Non-intrusive wellbore diagnostics service provides decisive insight for optimal well intervention and integrityDownload PDF
The InnerVue™ WellSuite Diagnostics Service is a non-intrusive solution for wellbore diagnostic with Zero CO2 emission. The service can be used to detect top of cement, top of plug location or evaluate deposition in casing or tubing. In case of a stuck tool in the well, InnerVue can non- intrusively provide a depth of top of tool for efficient fishing operation. Data is collected by connecting directly to the wellhead or pipe system around the wellhead. The data collected is analyzed using proprietary software to profile debris or deposition, to detect changes in internal diameter, or to locate blockages in the wellbore or annuli.
Halliburton’s advanced technology employed in the InnerVue service uses a pressure wave (or pulse) generated by surface valve manipulation. The pulse travels inside the casing, tubing or annular space at the speed of sound and returns a reflected wave that corresponds to any features detected in the pipe bore or annulus, including deposition of wax, scale, hydrate, sand, salts, a stuck tool or even changes in the wellbore medium itself (based on density, viscosity, etc.). The pulse also reflects off top of cement or top of plug significantly reducing operating time and risk during P&A campaigns. A high accuracy transducer is utilized to measure the pressure variations, signals from the transducer are recorded at an ultra-high sampling rate. Once the data is collected, analyzed by the software and extrapolated into profiles, Halliburton’s team of experts provide diagnostic of the well condition. This includes reporting to facilitate decision-making and remediation plans — without sacrificing production uptime or throughput.
