Directional Drilling Control System And Methods
A method for forming a wellbore in an earth formation includes positioning a drill string in a wellbore; the drill string including a bottom hole assembly (BHA) that includes a steering unit, one or more sensors responsive to one or more formation properties, and one or more sensors responsive to the current orientation of the BHA in a wellbore. The method also includes receiving information from the BHA related to the formation properties and information related to a current orientation of the BHA in the wellbore and processing the information using computing device that is either a programmable optical computing device or a quantum computing device. The computing device calculates the position of formation features with respect to current wellbore position in real time and compare the current position to a prescribed path.

- 1. A system of drilling a wellbore in an earth formation, comprising:
a drill string including a bottom hole assemble (BHA) that includes a steering unit; a high speed computing device that is a quantum computing device; and a communication network coupling the BHA to the high speed computing device; wherein the quantum computing device, in operation, performs at least a 2-dimensional model inversion using data received from the BHA and calculates current wellbore position with respect to formation features using the data received from the BHA and compares that position to a prescribed path and provides information that causes the steering unit to perform a geosteering operation and change a course of the BHA during a drilling operation based on the comparison.
- 7. A method for forming a wellbore in an earth formation, comprising:
positioning a drill string in a wellbore; the drill string including a bottom hole assembly (BHA) that includes a steering unit, one or more sensors responsive to one or more formation properties, and one or more sensors responsive to the current orientation of the BHA in a wellbore; receiving information from the BHA related to the formation properties and information related to a current orientation of the BHA in the wellbore; performing at least a 2-dimensional model inversion of the information received from the BHA using a quantum computing device that utilizes qubits to perform calculations, the programmable optical computing device calculating the position of formation features with respect to current wellbore position; comparing the current position to a prescribed path; and causing the steering unit to perform a geosteering operation and change a course of the BHA during a drilling operation based on the comparison.
- 11. The method of claim 15, wherein the position information is based on a distance to a pay zone and the sensors include at least one formation evaluation sensor.
