Sentence examples for perforation casing from inspiring English sources

The methods and achievements in the paper provide theoretical supports for the popularization and application of shale stimulated reservoir volume and controlling the S-shape deformation failures of the horizontal multi-cluster perforation casing.

Based on the drilling and well completion data, microseismic surveillance data, theories of fracture mechanics, rock damage mechanics and rock failure criterion, this paper established a finite element model of the formation of effective stimulated reservoir volume, including clustering perforation casing for X-1 h shale gas horizontal well, to address the problems.

And, the state of this stress deficit, which would make clustering perforation casings of horizontal wells "hanging" in the formation to some extent, resulted in certain degree of deflection deformation radically and S-shape deformation axially.

Silicate scale is a very serious problem in the oil and gas industry; which forms in perforation holes, casing surface, tubing, and surface facilities.

The staged fracturing process of a horizontal well in Daqing Oilfield, China was simulated with the model, in which perforation, wellbore, cement casing, one pay zone, two barriers, micro-annulus fracture and transverse fracture are included.

And the water injection well use the casing perforation, wire wrapped screen and high quality screen.

The wellbore, cement casing, perforation, pay layer and the barriers are all included in the model.

The wellbore, cement casing, perforation, pay layer and barriers were included in the model.

In a series of closely monitored operations, the fluid is pumped down the borehole and through the perforations in the production casing under great pressure, powerful enough to enlarge and prop open existing tiny fissures in the shale.

In order to obtain maximum output, the well must be designed to have an open annulus between the wellbore and casing, with perforations near the top and bottom of the submerged heat exchanger, just below the water surface and at the hot aquifer at the bottom of the well.

The brine is penetrated through the perforations in the outer casing annulus and has the opposite flow direction (Feng 2012).
