Note these faces belong to an intersection of the cutter and rock discretized faces involved in the interaction. Each face has a normal (N) and velocity (V) vector...

... efficiency and reduces implementation errors. The consequences of an unplanned intersection with an existing well can range from financial loss to a catastrophic blow-out and loss of life. The process of well collision avoidance involves rules that determine the allowable well separation, the management...

... to locate the blowing wellbore when drilling a relief well. If no magnetic material is present in the openhole section of the blowing well, the last set casing shoe is the deepest possible intersection point. A deeper intersection point will increase the hydrostatic head, increase the frictional pressure...

Conversely, the method is found to be severely restrictive for the optimal positioning of deeper sections of a well where the magnitude of outcomes from the intersection of two wells is not as great.
