“…Examples of this include the leaking completion pipe in the Giant Offshore field located 84 Km NW of Abu Dhabi Island. Corrosive environments and the installation of inflow control devices (ICDs) of the nozzle type have resulted in a wear-through of the completion pipe in this field [ 4 ]. While studying this phenomenon, the authors gave the main recommendation to replace the grade of pipe material with a more corrosion-resistant one.…”

Existing approaches to assessing the reliability and safe operation of downhole equipment provide for assessing only the direct impact of erosion and corrosion processes on the degradation of the material. At the same time, the influence of downhole equipment operating modes on the intensity of corrosion and erosion processes is not evaluated. The necessity of using inflow control devices is shown. The necessity of selecting inflow control devices for specific operating modes of the well is highlighted in order to avoid increased erosion wear due to increased sand production. In this article, a series of studies was conducted to assess the influence of the hydrodynamic characteristics of the fluid flow, which vary depending on the operating modes of the nozzle-type inflow control device, on corrosion processes in the well. It was shown that the level of wall shear stress (WSS) of the base pipe, immediately after the flow control device in the direction of fluid flow, affects the intensification of corrosion processes in downhole equipment. Studies of WSS on the pipe wall were carried out using a dynamic autoclave and elements of mathematical modeling. The design factors (the angle of inclination of the main hydraulic channel of the inflow control device relative to the base pipe) affecting the change in tangential stresses on the wall of the base pipe were investigated. The mechanism of corrosion wear of the base pipe was revealed.

An integrated completion design modeling approach has been implemented for development wells in a giant offshore field to maximize asset value and recovery. The modeling approach enables the selection of lower completion inflow control devices and well path compartmentalization strategy for every well based on predefined criteria.The development of the field under consideration is progressing with a water flood recovery scheme that requires the use of new technologies to achieve higher oil recovery and controlled water production. Since the only contact with reservoir is the wellbore, efficient reservoir sweep and recovery can only be achieved by putting the right well equipment in the right location.In this paper, the design process which has been adopted for well completion design using Inflow Control Devices (ICDs) will be shared and explained. An interactive loop is used to optimize the number of ICDs and nozzle sizes using reservoir simulation coupled with specialized well and completion modeling software.A number of ICD well completion design examples are presented. From these examples, predefined design criteria are applied in an iterative manner targeting optimal sweep and maximum recovery as an objective function. The key criteria elements are:• Predicted water flow mechanism from nearby injectors into the well. • Reservoir pressure contrast along the well path and variation over time to account for additional pressure drop imposed by ICDs. • Permeability contrast along the well path. • Effect of nearby producers, if within the same drainage area.When concluding the detailed completion design, the outcome is shared with the Drilling operation team for fine-tuning, materials selection, materials procurement, and implementation. Further modeling work will be discussed covering the impact of the stimulation design resultant skin on predicted recoveries.

For the last 30 years, wells in the field have been suffering from medium to high corrosion rates in both near surface and downhole components. Remedial measures had been implemented in order to restore Well Integrity with different techniques. Corrective actions aside, a strong preventive approach is needed to better understand the root causes of such corrosion rates and scenarios where the integrity of specific wells has been seriously compromised due to corrosion problems.Taking a step further and considering the big implications of new projects such as Artificial Islands project, where the company will be drilling & completing over 300 Extended Reach Drilling (ERD) wells, Well Integrity input as a discipline becomes critical in order to ensure previous problems will not be repeated and all lessons learned throughout the years will be wisely taken into consideration when designing a new well to remain integral during its whole expected life.Understanding of the current corrosion mechanisms in the field was the key to find not only solutions, but also, to create an approach aimed to improve the future completion for Island wells in terms of design, materials and many other factors.An extensive multidisciplinary approach was carried out in order to successfully complete a full study in one of the pilot wells completed with Inflow Control Devices (ICDs), which will be analyzed in detail in this paper, covering the following areas:i. Well design and configuration ii. Well monitoring and performance review iii. Well diagnosis and failure investigation iv. Post-Failure modelling and well prediction v. Preventive/Corrective actions for future wells. Corrosion management and prevention of scale deposits were the two main challenges encountered during this project, which was launched and completed with the main objective of evaluate and optimize the ICD completion design in one Maximum Reservoir Contact (MRC) pilot well in the field, the findings and lessons learnt were used to upgrade the current well design and improve the development plan for the field.
