“…In high risk areas, the well is completed with inflow control devices (ICDs) to evenly distribute production contributions along the pay zone; accordingly, this improves the oil sweep and defers the premature water enchroachment. 9,10 For instant, well-B was drilled and completed as a horizontal open hole producer at the top of the reservoir in a mature location. The well showed a rapid water cut increase and ceased to flow at the water cut above 70%.…”

Water management practices are an integral part of effective well and reservoir management to avoid various water production problems. Water production problems are major challenges in the oil and gas industry. Many strategies have been used in the industry to control water production problems both in producers and injectors. There are many water control methods available in the industry, including mechanical and chemical methods; sometimes a combination of both methods is used.With the advent of horizontal drilling technology, unique opportunities have been captured to enable efficient and effective water management. More complex wells of various types and shapes have been drilled and completed. The benefits of drilling these wells not only include reduction in development and operating costs because of the lower number of wells but also improvement in the reservoir performance and management of fluid movements. These complex wells are drilled for various and many objectives, which may include but are not limited to increased production, enhanced reservoir characterization, improved sweep, maximized recovery, and efficient reservoir management.Water management practices implemented for effective water control, and to sustain oil production on two different areas in a major field are presented in this paper. One area exemplifies water management practices in a conventionally developed field, and the second area represents drilling conformance technology, utilizing smart MRC wells.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractDrilling horizontal wells has become the more commonplace in many Saudi Aramco fields. Recent advances in drilling and completion practices enable the drilling of more complex wells with various types and shapes such as extended reach wells, bi-laterals and multi-laterals for providing maximum reservoir contact. These complex wells impose great challenges with respect to rigless well interventions. One of the initial well interventions, which follow drilling completion, is acid stimulation to remove formation damage. The challenges raised because of well complexity include accessing the laterals, reaching the end of each lateral and properly distributing treatment fluids over entire horizontal sections.Effective rigless interventions in these challenging wells have limitations and technologies are still evolving. Deployment of tools and fluids downhole is no more possible through conventional coiled tubing applications. New techniques have been developed to assist coiled tubing (CT) to access laterals and extend their reach. In addition, recent advancement of CT bottom-hole assembly (BHA) allows combining services of more than one function such as deploying tools and fluids and at the same time acquiring vital downhole data.

With the advancement of technology and ease of drilling horizontal wells, producers/injectors are drilled with thousands of feet of horizontal section, to expose large reservoir areas for higher production/injection. To have a better flow distribution profile in heterogeneous formations, the producers/injectors are completed with Inflow Control Devices (ICDs) and external packers that provide compartmentalization to flow. The permanently installed distributed temperature sensing (DTS) fiber optic cable is externally attached to the completion, which is fed through the packers. This helps in obtaining distributed temperatures of all formations along the wellbore and throughout the horizontal section with high resolution. On-site analysis of the real time data from DTS could be used to optimize well treatments, such as acid stimulation. This paper presents in depth analysis of an acid stimulation performed on a power water injector in a carbonate reservoir. The well is completed with ICDs, DTS and a Permanent Downhole Monitoring System (PDHMS) for well and reservoir monitoring. The real time data acquisition of distributed temperatures coupled with online interpretation through a special software helped in building temperature profiles. Analyses of the temperature profiles were used for proper placement of acid and diverter stages. The post acid stimulation result was very encouraging with a significant increase in the well injectivity and even flow distribution along the horizontal section. The experience obtained from this job has been used as a basis for future stimulation jobs.
