To bore through; to pierce through with a pointed instrument; to make a hole or holes through by boring or piercing; to pierce or penetrate the surface of.
Pierced with a hole or holes, or with pores; having transparent dots resembling holes.
Making holes through the casing opposite producing formation to allow flow into the well.
slits in the paper made during the folding process - prevents wrinkles and allows air to escape.
(adj.) ( Iversen and Troels-Smith, 1950) A general adjective indicating the presence of holes, applied in palynology to holes less than 1µm in diameter and generally situated in the tectum. See also: punctum, scrobiculus. Peri- Synonym of panto-. Comment: Iversen and Troels-Smith (1950) used the term peri- (as for example, in pericolpate, periporate and pericolporate) in their classification of pollen types, but terms based on panto- are much more widely used. See also: pantoaperturate.
To make slits in the paper during folding, at the fold, to prevent wrinkles and allow air to escape. Books which perfect bind are perforated on the spine fold to aid in binding. to top
v: to pierce the casing wall and cement of a wellbore to provide holes through which formation fluids may enter or to provide holes in the casing so that materials may be introduced into the annulus between the casing and the wall of the borehole. Perforating is accomplished by lowering into the well a perforating gun, or perforator.
To perforate or die score in holes that allow one to cleanly remove a coupon or page from the piece with ease and not destroy the piece. If the perforation goes from top to bottom, that is a vertical. If from side to side, it is a horizontal perforation.
To create holes in the casing or liner to achieve efficient communication between the reservoir and the borehole.
make a hole into or between, as for ease of separation; "perforate the sheets of paper"
having a hole cut through; "pierced ears"; "a perforated eardrum"; "a punctured balloon"
A regular series of punched holes in a sheet which makes for easy tearing
Pierced by an opening(s).
Punching a series of holes or slits in a line in the paper, to weaken it so tearing will occur easily along that line. Also the making of slits in paper during folding, at the fold, to prevent wrinkles and to allow air to escape.
To perforate or a score line of holes that allow easy removal of a section of paper such as a coupon. If the perforation goes from top to bottom, that is a vertical perforation. If from side to side, it is a horizontal perforation.
Some paper folders have a perforating feature. Perforators punch small holes in paper that allow the paper to be torn easily. Bills and checks are typically perforated.
Piercing the casing and cement using shaped explosive charges to provide a flow path for formation fluids.
The process of creating holes in the casing to allow hydrocarbons to flow into the wellbore for production; usually consists of a hardened metal rod powered by an explosive charge.
To cut or punch a line of small holes around a portion of printed material to facilitate the tearing out of that section.
To pierce holes through well casing within an oil or gas-bearing formation by means of a perforating gun lowered down the hole and fired electrically from the surface. The perforations permit production from a formation which has been cased off.
to open holes through casing walls and cement into a formation so that fluids can flow into the borehole, or vice-versa.
To decorate an upper with a series of regularly spaced holes made either one after another by a perforation machine or all together by a perforating die.
Broken slotted cuts or rules to enable the paper to be torn in the correct place.
to punch a series or row of small holes or slots in a material to facilitate tearing.
Small holes put in the paper to make one area easy to tear from another.
tiny holes punched into a sheet, often used for tear-off cards.
Perforation occurs when a perforator wheel runs over the paper, creating several small holes. A checkbook is a good example of something that has been perforated.
Regular series of punched holes or slits along a sheet of paper or cardboard for easy tearing
To pierce the casing wall and cement of a wellbore to provide holes through which formation fluids may enter. Jet plasma charges are used to generate holes 0.5 – 1.0m in length.
