Does EED account for tilted (with an angle) boreholes?
A. No, EED only allows for vertical boreholes. You can however use the middlepoint of the effective length of the borehole for an approximation. The “middlepoint” is at half of the depth of the borehole. In this case we consider that all boreholes are at least straight, when angled (not in a curve like in oil or deep geothermal). So if you draw a plan of the borehole field with the location on surface and extrapolate the relative position of the boreholes at final depth, the “middlepoint” is just in the middle from the top to the bottom point, seen either from top or from the side. For the distance of boreholes at this middlepoint, the boreholes in the upper half are closer to each other (I reckon only outward angles make a sense anyway), and in the lower half have more distance. So giving the middlepoint as “spacing”, you have the average distance. As written, this is not exact, but a good approximation. _______ Q. I am a registered user of the EED software.
