Separate Production Metering From Each Formation When Integrating Taml-1 Well Construction Technology with Quantum Plt at The Novoportovskoye Field

Summary There are the remaining undeveloped hydrocarbon reserves at Novoportovskoye field occurring immediately under massive gas caps. To make field development economical in such geological settings, new technologies are required. This article describes the experience of constructing a multilateral well according to the new TAML Level 1 completion scheme, utilizing rock characteristics of the impermeable roof of the underlying bed and the dynamic Quantum PLT to arrange for separate production metering from each formation. Multilateral wells have been extensively drilled in the Novoportovskoye field in order to expand the drainage area. The dynamic production logging technology based on the use of quantum dot marker-reporters was chosen to arrange for separate production metering. The CAPEX and construction period have decreased by about 38%. The design enables separate production metering from each reservoir without stopping production. In addition, the costs associated with the regular interpretation of data obtained by analyzing the samples containing quantum-dot markers are offset by a reduction in operating costs for the pumping unit and service of well workover teams. The operator company has resolved to replicate the technology. However, the potential for this scale-up is limited by the requirements for the geological structure of the section.
