Record 1 2023-01-06

English

Subject field(s)
  • Equipment (Oil and Natural Gas Extraction)
  • Oil Drilling
  • Petroleum Technology - Maintenance
DEF

A device for cleaning mud and mud filter cake off of the wellbore wall when cementing casing in the hole to ensure good contact and bonding between the cement and the wellbore wall.

CONT

The scratcher is a simple device, consisting of a band of steel that fits around a joint of casing, and stiff wire fingers or cable loops sticking out in all directions around the band(360-degree coverage). A scratcher resembles a bottlebrush, but its diameter is greater than its height. Importantly, for scratchers to be effective, the casing must be moved. This movement may be reciprocal motion in and out of the wellbore, rotary motion, or both. In general, the more motion, the better the cement job will be.

Record 8 2004-09-07

English

Subject field(s)
  • Oil Drilling
DEF

A method of preparing a well for production in which no production casing or liner is set opposite the producing formation. Reservoir fluids flow unrestricted into the open wellbore.

CONT

A stage in the preparation of a well for production. After the well has been cased, cemented and serviced, each productive horizon is completed by making permanent contact between it and the well core, and installing tubing and the appropriate equipment for controlling fluid flow. Contrast with each horizon may be achieved directly, in the case of a barefoot completion, or by perforating casing. Completions may be single or multiple completions and separate tubings are run according to the number of productive zones, while a so-called tubingless completion may also be effected ...

Record 12 2001-08-14

English

Subject field(s)
  • Oil Drilling
DEF

To burn a hole through the casing with a shaped charge of high explosives instead of a gun that fires a projectile, as is used in bullet perforating.

OBS

The gun with loaded charges is lowered into the hole to the desired depth. Once detonated, the charges form short, penetrating jets of high-pressure gases that produce holes in the casing and cement and some distance into the formation. Formation fluids then flow into the wellbore through these holes, or perforations.

English

Subject field(s)
  • Oil Drilling
DEF

To create holes in casing and cement that is set through a productive formation. A common method of completing a well is to set casing through the oil-bearing formation and cement it at that depth. The casing is then perforated by a device lowered into the hole and fired to detonate high-powered jets or to shoot steel projectiles(bullets) through the casing and cement and into the pay zone. The formation fluids flow out of the reservoir through the perforations and into the wellbore.
