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 and the rotary...

Case Study: Illusion® Frac Plug Helps Operator Save $200,000

All 15 plugs dissolved, removing the need for coiled tubing millout CHALLENGE – In an ongoing effort to reduce the risks and costs incurred when completing a well using the plug-and-perforate method, the operator was primarily looking for ways to remove the need for milling out composite plugs. As an added challenge, the customer’s objective was to maintain the same parameters during the pump down and...

Case Study: Boots & Coots Regains Control of Platform After Five-Well Blowout

Team maintains stability of 30-well platform, contains blowouts, and safely caps wells CHALLENGE – The main concern was to maintain the stability of the platform, which was rapidly deteriorating due to prolonged heat exposure. Fortunately, some of the wells were producing via a gas lift process and, after the initial explosion, the operation could be shut down, extinguishing the fires on these wells. Now the fires...

Case Study: Operator Saves USD 7.2 Million with Improved Drilling Performance and Sets New Field Benchmark

DES helps operator reduce drilling with potential savings of USD 115 million across field CHALLENGE – These shallow-water wells were typically drilled in about 93–105 days because of many factors, such as trajectory management, bit selection, limited hole cleaning, and bit hydraulic power design. Thus, the rate of penetration (ROP) and the additional time spent for hole cleaning were not optimal. To keep its operations economically...

Case Study: Mobile Testing Package Enables Early Production

Mobile express surface well testing system helps operator achieve production goals in new fields CHALLENGE – Parnaíba Gás Natural S.A. operates in Maranhão State and is responsible for about 10 percent of all natural gas produced in Brazil. While some of its fields are equipped with permanent measuring equipment, some of its remote wells are currently using the mobile express surface well testing system. Brazil’s industry...

Case Study: GeoBalance® Service Helps Operator Save Big in Challenging Deepwater Environment

Automated managed pressure drilling system successfully drills ‘undrillable’ wells in 2,000 meters of water CHALLENGE – The operator elected to use managed pressure drilling to overcome these challenges. This project would also be the world’s first implementation of a MPD surface control system onto a MPD ready drill ship. The safe and successful implementation of Halliburton’s GeoBalance® MPD technology required an engineered approach working closely with...

Case Study: Record-Setting Lateral Completion Achieved with Obsidian® Plugs

Halliburton and Eclipse Resources set 124 frac plugs averaging 5.3 frac stages per day CHALLENGE – Setting and drilling out 100 + frac plugs in an extended-reach 18,544 ft lateral is no easy feat, so finding a reliable, field-proven completion solution was key. Eclipse Resources considered running a sleeve system for the extended lateral; however, Obsidian® plugs proved to be a more economical option, and past...

Case Study: Use of Remotely Operated Technology Saves 45 Hours Rig Time

Remotely operated barrier valve and bridge plug increase operational efficiency while eliminating a number of intervention runs CHALLENGE – Chevron wanted to hydraulically set a production packer and provide dual well barriers with minimal intervention methods. The completion design had a limitation where only low pressure could be applied against the fluid loss device, hence the requirement for a separate packer-setting solution. The typical completion method...

Case Study: Source Control Operations Achieve Success on Offshore Drilling Platform

Boots & Coots team controls fire and manages source control operations after offshore blowout CHALLENGE – During drilling operations on a platform, a kick occurred after encountering an unexpected abnormal pressure formation. While circulating out the kick, a leak developed on the blowout preventer (BOP) stack, which then ignited. The platform was safely evacuated without any injuries, but the fire eventually degraded the structural integrity of...

Case Study: RapidStage® system with AccessFrac® service shines in the Bakken

A minimum of 30% sustained production improvement in over 20 jobs performed CHALLENGE – Operators in the Bakken and Three Forks formations seek to increase compartmentalization in their wellbores by adding more isolated fracturing stages. The goal – access more productive reserves thereby improving well economics with the goal of lowering cost per BOE. At the same time, these operators strive to minimize completion time in...
