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 next stage of...

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 to a) reduce...

Case Study: Advanced Completion Solutions for Multizone Water Injection in Soft Sand

World’s First 10,000-psi Triple-zone Intelligent Completion For Water Injection Challenges – A major operator in the Caspian region required pressure support and sweep efficiency for enhanced recovery of a massive offshore oil field. Previous attempts at multizone, high-rate water injection in this soft sand field had mixed results with non-conformance injection profiles and loss of sand screen integrity, leading to sand infill and premature loss of...

Inflow Tech® Packer Enables Operator to Identify Liner-top Leaks in Long and Complex Big-Bore ERD Well

Packer Performs Successfully in Single Trip, Saving Operator Millions of Dollars in Blowout Avoidance Challenge – This was the longest well that the operator had drilled in the region and the most complex in terms of architecture. The well construction consisted of 12,831 feet (3,911 meters) of mixed 13 5/8-in. and 13 3/8-in. casing, as well as 13,330 feet (4,063 meters) of 9 5/8-in. liner. The...

Halliburton Installs 300th FlexRite® System, Including Over 100 FlexRite MIC Junctions, In North Sea

FlexRite MIC Junctions Enable More Advanced Multilateral Completions Challenge – Back in 2012, the operator required a solution for achieving new levels of zonal control in its multilateral wells. Traditionally, many multilateral wells have consisted of multiple branches commingled in a completion solution that provides greatly increased reservoir exposure, but with limitations on control over individual branches and zones. A new completion solution was required that...

Don’t Get Stuck On Defense: Learn How Some Operators Are on the Offensive against Frac Hits

With many unconventional basins shifting from exploration and leases to infill drilling, a topic of major concern is now “well bashing” — when frac fluid of an infill child well infiltrates the wellbore of a nearby parent well. Over the past few years we’ve seen parent-well production decrease, requiring costly workover operations to regain production targets. This well basing problem is compounded when localized depletion from...

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 inadequate for optimum...

Case Study: Single-Trip Multizone Cased-hole Frac Packs and Intelligent Completions Improve Recovery in Subsea Gas Field

Advanced completion solution enables wells to remain fully functional after five years of production Challenge – The operator needed to improve operational efficiencies for this complex subsea field of shallow, low pressure, and weakly consolidated gas reservoirs. The field required a method of dealing with unconsolidated sands, along with the ability to monitor and control each of the six potential layers as the economics of the...

Case Study: Integration Drives Performance and Accelerates Learning Curve in an Ultra-Deepwater Pre-Salt Exploration Drilling Project in Brazil

Halliburton integrated services achieves new benchmarks in post-salt and salt sections Challenge – The operator faced many challenges to build exploratory wells in this ultra-deepwater environment, with the main objectives to minimize the significant drilling risks and costs and reduce the total cost of well construction and evaluation. Other challenges included the long 28-inch riserless section in the post-salt formations facing hole instability issues and high...

Case Study: eRED® Valve Provides Efficiencies and Time Savings in Downhole Operations

Valve operates remotely after 23 months down hole Challenge – The operator’s previous method for hanger installation and completion testing involved the deployment of a dual-bore riser and multiple intervention runs to allow for plug installation on the annulus bore. This can be a time-consuming operation, especially as the North Sea is subject to adverse weather conditions that can result in waiting on the weather to...
