Case Study: Halliburton Enters Conventional Liner Hanger Market on Sinclair Well

First MatchSet™ system is successfully installed in highly deviated horizontal application Challenge – The customer had limited operations in the Williston Basin, and was faced with the complexity of a highly deviated horizontal well with a sidetrack. It needed a hanger with a modular design that could handle long and heavy liners with minimal stress to the parent casing. The MatchSet™ conventional liner...

Case Study: BaraShale™ Lite Fluid Enables Sustained Success of Unconventionals in Low-Cost Oil Environment

New water-based fluid system helps operators save time and reduce costs Challenge – With its unconventional field developments, the outstanding success of the Permian Basin as a global oil and gas swing producer has been sustained by operators and service companies using innovative technologies and cost-efficient operational practices. Overlying much of the hydrocarbon-rich Delaware Basin – the western province of the Permian Basin...

Case Study: Project Management Service Utilizes Technologies to Deliver Wells Ahead of Schedule

Multi-team solutions improve drilling efficiencies, saving average of 72 days of rig time Challenge – Formation problems along with drilling complexities were causing time delays and high costs for the customer. Halliburton was asked to implement its technologies, engineering services, and experience to optimize drilling and increase efficiency for the operator, as well as to unite its services and subject matter experts, through...

Case Study: Operator Identifies Shallow Surface-Casing Corrosion Without Costly Workover

Halliburton Electromagnetic Pipe Xaminer® V (EPXTMV) tool detects metal loss near wellhead Challenge – Since the operator’s leak was impacting production, and similar wells in the area experience shallow surface-casing corrosion problems, the operator wished to know the extent of this potential problem to develop a remediation plan. Solution – Halliburton recommended assessing the corrosion using the new Electromagnetic Pipe Xaminer® V (EPX...

Case Study: Boots & Coots Successfully Controls Well Release in Remote Field

Team solves challenging logistics to control gas release prior to well abandonment Challenge – The operator contacted Boots & Coots after a gas leak through one leg of the completion string was reported. Well control specialists were immediately mobilized to the location, and they performed the initial site inspection while simultaneously organizing a well control response plan for the incident. The main obstacle for organizing...

Case Study: SentinelCem™ Cement Cures Losses in Iraq Wells

Cement treatment saves operators millions of dollars annually Challenge – For years, operators drilling in the Rumaila, Zubair, and West Qurna fields in southern Iraq have routinely experienced severe and even total circulation losses at depths of 450–750 meters (1,476–2,461 feet). Underlying these fields is the karstified dolomite of the Dammam Formation, which has geological characteristics that include caverns, vugs, and large fractures....

Case Study: Operator Achieves More Reservoir Insight Using a New Azimuthal Gamma Ray Service

Azimuthal gamma-ray images uncover stratigraphic features in a seemingly featureless unconventional reservoir Challenge – Unconventional resources are often costly to produce as a result of the need for hydraulic fracturing. In order for these shale plays to be considered economical, drilling costs must be kept to a minimum, and many operators drill and geosteer wells with only average gamma-ray measurements obtained from a...

Case Study: PetroGuard® Openhole Shunt System Ensures Gravel-Pack Success for TOTAL’s Four-Well Batch Completion

Shunt contributed to 100 percent pack efficiency despite challenging openhole conditions CHALLENGE – TOTAL performed several internal studies to determine the most appropriate lower completion solution for its wells. It was identified early on that the four-well campaign required openhole gravel packs to successfully retain and control the formation sands. Additionally, hydraulic simulations were performed and sensitivities were used to assess the potential...

Case Study: Well Construction Performance Shaves More Than Eight Days Off of Plan in Rumaila Field

Solution optimizes drilling time while lowering costs CHALLENGE – Halliburton was challenged to design, drill, and deliver wells in the Rumaila field – and to do this safely, efficiently, on time, and within the allocated budget. The geology in the field presented significant obstacles, including losses within naturally vuggy or fractured formations, challenges of drilling through highly reactive shale sequences with borehole instability...

Case Study: Operator Successfully Runs 5 ¾-inch Slim-Hole Drilling Operation with Geo-Pilot® RSS System

Innovative solution drills one of the longest slim sections (5,500 feet) on Norwegian Continental Shelf CHALLENGE – In the previous operation of this ERD well, an expandable liner had been set to address formation instability. This expandable liner created a challenge, since the liner’s internal diameter was only 5.795 inches, which is extremely narrow. The wellbore’s narrow opening required a slim-version drill bit...
