“…Seven weeks into production, the well continues to produce with less than 1% water cut. Given the producing bottom hole pressure of the well, the lower most SZI openhole packer is isolating water production with approximately 1,900 psi of pressure differential across the packer cup seals which is within the tested limit of 3,000 psi inside 10-3/8-in openhole (Hecker 2011). …”

Openhole gravel pack (OHGP) completions are often selected as the preferred completion technique to provide long life, high capacity, low skin completions. One drawback to OHGPs, however, is the inability to isolate undesirable water or gas within the completion interval whether it is identified during the initial completion or during any point in the production lifecycle of the well. With the recent introduction of a broad suite of Alternate Path ® Technology (APT) tools, the added functionality of true openhole zonal isolation can now be combined with the reliability of gravel packing to deliver unparalleled, long-term completion capabilities.With the advancement of the new openhole shunt packer with APT, wells have been successfully completed to provide capability for future isolation depending on production results of the well. The shunt packer can be run through 9 5 ⁄8-in casing, set before gravel packing begins, and form a seal against the borehole to provide annular isolation in either round or oval hole sizes up to 10¾-in. These openhole packers have been recently combined with shunted blank joints to provide upfront isolation of unwanted water or gas found while drilling the completion interval to increase well production rate and/or estimated ultimate recovery (EUR). This paper will describe the first installations of the equipment which combined internally shunted sand screens, openhole shunt packers, and shunted blank pipe to fully isolate water and gas sands within a completion interval while enabling a full gravel pack across the remaining completion.

“…Each method is effective in shutting off only specific water paths, and they could be classified into two types: Mechanical methods involve placing a tool of high mechanical strength or cement into the wellbore to shut off the unwanted water source. The mechanical tools involve retrievable and straddle packers, − plugs, tubing patches, and squeeze cementing. − They are preferred for treating near wellbore problems such as channels behind casing or casing and tubing leaks. The advantage of the mechanical methods is that the effect will appear in a short time and is relatively inexpensive compared to other solutions. , However, they are not feasible for treating reservoir-related sources such as fractures or high permeability zones .…”

Reducing water production from hydrocarbon wells is one of the major requirements to prolong the life span of production wells. Gel treatment is commonly regarded as one of the traditional cost-effective methods for water shut-off applications. Different gel systems have been developed to overcome the challenges of performing a successful water shutoff treatment. Each gel system has its advantages and disadvantages. A new proposed technology is to enhance the gel performance by utilizing nanomaterials in its composition. Nanomaterials such as nanosilica, nanoclay, and graphene can significantly modify gel properties to improve plugging efficiency. This paper provides a brief review of the added value of using nanomaterials in the structure of polymer in situ gel, preformed particle−gel, and nanosilica-based fluid. Nanomaterials such as nanoclay, nanosilica, and nanographene are capable of adjusting the properties of in situ gel, such as control of gelation time (9−10) hours and enhancing gel strength up to 4.5 times. Nanomaterials also improved the swelling ratio of the preformed particle−gel by up to 400%, accompanied by increased gel strength. Notably, nanosilica-based gels exhibit an exceptional plugging efficiency (100%). Additionally, the paper discusses how modeling can be used to overcome operational challenges in terms of placement and plugging performance.

Openhole completions are often selected as the preferred completion technique to maximize reservoir flow potential and provide reliable, high capacity, low skin completions. In many environments, these completions will also require some form of sand control. To meet development objectives, operators are continually challenged to select, design, and install fit-forpurpose completion strategies to optimize ultimate recovery for these fields. These challenges necessitated the creation of new practices, procedures, and hardware to ensure consistent delivery of reliable wellbores, across the entire organization, to achieve long-term, economic success.ExxonMobil embarked on a multi-year initiative to establish and sustain a disciplined, systematic approach to sand control completion design, job execution, and performance assessment. The effort included the development, qualification, and deployment of selective, enabling completion technologies. Additionally, comprehensive engineering and operational guidelines, as well as, in-depth training were delivered to the worldwide engineering and operations workforce. Most significantly, the initiative is now resulting in effective and rapid transfer of learnings and best practices across the global organization. This comprehensive effort continues to focus on ensuring the right people are deploying the right technology in the right well. This paper will discuss the guiding principles associated with our overall completion practices. It will also describe a number of enabling technologies pioneered by ExxonMobil including: • NAFPac SM , a gravel pack technique that allows the operator to run the gravel pack screens in non-aqueous fluid, gravel pack the well and displace the casing to brine, all in one trip • MazeFlo™, a self healing, redundant sand screen • Internal Shunt Alternate Path Technology (ISAPT) screens with openhole shunted packers, a completion technique that enables true and selective zonal isolation in openhole gravel pack applications
