Tech Paper: Improved Completion Economics Through Real-time, Fiber Optic Stimulation Monitoring

Successfully installed single fiber-optic equipped well provides useful feedback on completion designs This paper demonstrates how a single permanent fiber installation allowed the development of improved completions designs in real time in order to improve well economics. Design changes were adjusted during the completion of the well to determine stage length and completion execution. Improvements were applied to the subsequent wells in the program. In 2018,...

Tech Paper: Evolution of Frac Plug Technologies – Cast Iron to Composites to Dissolvable

The impact of the evolution of the frac plug over the past 20 years A technological revolution in hydraulic fracturing has occurred between early wellbore stimulation techniques and present day stimulation that has reduced cost and increased stimulation performance. Part of this revolution has been driven by the improved technology of frac plugs. This paper discusses how the evolution from cast iron frac plugs to composite...

Tech Paper: Estimation of Capillary Pressure and Relative Permeability from Downhole Advanced Wireline Measurements for Waterflooding Design

New workflow developed to help estimate relative permeability and capillary pressure in downhole conditions Reservoir relative permeability and capillary pressure, as a function of saturation, is important for assessing reservoir hydrocarbon recovery, selecting the well completion method, and determining the production strategy because they are fundamental inputs to reservoir simulation for predicting lifetime production of a well. Estimation of relative permeability and capillary pressure curves at...

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...
