BP/ARCO And Halliburton To Install First Integrated Multi-lateral System With One-size Casing Reduction
ANCHORAGE, Alaska - BP/ARCO Alaska Shared Services Drilling and Halliburton Energy Services announced today that they will install a new, integrated multi-lateral drilling and completion system in a North Slope of Alaska well. The system, which can turn an existing wellbore into one with multiple drainage laterals, will have full lateral liner connectivity, a hydraulically-isolated lateral junction and large-bore lateral re-entry access. It will be the world's first multi-lateral system to include these features with a reduction in the casing of only one size from the parent to the lateral wellbore.
Halliburton has drilled over 100 open-hole multi-lateral wells since 1993. During this time, the company surveyed oil and gas operators on a global basis to determine the current and future requirements for an integrated multi-lateral system. The company then initiated a joint development effort with BP/ARCO to design a solution that would address the present and future requirements.
Weatherford Inc. was chosen as the casing exit supplier for the system due to the company's extensive experience in providing milling and retrievable whipstocks in multi- lateral wells. The team brought together the highest level of expertise available in reservoir evaluation, drilling, cementing, fluids, pumping, completions, coiled tubing, milling, window cutting, and composite materials to develop an approach for existing and new wells that deploys state-of- the-art technology in a fully integrated system.
The three major features of an integrated multi-lateral system are connectivity, hydraulic isolation and access. "Connectivity" is the mechanical connection of the lateral wellbore to the parent wellbore. This provides stability at the juncture. "Isolation" is the external hydraulic isolation of the lateral wellbore from the parent wellbore through advanced cementing technology. This provides pressure integrity in both parent and lateral wellbores. "Access" is the availability of selective lateral re-entry in a proven method through the use of specialized tools.
Scott Sigurdson, BP/ARCO Shared Services Drilling Engineering Manager, said, "By using an integrated approach, we were able to expedite the development process and produce a solution that matches our needs."
After its initial installation in the BP/ARCO North Slope well, the technology will be deployed in the North Sea, Middle East and Gulf of Mexico as Halliburton's Multi- Lateral System 3000.
Halliburton Energy Services, a Halliburton Company organization, is one of the world's leading suppliers of energy products and services. Founded in 1919, the organization provides a broad range of services and products to the energy industry on a global basis.
