horizontal wells in the Sredne-Sercheyusskoe anticline of Yuzhno-Shapkinskoe oilfield. The successful installation of the lower completion will describe the planning and design through detailed near wellbore modeling pre and post drilling. The latter used LWD measurements to update the model and redesign the completion to address the actual wellbore heterogeneity to optimize future production in terms of production acceleration and mitigation of more mobile fluids through inflow balancing. In addition, to ensure production contribution from heel to toe through the use of an optimized ICD completion, an acid treatment was also executed in two wells which further improved productivity of the well by successfully removing formation damage and possible debris barrier plugging. The ICD completion offered a means to balance the outflow of acid distribution across heterogeneous wellbores. The predesign acid job and post analysis will be presented and discussed.
