The Tornado Intercept Vehicle 1 (TIV 1) and Tornado Intercept Vehicle 2 (TIV 2) are vehicles used to film with an IMAX camera from very close to or within a tornado. They were designed by film director Sean Casey. Both TIVs have "intercepted" numerous tornadoes, including the June 12, 2005, Jayton, Texas tornado, the June 5, 2009, Goshen County ...
Dominator 1 was modified from a 2007 Chevrolet Tahoe that was used during the 2008 storm chasing season and debuted in the 2009 chase season. The modifications included adding bulletproof sheet metal and transparent Lexan armor to protect against flying debris near tornadoes, and an external roll cage and racing-style safety harnesses in case of a vehicle roll.

Rotary table (#20) rotates, along with its constituent parts, the kelly and kelly bushing, the drill string and the attached tools and bit. Shale shaker (#2) separates drill cuttings from the drilling fluid before it is pumped back down the wellbore. Stand (#16) is a section of 2 or 3 joints of drill pipe connected and stood upright in the ...
During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of drilling; to make detailed records (or well log) of the geologic formations penetrated by a borehole; to generate operations statistics and performance benchmarks such that ...
Rotary assemblies [2] are commonly used where formations are predictable and the rig economics are an issue. In such an assembly the weight of the drill collars gives the BHA the tendency to sag or flex to the low side of the hole, collar stiffness length and stabiliser diameter and placement are engineered as a means of controlling the flex of the BHA.
They are generally programmed by the measurement while drilling (MWD) engineer or directional driller who transmits commands using surface equipment (typically using either pressure fluctuations in the mud column or variations in the drill string rotation) which the tool responds to, and gradually steers into the desired direction.
[2] Before a tornado strikes an area, the wind has been known to die down and the air to become very still. [2] [dubious – discuss] A cloud of debris has sometimes marked the bottom of a tornado even when the funnel was not visible. Tornadoes typically occur along the trailing edge of a thunderstorm. The following is a summary of typical ...
