Case Study: Halliburton Formation Evaluation (FE) Program Helps Client Discover More than 400 Feet of Net Pay

Safe, Efficient Operations Collected the Required Data in 17 Days Across Two Wellbores Challenges – The customer needed to obtain high-quality formation evaluation, rotary cores, pressures, and fluid samples in two large open holes. The requirements included performing reservoir characterization and rock evaluation for whole-core calibration, and collecting lab-quality samples and accurate reservoir pressures for reservoir quality and structure. Time constraints would need...

Case Study: Halliburton Installs World’s First 9 5/8-inch Multibranch Inflow Control System in North Sea

New TAML Level 5 FlexRite® MIC System Enables More Possibilities for Advanced Multilateral Completions Challenge – In March 2017, a Norwegian operator approached Halliburton, needing a new TAML Level 5 multilateral technology (MLT) solution for its mature field in the North Sea. While the operator had been using Halliburton MLT technology successfully for many years in this field, its use was limited to...

Case Study: Innovative Elect® Frac Sleeve System Proves Successful for Demanding Well Conditions

‘First of a Kind’ Sleeve System Enables Complex Completions and Minimizes Risk Challenges – Rockcliff Energy was interested in a frac sleeve system without operational pressure limitations to allow for higher circulating and cementing rates, and to help eliminate the risk associated with wellbore packoff and the inadvertent shearing of pins. A further limitation with conventional toe valves is determining an ideal pinning...

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...

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...

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...

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...

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...

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...

Case Study: eRED® Valves Save 88 Hours of Rig Time for Upper Completion Project

Remotely operated valves eliminate requirement of costly interventions To achieve its goals, Shell elected to pre-install the remotely operated Halliburton eRED® valve as a shallow barrier in the tubing hanger. This allowed Shell to have a secondary barrier in place without the requirement of an intervention before removing the blowout preventer (BOP) and installing the Christmas tree. In total, the eRED valves were...
