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 project management, to...

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 V) tool. The...

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 with conventional designs....

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 and executing any...

Tech Paper: Wellbore Placement in the Middle Bakken Formation Using an Azimuthal Gamma-Ray Measurement

Identify shearing or faulting early using an azimuthally sensitive natural gamma-ray tool The Bakken formation is a large, unconventional resource located in North Dakota. Horizontal wells are drilled from pads at tight spacings, and placement within the target formation is critical to ultimate recovery rates. Geologic placement is established by evaluating the natural gamma-ray tool response and comparing it to a representative gamma-ray log from a...

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. Encountering these voids...

Tech Paper: First Successful Cuttings Reinjection CRI Operation in Ecuador: An Alternative to Help Minimize the Environmental Impact in a Protected Area

Fully integrated process represents permanent drilling solution in environmentally sensitive areas This paper discusses a technology for waste management and disposal through cuttings reinjection (CRI). The fully integrated process was successfully applied in the Ecuador Apaika-Nenke field, which is an area with significant oil potential located in the heart of a protected biodiverse zone. The advantage of the applied process, from candidate selection screening to the...

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 logging-while-drilling (LWD) tool....

Tech Paper: Mapping the Bakken with Azimuthal Gamma Ray

New, cost-effective measurement allows for better unconventional well placement in difficult-to-interpret situations This paper defines current geosteering practices in the Middle Bakken formation using conventional gamma-ray detectors and discusses the use of a new azimuthally sensitive gamma-ray sensor for more accurate well placement in the target formation. Two wells were drilled in the Middle Bakken formation using both a conventional gamma-ray detector and a new azimuthally sensitive...
