Tech Paper: Reliable Detection and Power in an Electronic Sliding Sleeve Multistage Completion System

New electronic sliding sleeve helps increase flexibility, reliability, mechanical simplicity, and robustness for multistage hydraulic fracturing A new electronic sliding sleeve has been developed for hydraulic fracturing that provides the operational efficiency of sliding sleeves while enabling an unlimited number of fracturing zones and eliminating the milling of the baffle seat. This system uses electronic sensors and battery power to determine when the...

Tech Paper: Continuous Use of Fiber Optics-Enabled Coiled Tubing Used to Accelerate the Optimization of Completions Aimed at Improved Recovery and Reduced Cost of Development

Halliburton Helps Operator Increase Production by up to 25% with Fiber Optics-Enabled Coiled Tubing Continuous improvement in completions designs leading to an increased return on asset development is one of the primary focuses of operating companies. To continue driving towards this goal, an operator looked to continuously optimize completions designs in their acreage in Bakken, North Dakota. There were two parallel paths taken...

Tech Paper: Unconventional Multiplay Evaluation of Casing-in-Casing Refracturing Treatments

Halliburton successfully implements casing-in-casing refracturing treatments in the Haynesville and Eagle Ford Shale Throughout the development of major shale plays, a better understanding of stimulation influence on reservoir productivity has led to significant changes in industry completion practices. The relatively fast development of fields combined with the evolution of completion design suggests the completions performed on the earlier completed wells are understimulated and...

Tech Paper: An Integrated Formation Evaluation Approach to Characterize a Turbidite Fan Complex

Advanced integrated analysis helps reduce overall formation evaluation costs and saves rig-time The oil and gas potential of the basins surrounding the Falkland Islands has attracted exploration drilling that resulted in discovering the Sea Lion Field in the North Falkland Basin in May 2010. Recent exploration drilling has resulted in new oil discoveries to the south of the Sea Lion Complex that has...

Tech Paper: A New Ultra-deep Azimuthal Electromagnetic LWD Sensor for Reservoir Insight

New tool helps optimize well placement during the development of a reservoir In the development of a reservoir, optimizing the well placement in the desired formations from pre-well modeling techniques is a challenging task. Existing well-planning techniques, such as offset well logs or surface seismic data, do not provide the required level of accuracy and can result in high uncertainty in geosteering decisions. Conversely,...

Tech Paper: Saturated Salt and Diesel Emulsion Fluid Reduces Drilling Costs in New Mexico

Direct emulsion water-based drilling mud system helps operator overcome challenges In the Delaware Basin of New Mexico, shallower formations, such as the Salado, include halite and anhydrite layers followed by weaker formations in the Delaware Sands- (e.g., the Brushy Canyon). The fracture gradient difference between these two zones has typically required an intermediate casing string to seal off salt formations before reducing fluid...

Tech Paper: A New Logging-While-Drilling Azimuthal Density Sensor for Large Borehole – Gulf of Mexico

Unique service helps address formation evaluation challenges encountered in large borehole sizes In the current market, operational geology and geoscience asset teams have clear and aggressive financial reduction target that need to be met without compromising the formation evaluation (FE) requirements of a well construction project. Advances in drilling and completion technologies and practices for deep-water wells commonly require operators to drill larger borehole...

Tech Paper: Redevelopment of an Unconventional Oil Reservoir: Finding Unstimulated and Bypassed Reservoir Volume

Increasing oil production in a tight carbonate formation through re-stimulation opportunities This paper identifies re-stimulation opportunities in existing horizontal wells with existing multistage hydraulic fracturing to increase oil production in a tight carbonate formation, offshore Black Sea. Pilot candidates were screened and ranked through the following decision criteria described in this paper, coupling reservoir, production and completion parameters. Favorable pilot candidates were verified...

Tech Paper: Optimization of Recovery Using Intelligent Completions in Intelligent Fields

Completing smart wells with remotely controlled inflow control valves Throughout the previous few years, substantial attention has been paid to the usage of smart well technologies to help improve recovery, particularly with technological improvements and an increasing expanse of opportunities in more challenging and rewarding assets. The fundamental focus has been to propose and develop workflows that integrate several surface/subsurface sub processes and...

Tech Paper: Low-Rheology Thermal Cement Design for Long Lateral Production Casing: Case History from the Duvernay Formation

Improved cement slurry design helps maximize hydrocarbon production and net present value This paper presents the design challenges and improvements made to cementing long lateral wells in the Duvernay formation. Low-rheology thermal cement slurries were designed and successfully pumped in more than 30 production jobs. These new designs were coupled with a lower-modeled pumping pressure at higher flow rates that were previously unattainable...
