“…The sleeves need to be shifted with coiled tubing [9]. Coiled tubing models, taking into account the actual well bore trajectory, were run for all wells in order to make sure that the desired sleeve could be reached and the necessary force of 1000 N can be applied to shift it.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractA fractured carbonate field is developed via Gas Oil Gravity Drainage in the upper layers and water flood in the deeper layers. Due to the injection of gas and water into this fractured reservoir, horizontal wells tend to gas or water out, impairing the matrix drainage process. Different well and reservoir management techniques are used to prevent this from happening or to control the inflow when it happens. One such technique is to segment the bare foot horizontal open hole section with swellable rubbers and create up to 6 discreet zones of inflow, separated by 3 1/2 " tubing. The inflow from each section is currently controlled by a coiled tubing operated sliding sleeve. In the future it is anticipated that control will be done using hydraulically operated sleeves.Up till November 2006 eight horizontal barefoot oil producers have been re-completed with swellable packers. This paper concentrates on water shut-off and addresses the design, installation risks and mitigation, the impact of zone shut-off on well production performance, and the actions taken to optimize the production of each well by logging the well and shifting the sleeves.

Horizontal wells have become the industry standard for unconventional and tight formation gas reservoirs. Because these reservoirs have poorer quality pay, it takes a good, well-planned completion and fracture stimulation(s) to make an economic well. Even in a sweet spot in the unconventional and tight gas reservoir, good completion and stimulation practices are required; otherwise, a marginal or uneconomic well will result. But what are good completion and stimulation practices in horizontal wells? What are the objectives of horizontal wells and how do we relate the completion and stimulation(s) to achieving these goals? How many completions/stimulations do we need for best well performance and/or economics? How do we maximize the value from horizontal wells? When should a horizontal well be drilled longitudinally or transverse? These are just a few questions to be addressed in the subsequent paragraphs. This paper focuses on some of the key elements of well completions and stimulation practices as they apply to horizontal wells. Optimization studies will be shown and used to highlight the importance of lateral length, number of fractures, interfracture distance, fracture half-length, and fracture conductivity. These results will be used to discuss the various completion choices such as cased and cemented, open hole with external casing packers, and open hole "pump and pray" techniques. This paper will also address key risks to horizontal wells and develop risk mitigation strategies so that project economics can be maximized. In addition, a field case study will be shown to illustrate the application of these design, optimization, and risk mitigation strategies for horizontal wells in tight and unconventional gas reservoirs. This work provides insight for the completion and stimulation design engineers by: 1. developing well performance and economic objectives for horizontal wells and highlighting the incremental benefits of various completion and stimulation strategies, 2. establishing well performance and economic based criteria for drilling longitudinal or transverse horizontal wells, 3. integrating the reservoir objectives and geomechanic limitations into a horizontal well completion and stimulation strategy, and 4. identifying horizontal well completion and stimulation risks and risk mitigation strategies for pre-horizontal well planning purposes.
