Sentence examples for lateral borehole from inspiring English sources

In this paper, we develop an analytical model to determine FIP, location of rock failure zones and initial fracture direction from the radial lateral borehole.

In addition, we compare the NAPL volumes determined by the PITTs with volumes estimated through geostatistical interpolation of aquifer sediment core data collected with a vertical frequency of 5 10 cm and a lateral borehole spacing of 0.15 m.

According to the state of art (Marbun et al. 2011), radial drilling is implemented through a special high pressure tube to form the water jet to penetrate and drill several lateral boreholes in one or several layers, which is an effective way to increase the drainage area and improve the oil recovery.

Open image in new window Fig. 3 BHA finite-element model for lateral considering well borehole contact.

Twenty-six days later, the borehole went through.

It would require, in addition to the increase in traffic, the repeated drilling of new boreholes and lateral tunnels that can run horizontally for several kilometres.

The rotation of a compression-buckling rotation drill string can increase the frictional force between the drill string and borehole wall, induce lateral vibration and whirl of the drill string, generate borehole wall instability and drill string damage, and even cause a drilling failure.

CT scan images of the tested specimens revealed two borehole failure modes, the lateral and the axial borehole failure mode depending on the stress combination.

Then, we perform a series of sensitivity analysis by examining different effects of in-situ stress regime, lateral orientation (the included angle between borehole axis and maximum horizontal in-situ stress), lateral length, and lateral diameter.

Under different confining pressures the lateral strain at the initiation point of borehole breakout is considerably lower in a larger size borehole (20 mm) compared to that in a smaller one (10 mm).

An example of optimising horizontal borehole locations in the longwall lateral direction is also given in this paper.
