n: a device that measures and indicates the amount of pulling force (tension) being put on pipe, a tape measure, etc. In tank strapping, the strapping crew attaches a tension gauge to the measuring tape they use to determine a tanks circumference. Knowing how much tension to apply to the tape is essential to accurate measurement because the same amount of tension must be applied to the tape each time they make a measurement.

n: a packer that is held in its set position by upstrain, or upward pull.

a packer set by pulling and holding tension in the tubing.

n: a device on a retrievable or drillable packer that allows the packer to be set with an upward pull (tension);it is often used when not enough pipe weight is available to set the packer by applying downward force (compression).

n: a compliant offshore drilling platform used to drill development wells. The platform, which resembles a semisubmersible drilling rig, is attached to the seafloor with tensioned steel tubes. The buoyancy of the platform applies tension to the tubes. See platform rig.

n: a system of devices installed on a floating offshore drilling rig to maintain a constant tension on the riser pipe, despite any vertical motion made by the rig. The guidelines must also be tensioned, so a separate tensioner system is provided for them.

n pi: severed minerals acquired for a certain time and, generally, as long thereafter as production continues.

n: a point to which oil is transported through pipelines. It usually includes a tank farm and may include tanker-loading facilities.
