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.

Methods and computing systems for processing and transforming collected data to improve drilling productivity

A method, apparatus and program product utilize an analytical reservoir simulator to perform inflow simulation for a node during nodal analysis in a multi-well petroleum production system. By doing so, time-lapse nodal analysis may be performed of a transient production system in a multi-well context, often taking into account production history and the transient behavior of a reservoir system. Moreover, in some instances, an interference effect from different wells in a multi-well production system may be considered, and in some instances nodal analysis may be performed simultaneously for multiple wells. Multi-layer nodal analysis may also be performed in some instances to account for the pressure loss in a wellbore between multiple layers.
