Abstract
A measurement while drilling system including a first module and a second module. The first module situated at a distal end of a drill string and including a downhole processor configured to determine that the drill string is one of on a drill plan and off the drill plan, and a downhole communication module communicatively coupled to the downhole processor to transmit signals. The second module situated at a proximal end of the drill string and including an uphole communication module configured to receive the signals. Where the downhole processor is configured to transmit non-compressed data if the drill string is off the drill plan and compressed data if the drill string is on the drill plan.

A measurement while drilling system, comprising:
- a first module situated at a distal end of a drill string and including:
- a downhole processor configured to determine that the drill string is one of on a drill plan and off the drill plan;
- and
- a downhole communication module communicatively coupled to the downhole processor to transmit signals;
- and
- a second module situated at a proximal end of the drill string and including an uphole communication module communicatively coupled to an uphole processor, wherein the uphole communication module is configured to receive the signals transmitted from the downhole communication module,
- wherein the downhole processor is configured to transmit downhole non-compressed data if the drill string is off the drill plan and downhole compressed data if the drill string is on the drill plan;
- and
- further wherein, when the uphole communication module receives the downhole compressed data, the uphole processor determines uphole non-compressed data from the downhole compressed data and the drill plan.
A measurement while drilling system, comprising:
- a first module situated at a distal end of a drill string and including:
- a downhole processor;
- and
- a downhole communication module communicatively coupled to the downhole processor and configured to transmit data from the downhole processor;
- and
- a second module situated at a proximal end of the drill string and including an uphole communication module having an uphole processor, wherein the uphole communication module is configured to receive the data transmitted by the downhole communication module,
- wherein the downhole processor is configured to determine a well segment of a drill plan in which the drill string is located based on an orientation of the drill string and to transmit compressed data that corresponds to the well segment;
- and
- further wherein the uphole processor receives the compressed data and determines non-compressed data from the compressed data, based on the drill plan.
A method of controlling well path trajectory comprising:
- determining, by a downhole processor, that the drill string is one of on a drill plan and off the drill plan;
- transmitting, by the downhole processor, downhole non-compressed data if the drill string is off the drill plan and downhole compressed data if the drill string is on the drill plan;
- and
- receiving, by an uphole processor, the downhole non-compressed data and the downhole compressed data;
- determining uphole non-compressed data from the downhole compressed data, based on the drill plan.
