Sentence examples for a well trajectory from inspiring English sources

To achieve a wellbore trajectory control, one must use the underground real-time control or ground that can be remoted by a well trajectory control tool.

In this paper we describe a fully coupled solution approach for a well model that allows for a flexible well trajectory and screened interval within a structured hexahedral computational grid.

From this 'forward modeling', the compressive σ tmax as well as tensile stresses σ tmin and their orientations (θmaxmodel /θminmodel) are determined for a given well trajectory in an arbitrary stress field (see Chapter 4.2).

This can be the result of lower tangential compressive stress due to the well trajectory, a changed stress regime or higher rock strength in the Malm reservoir.

Since the distribution of fracture orientation identified from the image log depends on the angle (d°) between the fracture plane and the well trajectory, a bias correction for the fracture density, called 'Terzaghi correction', is applied (Terzaghi 1965).

Numerical modeling of the ground was carried out to better estimate and quantify the stresses, strains, and resulting deformation in the ground to determine the stress distribution in the ground and along the well trajectory within a pillar in the layout of a longwall mining area.

The restriction-style and frictional-style FCDs can improve conformance and delay breakthrough (as might occur due to a fracture, well trajectories that bring segments of the lateral close to gas cap/aquifer, etc). of unwanted water/gas/steam depending on the goals of their installation.

Underground information transmission is an important way of well trajectory remote control and manual intervention of trajectory automatic control.

Hence, the execution time of algorithms should be taken into account in addition to their ability to find the optimum well trajectory in a reproducible manner.

Open image in new window Fig. 1 Calculation of the length for a deviated section of the well trajectory after Atashnezhad et al. (2014) describes the terms used to define the different angles and components of the wellbore trajectory.

In order to apply an ACO algorithm to the well trajectory design cases evaluated, it was necessary to modify the decision space.
