first well and second well drilling method, two or more well drilling method, two or more parallel well drilling method and automatic second well drilling method with respect to a first well with an arrangement and distance previously determined
FIRST WELL AND SECOND WELL DRILLING METHOD, TWO OR MORE WELL DRILLING METHOD, TWO OR MORE PARAL WELL DRILLING METHOD AND A SECOND WELL DRIVING METHOD PREVIOUSLY DETERMINED Methods for drilling a first well and a second well are disclosed. The method includes measuring direction and inclination for at least one of the Bottom Hole Assemblies (BHA's) in the wells, generating a magnetic field in at least one of the BHA sets, and measuring the magnetic field in the wells. another set BHA. The method includes determining the geometric relationship of one BHA set relative to the other BHA set. The method further includes determining the position of a BHA set relative to terrestrial geology or geometry. The method further includes the automatic positioning of one well relative to the other well to maintain a predetermined geometric relationship between them.
