v: 1. to pull rods and tubing from a well at the same time-for example, when the pump is stuck. Tubing must be shipped over the rods a joint at a time, and the exposed sucker rod is then backed off and removed. 2. to move the drill stem, tubing, and other tools into or out of the hole with the well closed in. If the weight of the pipe is sufficient to overcome the upward force of well pressure, then the pipe can be shipped in. Compare snub.

a perforating gun where the charges are mounted on the strip. The strip is recovered after firing.

a recovery method, or less frequently, a wire installation method using pipe.

v: 1. to remove the drill stem from the hole while the blowout preventers are closed. 2. to pull the drill stem and the washover pipe out of the hole at the same time.

n: 1. the process of lowering the drill stem into the wellbore when the well is shut in on a kick and when the weight of the drill stem is sufficient to overcome the force of well pressure. 2. the process of putting tubing into a well under pressure.

v: shutting in and stripping in when well blowout .

the number of strokes that a mud pump makes in one minute. SPM times time times pumper chamber volume equals volume displaced. Can be compared to volume recovered.

n: congressional act that grants coastal states jurisdiction over a belt of submerged lands that extend seaward off the coastlines to a distance of 3 geographical miles (9 miles for Texas and Florida). Various state agencies are given authority under this act to enforce state environmental provisions for these lands.

n: light crude oil that contains sulfur compounds, often in the form of hydrogen sulfide. a capacity larger than 100,000 deadweight tons but less than 500,000 deadweight tons (45,360 deadweight tonnes) are called very large crude carriers. Those with a capacity over 500,000 deadweight tons are called ultralarge crude carriers.

a condition where the liquid is over saturated with incompatible ions or one ion concentration is above the saturation point. Usually a result of cooling a undersaturated fluid below the saturation point without a sufficient upset to start the precipitati

elevating the near wellbore pressure of a formation through leak-off of wellbore fluids during drilling, completion or workover.
