Pressure Control During Wireline Operations
The pressure control employed during wireline operations is intended to contain pressure originating from the well bore. During open hole electric line operations, the pressure might be the result from a well kicking. During cased hole electric line, this is most likely the result of a well producing at high pressures. Pressure equipment must be rated to well over the expected well pressures. Normal ratings for wireline pressure equipment is 5,000, 10,000, and 15,000 pounds per square inch. Some wells are contained with 20,000 psi and 30,000 psi equipment is in development also

Famous quotes containing the words pressure, control and/or operations:
“The mother whose self-image is dependent on her children places on those children the responsibility for her own identity, and her involvement in the details of their lives can put great pressure on the children. A child suffers when everything he or she does is extremely important to a parent; this kind of over-involvement can turn even a small problem into a crisis.”
—Grace Baruch (20th century)
“Just as men must give up economic control when their wives share the responsibility for the family’s financial well-being, women must give up exclusive parental control when their husbands assume more responsibility for child care.”
—Augustus Y. Napier (20th century)
“It may seem strange that any road through such a wilderness should be passable, even in winter, when the snow is three or four feet deep, but at that season, wherever lumbering operations are actively carried on, teams are continually passing on the single track, and it becomes as smooth almost as a railway.”
—Henry David Thoreau (1817–1862)
