Case Study CTDirect Ultraslim LWD Array Resistivity service
CTDirect Ultraslim LWD Array Resistivity™ service unlocks geosteering and formation evaluation onshore.
CTDirect Ultraslim LWD Array Resistivity
Coiled tubing logging-while-drilling service
Overview
Optimizing formation evaluation and well placement
CTDirect Ultraslim LWD Array Resistivity™ coiled tubing logging-while-drilling service is a new and advanced ultraslimhole wave propagation resistivity measurement tool for formation evaluation and well placement. Specially designed for coiled tubing drilling applications, it enables the evaluation, development, and production of reservoirs while minimizing reservoir damage. With its built-in geosteering workflow, this innovative technology helps maximize reservoir contact while boosting production potential. Its robust design ensures reliable operation even in harsh drilling environments, including high-temperature conditions, delivering greater efficiency, cost savings, and improved drilling performance.
Applications
- Ultraslimhole drilling operations in 3⅝-in [9.21-cm] to 4¾-in [12.07-cm] wellbores
- Coiled tubing drilling, reentry, short-radius wells, relief wells
- Real-time quantitative formation evaluation
- Well placement
- Geosteering
- Underbalanced and overbalanced coiled tubing drilling operations
Benefits
- Improves reservoir management by enabling petrophysical evaluation of reservoirs being developed by coiled tubing that previously relied solely on gamma ray data
- Maximizes hydrocarbon recovery through enhanced well placement during coiled tubing drilling operations by integrating while-drilling formation evaluation measurements into a unique geosteering workflow
- Excels under harsh coiled tubing drilling environments, including high-temperature environments
- Enables precise trajectory control by transmitting while-drilling high-resolution resistivity measurements to the surface via e‑line telemetry for more informed real-time decisions
Features
- Combinable with CTDirect™ coiled tubing directional drilling system for real-time, while-drilling data transmission
- 2 MHz and 400 kHz phase-shift and attenuation borehole compensated measurements
- Unique model-compare-update technique
- Ultrahigh-speed data transmission through e-line telemetry
- High temperature rating up to 350 degF [175 degC]
CTDirect Ultraslim LWD Array Resistivity service enables petrophysical evaluation of reservoirs being developed by coiled tubing, which previously relied solely on gamma ray data.
