What happens is that at the correct depth the drillstring stops rotating, then drilling fluid is pumped through the mud motor so that the drill bit starts to turn just due to the force of the liquid.
Horizontal drilling can avoid salt domes, and reduceÂ pressure on equipment near fault lines.
Since curvature induces bending stress, it should be kept to a minimum so that the load is reduced.
The flat surface area of the water and the likelihood of human-made dams and walls might give us a false idea of the topography of an underground reservoir.
The number of offshoots will depend on the shape of the reservoir, so that maximum hydrocarbon reserves are reached.
This can occur where there are multiple bed dips or altitudes.
