METHOD FOR DRILLING WITH IMPROVED FLUID COLLECTION PATTERN

摘要

A method for improving underground fluid collection and removal. The method includes drilling one well (20) with a vertical section and a horizontal section (40) having main bores and branches. All the branches are substantially in one horizontal plane except one branch for each main bore. That one branch (140) for each main bore is slope downward towards a common place, where a second vertical well is drilled for collecting fluid.
