An extreme-performance polymer-locked wireline cable overcomes the conveyance challenges in tortuous wellbores, enabling the acquisition of high-quality production logging data in extended-reach drilling (ERD) wells. The use of this technology enabled an operator in the UAE to successfully evaluate the downhole production and reservoir properties in four extended-reach wells drilled from an artificial island. Production logging data acquisition using conventional wireline cables is challenging in such wells because of extreme cable tensions. This paper presents a case study about a novel approach of combining an extreme-performance polymer-locked cable and high force tractors to successfully convey production logging tools in an extended-reach well, where previous attempts with two conventional wireline cable types had failed. The new approach is based on analyzing the drag forces acting on the cable in the wellbore and modeling the tortuosity of the wells for determining optimal cable and tractor properties to minimize these effects. Based on this in-depth analysis, high-strength, torque-balanced, polymer-locked coaxial cable and high-force tractors with large wheels are selected for the job. With meticulous risk management and establishing a core team of key personnel, including field operations, the operator, and the product manufacturing center, this new technology is successfully deployed. Production logging tools are successfully conveyed to the maximum depth of 27,800 ft, and safely retrieved from the well. Excellent flowing and shut-in log data are recorded in a single descent, making it possible to accurately quantify zonal contributions from this horizontal lateral for the first time. Good tension profile with new cable shows the value of torque-balanced cables in high-tortuosity well profiles. The success of the job created confidence in conducting safer, more efficient intervention in maximum reservoir contact development wells. It demonstrates the value gained by deploying advanced high-strength polymer-locked coaxial cables in combination with high-force tractors.
