Tech Paper: Maximizing the Life of the Well Through Successful Cementing Technologies in Thermal Wells

 High-performance thermal self-healing cements prove successful in extreme conditions Reversing the natural process of pressure decline in hydrocarbon deposits and decreasing damage in the sandface caused by drilling, production, etc. are the most significant operator objectives for maximizing the extraction of hydrocarbon reserves. This paper discusses the successful application of cementing technologies in thermal wells to maximize the life of the well. In areas,...

Tech Paper: Intelligent Completions Customized to Meet the Challenges of Malaysia Reservoirs: Work Flow and Case Histories

Improving intelligent completion designs helps operator reduce cost and improve productivity Intelligent well completions (IWC) have been installed in Malaysia since 2003, but only recently has this technology become widely accepted. This acceptance has resulted from recognition of values such as reduced capital cost, improved productivity, and increased ultimate recovery. Initial documentation on IWC capabilities was presented in 2012 (Masoudi et al. 2012)....

Tech Paper: Use of a Salt-Tolerant Friction Reducer Improves Production in Utica Completions

New salt-tolerant polymer helps to improve well cleanup and provide additional benefits to field operations As longer laterals are drilled in the Utica to maximize acreage cover, the stimulation treatments must still establish high pumping rates to effectively treat multiple clusters even within the stages out near the toe area of the lateral. Overcoming this additional pipe friction as well as using various...

Tech Paper: Learnings from Cementing the Deepest Expandable Casing under HP/HT Conditions in Mediterranean Offshore Egypt

The design and execution phases are important pieces when cementing under difficult conditions The adequate cementation of an expandable tubular can be challenging but is essential for long-term casing integrity. Such cementing jobs are especially crucial under high-pressure/high-temperature (HP/HT) conditions for many reasons, including but not limited to rigorous HP/HT laboratory testing schedules, selection of proper cement volume and fluid density, etc. A failed...

Tech Paper: Successful Application of Plug and Hydrajetting Technique during Multistage Fracture for Horizontal Wells with Coiled Tubing

Reducing NPT up to 30%, this Coiled Tubing method allows for continuous completion of fracturing stages This paper presents an alternative for operators regarding tools and methods using coiled tubing (CT) during the implementation of horizontal completions. To help address challenges faced developing horizontal completions, both cemented liners and open holes have been widely used in conventional and unconventional reservoirs. Various completion techniques have...

Tech Paper: Successful Utilization of E-line Tractor in Horizontal, High Pressure and High Temperature Gas Wells

This state-of-the-art technology helps meet the technical objectives of large rigless production enhancement Growing gas resource exploitation in Saudi Arabia has increased activity in drilling deep, high pressure gas reservoirs with marginal to low permeability. Such wells generally require stimulation operations to induce production. To increase the reservoir contact area, a significant number of wells are constructed with long reach horizontal sections. Multistage fracture...

Tech Paper: First Large-Bore Expandable Liner Hanger Deployment Offshore Gabon – Case Study

Technology helps improve reliability and increase versatility in deepwater operations The capability to reliably deploy large-bore hangers in offshore applications is critical to project success (McCormick et al. 2013). This case study discusses the the deployment of a large-bore expandable liner hanger (ELH) for the first time in a West African country and how the deployment of a 16-in. liner inside 20-in. casing at...

Tech Paper: Completion Design Optimization for Barnett Oil Producing Area

Focus on subsurface insight and collaboration are essential to helping discover and produce more oil and gas Throughout the past several years, economic and technological advancements in the North American shale market with respect to drilling and hydraulic fracturing operations have helped create a “typical” operating scheme for producing from the multiple shale formation reservoirs currently being exploited. This typical scheme focuses on...

Tech Paper: Pulling Subsea Wellhead Plugs Using a Slickline Downhole Electrical Power Generator Tool

Viable and cost-effective option in Gulf of Mexico deepwater environment A downhole electro-mechanical power-unit tool was used to provide anchored power to pull crown plugs in a single run and in reduced time. This setup has the capability to pull subsea crown plugs that often require greater force than is possible with traditional conveyances without requiring time and resources to reduce hydrostatic pressure....

Tech Paper: Refracturing Design for Underperforming Unconventional Horizontal Reservoirs

Comparison of different Haynesville shale refracturing design treatments, results, and diagnostics This paper discusses refracturing design considerations to increase the estimated ultimate recovery (EUR) on underperforming wells in a refracturing scenario. A method for, and case histories of, using an environmentally acceptable, self-removing particulate diverter that has proven to be successful in the refracturing efforts of horizontal unconventional reservoirs are provided. This method is...
