Assignee: SAUDI ARABIAN OIL COMPANY
Field: Measurement (Instruments)
Classification: CPC G  E | IPC E  G

Claim 8:
9. A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:
obtaining a measured present-day value of at least one parameter for each member of a set of at least one unvalidated layer arranged in order of increasing present-day depth in a subterranean sedimentary region of interest;
selecting a member of the set of unvalidated layers as a first current layer;
determining, by applying an iterative cycle of a decompaction modeling followed by geomechanical modeling, an estimated archaic value of the at least one parameter of the first current layer based, at least in part, on the measured present-day value of the at least one parameter of the first current layer,
wherein the geomechanical modeling comprises finite element modeling and wherein geomechanical modeling comprises temperature and chemical changes;

predicting a predicted present-day value of the at least one parameter of the first current layer using forward geomechanical modeling based, at least in part, on the estimated archaic value and the range of possible archaic values of the at least one parameter of the first current layer;
determining a validated archaic value of the at least one parameter of the first current layer based, at least in part on a difference between the predicted present-day value and the measured present-day value of the at least one parameter of the first current layer;
adding the first current layer to a set of validated layers;
removing the first current layer from the set of unvalidated layers;
determining a presence of a hydrocarbon reservoir based, at least in part, on the validated archaic value of the at least one parameter; and
determining a borehole trajectory through the subterranean region of interest based, at least in part, on the presence of the hydrocarbon reservoir.
