... as low in the well as operationally allowable. But what happens if gas lift is applied along the bend or lateral? To help address this important question, we first leverage the vast knowledge gained from the inclined multiphase flow literature. The scientific knowledge base for up/down inclined...

... structural or lithological variations, the interval was planned for one run with a Rotary-Steerable-System (RSS) bottom hole assembly (BHA). During the horizontal drilling of a particular well, the BHA began to build inclination, and all attempts to correct trajectory resulted in incremental build. Initial...

This experimental study focused on understanding the cuttings transport mechanism in the annulus section with high-speed imaging technology. The movement of cuttings in the inclined annular section was captured with a high-speed camera at 2000...

... illustrates the risks of drilling wells without a good understanding of structure. If you are drilling with tight target thresholds, small dip changes combined with bed dip converging bit inclinationscan hurt you quickly; i.e. a 94 degree bed dip combined with a 92 degree bit inclination would bring you down...
