<p>The invention relates to a method of extracting oil from a reservoir. The method comprises the following steps: drilling of a first well; mounting and cementing of well pipes in the first well; mounting of a Blow Out Preventer or Lubricator in the top of the well. At a distance from this well, a second well is drilled against a section of the first well such that the second well gets into operational contact with the first well. Hereafter well pipes are mounted and cemented in the second well; a Blow Out Preventer or Lubricator is mounted in the top of the second well; where after the drilling from the first or the second well is continued down into the reservoir.</p> |
