Abstract: A method includes determining a first geometric parameter of an elastic component based on a second geometric parameter of the elastic component, wherein the elastic component is part of a bottomhole assembly having a bit and an eccentering mechanism operating on the elastic component. The method also includes determining a length difference of the elastic component based on the first geometric parameter, the second geometric parameter, and a stiffness factor of the elastic component. The method also includes determining a borehole curvature based on a sum of a bit tilt angle and a force-based side-cutting angle, wherein the force-based side-cutting angle is based on the length difference of the elastic component. The method also includes determining a setting of the eccentering mechanism based on the borehole curvature.

Abstract: Systems and methods for determining a numerical age for new geological events within a new scheme by ordering relations between geological events within a new scheme and/or within a new scheme and a preexisting scheme into a preferred hierarchy, dynamically excluding lower relations in the preferred hierarchy that conflict with higher relations due to irreconcilable ages of the relations, and using the ordered relations remaining in the preferred hierarchy to determine a numerical age for the new geological events within the new scheme.

Abstract: A method and a system for modeling a three-dimensional geological structure. A method may comprise selecting input data from well measurement systems, seismic surveys or other sources, inputting the input data into an information handling system, building a quotient space, projecting constraints to the quotient space, constructing depth functions on the quotient space, trimming against a fault network, and producing a three-dimensional model of horizons. A system may comprise a downhole tool. The downhole tool may comprise at least one receiver and at least one transmitter. The system may further comprise a conveyance and an information handling system. The information handling system may be configured to select an input data, build a quotient space, project constraints to the quotient space, construct depth functions on the quotient space, trim against a fault network, and produce a three-dimensional model of a geological structure.

Abstract: Predicting casing wear, riser wear, and friction factors in drilling operations may be achieved with data-driven models that use discrete inversion techniques to updated casing wear models, riser wear models, and/or friction factor models. For example, a method may applying a linear inversion technique or a nonlinear inversion technique to one or more parameters of at least one of a casing wear model, a riser wear model, or a friction factor model using historical data from a previously drilled well as input data to produce at least one of an updated casing wear model, an updated riser wear model, or an updated friction factor model, respectively; and implementing the at least one of the updated casing wear model, the updated riser wear model, or the updated friction factor model when designing and/or performing a drilling operation.
Abstract: Tubular stretch correction for different operational conditions is applied to determine tubular wear volume. The tubular stretch correction is applied as a function of a stretch factor comprising a varying shift factor, axial load on the tubular string, pressure effects on the tubular string, buckling of the tubular string and/or temperature effects on the tubular string. Stretch factors are taken into account to determine the correct position of wear factors along the casing string, which are ultimately used to determine the casing wear volume.
