A method of predicting behavior of a drilling assembly includes: generating a mathematical representation of a geometry of each of a plurality of components of a drilling assembly, the plurality of components including a plurality of cutters and one or more additional components configured to at least one of: support the plurality of cutters and operably connect the plurality of cutters to the drill string, the one or more additional components including a drill bit crown; simulating one or more operating conditions incident on the drilling assembly representation, and simulating an interaction between the plurality of components and an earth formation; and predicting physical responses of the drilling assembly representation to the one or more conditions.

Modeling and simulation of complete drill strings

A method of controlling drill bit trajectory in a subterranean formation includes receiving drilling parameters for operating a specific bottomhole assembly (BHA), constructing, with a computer processor, a directional drill-ahead simulator including a computer model of the BHA and the subterranean formation, calculating axial motion and lateral motion of a drill bit connected to a bottom end of the BHA using formation parameters and drilling parameters, predicting bit walk of the drill bit by accounting for and calculating contact forces and frictional forces between the BHA and a wall of a borehole in the subterranean formation using the computer model of the BHA, and determining an adjusted drill bit trajectory to account for the predicted bit walk. The method includes determining adjusted drilling parameters for operating the BHA to substantially follow the adjusted drill bit trajectory and operating the BHA according to the adjusted drilling parameters.

Methods of controlling drill bit trajectory by predicting bit walk and wellbore spiraling

A method for predicting a path of a borehole that will be drilled in a rock formation by a bottomhole assembly (BHA) having a drill bit includes: constructing a model of the BHA; calculating confined compressive strength of the rock formation using an axial motion drill bit model that receives drilling parameter, drill bit design and lithology information; calculating lateral motion of the drill bit using a lateral motion drill bit model; calculating a ratio of lateral motion to axial motion using the lateral motion drill bit model; calculating an inclination angle and an azimuthal direction of the BHA using a BHA steering model that receives the ratio; and iterating the above steps by updating the BHA model to include extending the borehole an incremental distance in the direction of the inclination angle and the azimuthal direction and displacing the BHA the incremental distance in the extended borehole.

Directional drill ahead simulator: directional wellbore prediction using BHA and bit models

A method for predicting a change in lateral displacement with a change in axial displacement of a drill bit drilling in a formation rock includes: constructing a virtual representation of the drill bit and the formation rock, the drill bit having a gage pad configured to remove rock by wearing or crushing the rock during moving contact and a cutter configured to cut into the rock during moving contact with the rock; adjusting lateral penetration depth until rock reactive force equals a side force applied to the drill bit to provide an adjusted lateral penetration depth; removing formation rock to where the pad and the cutters contact the rock at the adjusted lateral penetration depth and to a selected axial displacement of the drill bit; moving the drill bit in a drilling direction to the end of the currently drilled borehole; and iterating the adjusting, the removing, and the moving.

Lateral motion drill bit model

A method for predicting an amount of axial motion of a drill bit having one or more cutters for drilling formation rock includes: receiving lithology data for the formation rock; receiving drilling parameters; calculating confined compressive strength (CCS) of the rock using the received information; calculating an area of cut into the formation rock by each of the one or more cutters; calculating an effective back rake of each of the one or more cutters; calculating a force applied to each of the one or more cutters using the CCS, the area of cut and the effective back rake of the one or more cutters, and by accounting for an orientation of each cutter with respect to a surface of the rock to be cut; and summing the calculated forces applied to each of the one or more cutters to calculate the weight on bit and torque on bit.

In one aspect, a seal apparatus for use with a mandrel is disclosed that in one non-limiting embodiment contains a seal housing disposed about the mandrel, wherein the seal housing is spaced apart from the mandrel to form a seal gap, a seal member disposed between the seal housing and the mandrel, wherein the seal member is bonded to the seal housing and the seal member is formed from a first material, and a seal support disposed between the seal housing and the mandrel, wherein the seal support is formed from a second material, wherein the second material is stiffer than the first material, and the seal support extends across the seal gap in response to an energizing force applied to the seal support.

Downhole sealing apparatus

An annularly shaped modular debris barrier can be mounted to an internal or an external member that are spaced apart to define an annular gap that could collect debris. The modules rotationally lock. Modules have circumferential segments that can be initially spaced apart to promote flexing that can occur when there is relative axial movement between the structures that define the annular gap. The gaps between segments are circumferentially offset as between adjacent segments to create a labyrinth through which the fluid can move in opposed direction while at the same time causing the debris to be retained. The segments stay in a flexed condition to exert a contract stress on the free ends thereof that touch the adjacent structure.

Modular annular debris barrier with rotationally locked segments

A method of generating a directional response of a drill bit based on one or more drilling parameters includes performing actual or simulated tests with a drill bit in a test material having a strength under different experimental drilling parameters and recording the results of the plurality of tests. A representation of an expected directional response of the drill bit is formed based on the results. Current drilling parameters are receiving current drilling parameters at a computing device and the directional response is generated based on the current drilling parameters by utilizing the representation.

Multi-parameter bit response model

An apparatus and method for delivering a liner wiper plug into a well bore on a workstring with a liner pipe, releasing the wiper plug from the workstring, and giving a positive indication of release of the wiper plug. A sleeve captures a collet to a latch ring until a plug is pumped down the workstring to cause a pressure buildup, which shears a shear screw, allowing the sleeve to shift, releasing the latch ring and the wiper plug from the workstring. A rupture disk is provided in the event of jamming of the apparatus, to allow pressurization above the wiper plug, shearing a weak link in the latch ring to release the wiper plug.
