Abstract: Fluid data collected while drilling a wellbore in a drilling operation that includes a first well trajectory is received. A first productivity metric for a next section of the wellbore on a continued trajectory of the first well section trajectory is determined, based at least in part on the fluid data. A second well section trajectory for the next section of the wellbore different from the continued trajectory of the first well section trajectory is determined. A second productivity metric for the second well trajectory is determined. The drilling operation is adjusted if the first productivity index differs from the second productivity index by more than a threshold amount.

Abstract: To control well drilling, information relating to a trajectory of a well is received, and fluid flow in the well is simulated according to the received information. Simulating the fluid production comprises simulating production flow assurance that seeks to reduce occurrence of mixtures of different types of fluids that reduce production of a target fluid. In response to results of the simulating, a further trajectory for further drilling of the well is identified.
