US 2003/0110794 A1 · Soil remediation well positioning in relation to curved obstructions

Abstract

A soil remediation system, such as an in situ thermal desorption system, may be used to treat contaminated soil in a treatment area with an arcuate obstruction in the treatment area. A pattern of wells may be positioned to avoid placing a well in a wall of the obstruction. The well pattern may be oriented based upon the center of the obstruction. A well of the well pattern may be placed at the center of the obstruction. Alternatively, the center of the obstruction may be positioned at a centroid of a unit of the well pattern, or at the midpoint of a side of a unit of the well pattern. The well pattern may be a regular pattern that is positioned so that the arcuate obstruction is placed within a large gap between adjacent orbitals (or rings) of the regular well pattern.

Dependent claims

A method of remediating contaminated soil in a geographic area that includes at least one obstruction, wherein at least a portion of the obstruction is curved, comprising:

identifying a center of the curved portion of the obstruction;
identifying a pattern for remediation wells in the geographic area;
locating the pattern relative to the center of the curved portion of the obstruction;
identifying a distance between remediation wells in the pattern;
determining a plurality of circles around the center, wherein each circle contacts a well location for a plurality of wells, or is located at a selected distance relative to the plurality of wells;
determining annular thicknesses between adjacent circles, the annular thicknesses being the radial distance from each circle around the center to the next circle around the center;
determining an obstruction spacing, the obstruction spacing being a thickness of the obstruction plus a distance from the obstruction;
and
using the annular thicknesses and the obstruction spacing to determine a location of the obstruction in the pattern.
