Abstract

Systems and methods for using high rate telemetry to improve drilling operations. A method may include performing drilling operations with a wired drill pipe (WDP) string in an oil and/or gas well. The drilling operations may include pumping drilling fluid to a mud motor of the WDP string through an internal passage of the WDP string and vertically moving the WDP string via a drawworks while controlling the drawworks to change speed of the WDP string based on downhole data received by wellsite surface equipment via electrical conductors integral to WDP of the WDP string. The received downhole data may include downhole pressure data that is generated downhole by a pressure sensor and is indicative of pressure of the drilling fluid in the internal passage.

1. A method comprising:
performing slide drilling operations with a wired drill pipe (WDP) string in an oil and/or gas well, wherein performing the slide drilling operations comprises:
imparting rotational oscillations to the WDP string by controlling a top drive based on at least a first portion of downhole data received by wellsite surface equipment via electrical conductors integral to WDP of the WDP string, wherein the at least first portion of the received downhole data comprises:
downhole rotational orientation data generated by a plurality of rotation sensors distributed axially along the WDP string, wherein the downhole rotational orientation data is indicative of rotational orientation of different sections of the WDP string and a toolface of a mud motor of the WDP string; and
downhole torque data generated by a plurality of torque sensors distributed axially along the WDP string, wherein the downhole torque data is indicative of torque transmitted through the different sections of the WDP string;

vertically moving the WDP string by controlling a drawworks based on at least a second portion of the received downhole data, wherein the at least second portion of the received downhole data comprises one or more of:
the downhole torque data; and
downhole axial load data generated by an axial load sensor of a bottom-hole assembly (BHA) of the WDP string, wherein the downhole axial load data is indicative of an axial load applied to a drill bit of the WDP string; and

pumping drilling fluid through an internal passage of the WDP string by controlling a plurality of mud pumps based on at least a third portion of the received downhole data;
the at least third portion of the received downhole data comprises downhole pressure data generated by a pressure sensor of the BHA; and
the downhole pressure data is indicative of pressure of the drilling fluid in the internal passage of the WDP string;
wherein controlling the plurality of mud pumps is based on torque at the drill bit (TAB), and wherein the TAB is determined based on the downhole pressure data.

2. The method of claim 1 wherein:
imparting rotational oscillations to the WDP string by controlling the top drive comprises maximizing rotational oscillations imparted to the WDP string while minimizing rotational oscillations of the mud motor toolface.

3. The method of claim 1 wherein:
performing the slide drilling operations further comprises receiving the downhole rotational orientation data and the downhole torque data at the wellsite surface equipment via the electrical conductors of the WDP string and repeater subs connected between joints of the WDP string; and
none of the repeater subs comprise any of the rotation sensors and the torque sensors.

4. The method of claim 1 wherein:
performing the slide drilling operations further comprises operating a processing device of the wellsite surface equipment to generate a mathematical model of a downhole system based at least partially on the downhole rotational orientation data and the downhole torque data; and
controlling the top drive to impart rotational oscillations to the WDP string is based on the downhole rotational orientation data and the generated mathematical model.

5. The method of claim 4 wherein the downhole system comprises the WDP string, a sidewall of a well being formed by the slide drilling operations, and wellbore fluid between the sidewall and the WDP string.

6. The method of claim 5 wherein the mathematical model describes properties at different axial locations along the WDP string.
