Abstract

A system for remote monitoring of well operations. The system may include an alerts module positioned proximate a well, at least one well parameter sensor in communication with the alerts module, and a well operation control module in communication with the alerts module. The system may further include a remotely positioned well monitoring station in communication with the alerts module, and a user terminal in communication with the well monitoring station.

Claims

1. A system, comprising:

an alerts module positioned proximate a well and configured to monitor a well component;

a plurality of well parameter sensors in communication with the alerts module;

a well operation control module in communication with the alerts module;

an actuator coupled to the well component and in communication with the well operation control module;

a remotely positioned well monitoring station in communication with the alerts module; and

a user terminal in communication with and remote from the well monitoring station,

wherein sensed well parameters obtained by the plurality of sensors are locally processed by the alerts module to determine if a sensed well parameter is a predetermined parameter selected by a user for transmission, and the alerts module decides which sensed well parameters should be transmitted to the well monitoring station based on the determination,

wherein the remote user terminal modifies one or more sensed well parameters forwarded by the well monitoring station based on information desired by the user, and transmits the one or more modified sensed well parameters to the well monitoring station;

wherein the well monitoring station;

receives the determined sensed well parameters from the alerts module;

forwards sensed well parameters from the alerts module to the remote user terminal;

receives the one or more modified sensed well parameters from the remote user terminal; and

provides the received modified sensed well parameters to the well operation control module,

wherein one of the well operation control module and the well monitoring station is in bidirectional communication with the alerts module;

wherein the well operation control module outputs the received modified sensed well parameters to the actuator and, in response, the actuator physically adjusts the well component; and

wherein, in response to a communications medium between the alerts module and the well monitoring station being inoperative such that the well monitoring station is temporarily unable to communicate with the alerts module, the alerts module alerts local personnel of each alert and stores each alert until the communications medium between the alerts module and the well monitoring station is operative and, upon the communications medium becoming operative, the alerts module immediately transmits each of the stored alerts to the well monitoring station using the communications medium.

2. The system of claim 1, wherein the well operation control module and the well monitoring station are both in bidirectional communication with the alerts module.

3. The system of claim 1, wherein the well comprises a remote drilling platform and the well monitoring station is land based.

4. The system of claim 3, wherein the alerts module is positioned on the remote drilling platform and is in communication with the well monitoring station via a satellite communication system.

5. The system of claim 4, wherein the alerts module transmits the sensed well parameters to the well monitoring station via the satellite communication system, and wherein the well monitoring station compares the sensed well parameters to predetermined alert conditions.

6. The system of claim 5, wherein the alerts module stores sensed well parameters when the satellite communications system is not operational and reattempts transmission of the sensed well parameters when the satellite communications system becomes operational.

7. The system of claim 1, wherein the well monitoring station analyzes the received sensed well parameters, determines if an alert condition has occurred, and transmits alert information to the remote user terminal when an alert condition is determined.

8. The system of claim 1, wherein the remote user terminal transmits well control information to the well operation control module in response to alert information.

9. A computer program embodied on a non-transitory computer readable medium, wherein the computer program controls a method for remotely monitoring a well drilling process, comprising:

receiving and processing, by an alerts module that is located in a remotely positioned well and that is monitoring a well component, sensed well parameters to determine if a sensed well parameter is a predetermined parameter selected by a user for transmission;

deciding, by the alerts module, which sensed well parameters should be transmitted to a well monitoring station based on the determination;

receiving, by the well monitoring station, the determined sensed well parameters;

generating, by the well monitoring station, a comparison of the received sensed well parameters to predefined alert conditions for the well component;

determining, by the well monitoring station, when an alert condition exists for the well component based on the generated comparison;

transmitting, by the well monitoring station, an alert condition warning to a land based remote terminal when an alert condition is determined;

receiving, by the well monitoring station, a well operation parameter adjustment instruction from the land based remote terminal, wherein the well operation parameter adjustment instruction addresses the alert condition; and

transmitting the well operation parameter adjustment instruction to a well operation control module positioned at the remotely positioned well, wherein the well operation control module outputs the well operation parameter adjustment instruction to an actuator that is coupled to the well component and, in response, the actuator performs a physical well operation parameter adjustment on the well component that addresses the alert condition;

wherein in response to a communications medium between the alerts module and the land-based remote terminal being inoperative such that the alerts module is temporarily unable to communicate with the land based remote terminal, the alerts module alerts local personnel of each alert and stores the alert condition warning until the communications medium between the alerts module and the land-based remote terminal is operative and, upon the communications medium between the alerts module and the land based remote terminal becoming operative, the alerts module immediately transmits each stored alert condition warning to the land-based remote terminal using the communications medium.

10. A method which comprises:
