Summary. A well completion is a critical interface between the productive formation and the wellbore. An effective completion must maintain the mechanical integrity of the borehole without creating any significant restrictions on the flow capacity of the well. In this paper, a process is outlined to design optimal completions for horizontal wells by …

The maximum thickness of it reached 38 m, resulting in an overall drop in the elevation of the surrounding riverbed to 6 m. This means that the sand turning of the caisson has greatly disturbed the surrounding soil layers, especially for the bearing sand layer at the bottom of the well, where the thickness of disturbed layer was uneven.
