A method for controlling drilling direction of a bore hole assembly (BHA) while laterally drilling through a formation involves accessing, by a surface steerable system, recent TVD corrected logging history data from a bore hole estimator, iteratively determining, by the surface steerable system, a formation bed dip of the formation being laterally drilled through, repeating the steps of accessing the recent TVD corrected logging history data and iteratively determining the formation bed dip of the formation responsive to additional well information, determining, by the surface steerable system, a most probable statistical match of a well bore positions to predicated well bore positions based on the accessed recent TVD corrected logging history data, the determined formation bed dip and the additional well information and providing, by the surface steerable system, geosteering feedback responsive to the determined most probable statistical match.


An apparatus associated with a drilling rig includes a surface steerable system for controlling drilling direction of a bottom hole assembly (BHA). The surface steerable system is configured to receive drilling rig parameters from the BHA. A database stores historical data related to the drilling rig. The historical data relates to previously tracked operations of the drilling rig. The surface steerable system is further configured to perform a plurality of tracking functions with respect to the drilling rig parameters. The plurality of tracking functions cause the surface steerable system to track drilling rig parameters from sensors associated with the drilling rig, access the database of the historical data relating to previously tracked operations of the drilling rig and control operating functions of the drilling rig responsive to at least one of the drilling rig parameters from the sensors associated with the drilling rig and the historical data from the database.

A surface steerable system coupled to a drilling rig receives BHA information from a bottom hole assembly (BHA) located in a borehole. The BHA information corresponds to a first location of the BHA with respect to a target drilling path and geological formation drift information. The surface steerable system calculates a toolface vector to create a convergence path from the first location of the BHA to the target drilling path that accounts for geological formation drift defined by the geological formation drift information such that the BHA will converge with the target drilling path by drilling in accordance with the toolface vector. The surface steerable system causes at least one control parameter to be modified in order to alter a drilling direction of the BHA based on the calculated toolface vector and transmits the at least one control parameter to the drilling rig to target the BHA in accordance with the calculated toolface vector.


A method for locating planned markers within a log containing borehole data parses log data to locate an uncertainty region for a planned marker. A fingerprint match is located for the planned marker in the located uncertainty region. The located fingerprint match is saved. A determination is made if additional planned markers are present and returns to the step of parsing for a next planned marker if additional planned markers are present.

A system and apparatus for displaying toolface orientation data including a surface steerable system for controlling drilling direction of a bottom hole assembly (BHA). The surface steerable system configured to receive toolface orientation data from the BHA and generate display data responsive thereto. A circular chart display is generated responsive to the display data responsive to the display data from the surface steerable system, the circular chart display representing current and historical toolface orientation data. The current and historical toolface orientation data is represented as an arc indicator defined on the circular chart illustrating a range in degrees of the current and historical toolface orientations.


A system and method for surface steerable drilling are provided. In one example, the method includes monitoring operating parameters for drilling rig equipment and bottom hole assembly (BHA) equipment for a BHA, where the operating parameters control the drilling rig equipment and BHA equipment. The method includes receiving current inputs corresponding to performance data of the drilling rig equipment and BHA equipment during a drilling operation and determining that an amount of change between the current inputs and corresponding previously received inputs exceeds a defined threshold. The method further includes determining whether a modification to the operating parameters has occurred that would result in the amount of change exceeding the defined threshold and identifying that a problem exists in at least one of the drilling rig equipment and BA equipment if no modification has occurred to the operating parameters. The method includes performing a defined action if a problem exists.

A bicycle rear wheel quick release structure includes a rear hub (100), hub connector (200), quick release holder (300), quick release bolts (400) and fixing element (500). Flanked by an end plate and an opening, the rear hub receives a rear wheel transmission member (1). The end plate (110) has a central hole (111) and first positioning holes (112) surrounding the central hole which corresponds in position to the rear wheel transmission member centrally. Received in the rear hub (100) and coupled to rear wheel transmission member, the hub connector (200) has second positioning holes (220) and an axial post (210) with a fixing hole (211). The axial post is coaxial with the rear wheel transmission member and penetrates the central hole. Having a coupling hole (310), the quick release holder (300) is mounted on the end plate (110) and engaged with the quick release bolts (400) inserted into the communicated first and second positioning holes. The fixing element (500) penetrates the coupling hole and the fixing hole.


A bicycle pedal structure (1) capable of triggering auxiliary power includes a base (10), sleeve unit (20), crank shaft (30), pedal cranks (40) and treading force sensing unit (50). The sleeve unit (20) has first and second sleeves disposed in two openings of the base (10). The crank shaft (30) is fitted in the first and second sleeves and thus rotatably disposed in the base (10). The pedal cranks (40) are coupled to two ends of the crank shaft (30), extend in opposite directions, are substantially perpendicular to the crank shaft (30), and each have a pedal (41) for rotating the crank shaft (30) under a treading force. The treading force sensing unit (50) has piezoelectric plates (51A, 51, 5) disposed on at least the first and second sleeves and above the crank shaft (30). The bicycle pedal structure is mounted on a bicycle chassis and connected to a driving-controlling system to trigger the driving-controlling system to generate and supply digit modularized auxiliary power to the bicycle pedal structure (1).
