“…One of those advantages is that a horizontal well can have a great length of screen, thus can withdraw a significant amount of groundwater. In recent years, horizontal wells have gained increasing interests in the field of water resources management and environmental engineering, and a great deal of research can be found from Morgan (1992); Tarshish (1992); Cleveland (1994); Murdoch (1994); Falta (1995); Sawyer and Lieuallen-Dulam (1998); Zhan (1999); Zhan and Cao (2000); Streward and Jin (2001); Zhan et al (2001); Zhan (2002, 2003); Zhan and Zlotnik (2002); Chen et al (2003); Zhan and Park (2003), and others.…”

“…In the petroleum industry, horizontal wells improve oil recovery from petroleum reservoirs [ Joshi , 1988; Seines et al , 1994; Maurer , 1995; Penmatcha et al , 1997]. In aquifer remediation, horizontal or slanted wells are used to recover contaminated groundwater, nonaqueous phase liquids, and soil vapor from the subsurface [ Morgan , 1992; Environmental Protection Agency ( EPA ), 1994; Murdoch , 1994; Falta , 1995; Parmentier and Klemovich , 1996; Sawyer and Lieuallen‐Dulam , 1998; Zhan , 1999; Zhan and Cao , 2000]. These wells are commonly used for groundwater supply, drainage, and mine dewatering [ Hantush and Papadopulos , 1962].…”

[1] New semianalytical solutions for evaluation of the drawdown near horizontal and slanted wells with finite length screens in unconfined aquifers are presented. These fully three-dimensional solutions consider instantaneous drainage or delayed yield and aquifer anisotropy. As a basis, solution for the drawdown created by a point source in a uniform anisotropic unconfined aquifer is derived in Laplace domain. Using superposition, the point source solution is extended to the cases of the horizontal and slanted wells. The previous solutions for vertical wells can be described as a special case of the new solutions. Numerical Laplace inversion allows effective evaluation of the drawdown in real time. Examples illustrate the effects of well geometry and the aquifer parameters on drawdown. Results can be used to generate type curves from observations in piezometers and partially or fully penetrating observation wells. The proposed solutions and software are useful for the parameter identification, design of remediation systems, drainage, and mine dewatering.

“…Vertical flooding through horizontal wells, which is an emerging technology for groundwater remediation (Morgan, 1992), is another alternative for DNAPL removal. Based on gravity migration of mobilized DNAPL, downward flooding is expected to provide the most efficient displacement of residual DNAPL.…”

zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA A promising method of accelerating the removal of residual DNAPLs from aquifers involves the mobilization of trapped globules by alcohol flooding. This technology was originally developed in the petroleum industry for the recovery of residual oil after waterflooding. Alcohols can significantly reduce the interfacial tension between the residual DNAPLs and the aqueous phase, allowing for mobilization of trapped globules through pore constrictions. In addition, laboratory batch and column results show that certain alcohols preferentially partition into the DNAPL phase, swelling the residual DNAPL globules considerably and at the same time reducing their density significantly. The swollen DNAPL globules become a relatively continuous phase during flooding, making them much easier to displace than disconnected residuals. Density reduction makes the mobilized DNAPL easier to control, and reduces the potential for further downward migration into uncontaminated portions of the aquifer. Laboratory column results confirm that residual trichloroethylene and tetrachloroethylene globules can be effectively removed from glass bead packings at low upflow gradients using preferentially DNAPL-soluble alcohols.zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA Water Environ.
