Liner a string of pipe used to case open hole below existing casing, overlapping inside the upper string and held in place by a liner hanger packer. Main bore the main casing string from which subsequent directional drilling operations or openhole operations are initiated.
Lateral bores extend from the main bore to the desired target depth.
Migration a computational process applied to seismic data that returns reflection events to their origin in the subsurface. Moveout the difference in arrival times of reflected seismic data at different detectors. These lateral wellbores are connected back to a common main bore that extends to surface. Various levels of completion systems can be installed in a multilateral well to enable it to produce from several zones simultaneously. NMO Normal moveout offset the difference in arrival times of reflected seismic data at different detectors due to different source and detector separations.
