By Jerry Greenberg, contributing editor Weatherford’s newest tool in its Hostile Environment Logging (HEL) MWD system is its True Vibration Monitor (TVM) sensor, which is focused on providing pertinent downhole information to monitor bit and BHA vibration, primarily lateral and axial vibration, as well as rpm. Drilling is all about moving energy from the rig […]
By Jerry Greenberg, contributing editor Under development since 1988 and commercialized in 2003, the Schlumberger seismicVISION seismic-while-drilling service (SWD) enables operators to make seismic measurements during the drilling of the well. Operators can thus reduce uncertainty, optimize drilling decisions and improve safety. Previously, in most environments, this meant stopping the drilling process and running a […]
Compared with other sensor measurement tools such as wireline logging, logging-while-drilling (LWD) tools must stay downhole for extended periods of time and are subject to high vibration. While ratings of 25,000 psi and 350ºF may not be considered HPHT for some drilling environments, they are generally categorized as high pressure, high temperature for LWD tools, […]
The InSite Generation, being launched by Halliburton’s Sperry Drilling Services, is a new generation of LWD sensors and applications that provide deeper reading, higher resolution measurements with faster telemetry and greater reliability, said Blaine Comeaux, Sperry global marketing manager. Advanced miniaturization techniques have been used with the InSite Generation to reduce the number of components […]
By Jerry Greenberg, contributing editor Baker Hughes INTEQ’s MagTrak LWD tool provides a comprehensive range of magnetic resonance data for the operator, including formation porosity, bound and volume, free fluid volume, permeability, hydrocarbon detection and T1 and T2 distribution spectrums. Because the tool is based on magnetic resonance technology, it does not require a radioactive […]
For decades, the industry has been chasing the “look-ahead” dream – being able to see ahead of the bit as we drill. Whether that’s still an unfulfilled dream with current measurement-while-drilling (MWD), logging-while-drilling (LWD) and seismic-while-drilling (SWD) tools is up for debate. According to Schlumberger, its newest SWD tool, seismic-VISION, can send up to two […]
By Ivor Sinclair, Weatherford International Characterized by harsh, carbonate formations inducing high levels of stick-slip and vibration, drilling and completion work in Abu Dhabi presents a unique set of challenges. Nevertheless, the Revolution rotary steerable system (RSS) and Precision LWD have been used by a major operator in the region to successfully achieve complex drilling […]
By Jon Ruszka, Baker Hughes INTEQ Today, operators faced with discovering and developing hydrocarbon reserves are facing more, and more extreme, challenges. Every year, reservoirs are becoming more challenging to find and exploit. Similarly, the environments in which these reservoirs are located are getting increasingly hostile – either because they are in remote areas or […]
By Linda Hsieh, assistant managing editor In February 2008, when Exxon Neftegas Ltd (ENL) completed the world-record extended-reach well on Russia’s Sakhalin Island — drilled with Baker Hughes INTEQ’s AutoTrak G3.0 system — the well’s measured depth of 38,322 ft (11,680 m) stood as a testament to how far rotary steerables had come. Once an […]
