Systems and methods for automated planning and/or control of a drilling operation are implemented to be based at least in part on automated prediction of well performance using an analytical well performance model. Substantially real-time determination of one or more drilling parameters and/or well trajectory parameters is based on measurements received from a drill tool together with the well performance model. The described techniques thus provide for automated, analytically determined well performance measures (e.g., well productivity and/or revenue) to a geosteering process. The well performance model accounts for variations of well trajectory both in inclination and in azimuth angle.

Geosteering based on automated well performance prediction

Predicting and visualizing drilling events. At least some of the example embodiments are methods including: receiving data indicative of location of a first wellbore; identifying an offset well, the offset well within a predetermined distance of the first wellbore, the identifying by the computer system based on the data indicative of location of the first wellbore; reading data associated with the offset well, the reading by the computer system; generating a value indicative of probability of occurrence of a drilling event based on the data associated with the offset well; plotting the value indicative of probability of occurrence of the drilling event associated with a direction relative to the first wellbore, the plotting on a display device coupled to the computer system; and then adjusting a drilling parameter of the first wellbore based on the value indicative of probability of occurrence of the at least one drilling event.

Displaying data associated with drilling a borehole. At least some of the illustrative embodiments are methods including: reading data associated with drilling of a first borehole, at least one datum of the data based on a controllable parameter; calculating an operational value related to drilling the first borehole, the calculating in real-time with reading the data and the operational value based on the data; determining a target value of the operational value, the determining in real-time with reading the data and the target value at least in part based on the data; displaying a first borehole trajectory on a display device; superimposing a first coordinate system over the first borehole trajectory on the display device, the superimposing proximate to a distal end of the first borehole trajectory; and plotting, within the first coordinate system, an indication of the operational value and an indication of the target value.

Planning and/or drilling wellbores. At least some of the various embodiments are methods including: receiving data indicative of position of a first wellbore; reading data indicative of position of an offset wellbore; reading data indicative of a fracture diameter for the offset wellbore; calculating a first positional uncertainty of the first wellbore; calculating a second positional uncertainly of the offset wellbore taking into account the data indicative of position and the data indicative of fracture diameter; and generating a value indicative of proximity of the positional uncertainties.
