Following a competitive process, Halliburton has been onboarded by Petrobras for integrated drilling services across several offshore fields in Brazil.
Set to begin in 2025, the scope of the contract includes drilling services for development and exploration wells that will continue for a period of three years.
The contract enables Halliburton to provide iCruise intelligent rotary steerable system (RSS) to reduce well time and place wells accurately, and LOGIXTM automation and remote operations platform to improve well construction consistency and performance. The model also covers ultra-deep resistivity service, EarthStar, to position production boreholes and map reservoirs.
The iCruise RSS is known for its fast drilling and tripping time, besides quicker casing drillouts. This model brings predictability to an operator's schedule as it maintains precision of steering capabilities, while reliably reaching total depth, targetting longer wells.
LOGIX is a curation of subsurface and surface automation, digital twins, and remote operations; a one-stop solution for consistent well construction operations. Its wide-ranging advanced digital applications that synchronates design applications, rig control systems, remote operations, and downhole tools, enable critical engineering, operations insights, and automated operations.
The logging-while-drilling (LWD) technology that is EarthStar can interpret reservoir formations and fluid boundaries up to 225 feet (68 meters) around the wellbore. This lets operators position production boreholes accurately while mapping large volumes of the reservoir. Its 3D inversion feature gives subsurface insights in real-time, depicting a vivid image of the geology and fluids in place in three dimensions for better placement decisions.
Simplifying ultra-deep drilling
To address the technical limits of drilling fluids in offshore areas, Halliburton will deploy its BaraLogix real-time service to reduce lost time through advanced hydraulic software, surface measurement automation, and predictive analytics. BaraLogix operates alongside rig sensors to help specialists, drilling engineers, company men, field service representatives, and technical professionals. The tool identifies challenges such as downhole pressure or hole cleaning, and guides the personnel accordingly so as to reduce well construction time. It brings together advanced hydraulic software, surface measurement automation, and predictive analytics, ensuring data accuracy for fool-proof decision making.
The company will also utilise several other exclusive technologies such as Cerebro in-bit sensing and introduce innovative solutions such as the Reservoir Xaminer formation testing service. This service detects structural reservoir complexities and drives more informed decisions in drilling, completion, and production.
Cerebro in-bit sensors help improve drilling efficiency by enhancing bit design, bottom hole assembly and parameter selection. The tool provides in-bit measurements of vibration and rotation speed, forming the basis for advanced bit design, boosting drilling efficiency with a better rate of penetration and run length for a smooth and cost-effective drilling process.
"This contract demonstrates Halliburton’s strength in deep and ultra-deep offshore drilling and well construction," said Waldomiro Mendes, Halliburton's Senior Area Manager for Brazil.
Halliburton considers this its largest service contract with Petrobras, which significantly expands its drilling services footprint in the pre-salt and post-salt areas for both development and exploration wells.
