vertical well
The solutions for a vertical well with a barrier and for a horizontal well in a finite productive stratum are found under certain assumptions concerning the properties of the mixture.
      
The steady axisymmetric flow of an incompressible fluid into a vertical well hydrodynamically perfectly drilled into a stratified inhomogeneous half-space consisting of three layers with different permeabilities is considered.
      
A mathematical model of the high-pressure gas flow in a gas-dynamic system consisting of a vertical well and two horizontal gas-saturated porous formations is considered.
      
An approximate one-dimensional theory of the process of transport of heavy solid rock particles by the flow of drilling mud in a vertical well is proposed.
      
A horizontal seepage well, consisting of an interconnected vertical well, galleries, chambers and small-diameter radiating bores, is used to acquire relatively clean water that has been filtered through natural alluvial deposits in a riverbed.
      
Unfortunately, it may produce inaccurate 3D simulations in deviated wells, even though the error remains below 1% for the axisymmetric (vertical) well.
      
For this highly-deviated well, readings corresponding to the conductive formation layer are about 30% smaller in magnitude than those in a vertical well.
      
A new approach is presented for the pressure calculation around a horizontal well or a partially penetrating vertical well in a finite height reservoir.
      
A model of wormhole growth was successfully tested in two sand production experiments simulating the growth of a wormhole from a perforation in a vertical well.
      
A vertical well is modelled by a narrow block, and the near-well region is modelled by another block with a hole.
      
A conventional kill sheet is good enough for a conventional large diameter vertical well with uniform well geometry.
      
Also referred to as slant or horizontal drilling, directional drilling begins onshore as a traditional vertical well.
      
Carbon dioxide injection started in January 2004 in vertical well 121/06-08 located 51m west of the observation well.
      
Considering both estimates, in this case the injected CO2 from a single vertical well should not migrate more than 25-50 km from the injection point.
      
Decrease of steam override effects near vertical well bores was also a goal of the well, one which so far has been attained.
      
Even when the two-phase kick mixture fills the build section of the well path, the SICP is considerably lower than that of a vertical well.
      
Figure 35 shows the gas saturation at 20 years, just after the completion of CO2 injection using a vertical well.
      
For this case it was also shown that a horizontal injection well was preferable to a vertical well.
      
Rod guides may be required in a vertical well too where buckling tendency is higher than tolerable.
      
This correlation was developed using data obtained from a 1500 ft vertical well.
