Claim 11:
12. An apparatus comprising:
an analysis-while-drilling (AWD) control system utilized in conjunction with a well construction system during a well construction operation, wherein:
inputs for the AWD control system comprise:
intended configuration of a well being constructed by the well construction system during the well construction operation;
configuration of a drill string being used by the well construction system during the well construction operation;
signals from drilling parameter sensors; and
drilling equipment parameters; and

outputs from the AWD control system comprise real-time determination of:
depth and trajectory of the well;
bit depth;
number of drill string tubulars and/or stands in the well;
drill string volume, displacements, and weight;
drilling fluid tank volumes and tank selections;
drilling fluid loss and/or gain;
trip tank difference volume;
trip tank: accumulated volume;
total and/or per-section strokes and/or strokes-to-go of drilling fluid pumping system;
total stroke rate of drilling fluid pumping system;
drilling fluid pumping system liner capacities and efficiencies;
individual and total drilling fluid flow into the well;
annular drilling fluid velocity;
total and/or per-section drilling fluid volumes;
total minutes and/or minutes-to-go per section;
drilling fluid return flow;
bit runtime and revolutions;
weight-on-bit;
rate of penetration;
hook load; and
standpipe pressure.
