Abstract

Systems and methods for monitoring and/or operating a rig site system are provided. In accordance with one embodiment, a method for monitoring a rig site system may include obtaining sensor data at a rig site and transmitting pre-processed sensor data pertaining to the sensor data from the rig site over a network link to a monitoring site. The method may also include demodulating the pre-processed sensor data at the monitoring site to produce demodulated data. The method may also include analyzing the demodulated data at the monitoring site. The sensor data may comprise at least one of surface sensor data, MWD sensor data, or LWD sensor data, or any combination thereof.

Claims

1. A method for monitoring a rig site system, comprising:

obtaining sensor data at a rig site;

transmitting pre-processed sensor data pertaining to the sensor data from the rig site over a network link to a monitoring site;

demodulating the pre-processed sensor data at the monitoring site to produce demodulated data; and

analyzing the demodulated data at the monitoring site.

2. The method of claim 1, comprising pre-processing the sensor data at the rig site to produce the pre-processed sensor data.

3. The method of claim 1, comprising redundantly demodulating the pre-processed sensor data at the rig site.

4. The method of claim 1, wherein the sensor data comprises at least one of surface sensor data, MWD sensor data, or LWD sensor data.

5. The method of claim 1, comprising filtering the pre-processed sensor data at the monitoring site.

6. The method of claim 1, comprising performing a transform on the pre-processed sensor data at the monitoring site.

7. The method of claim 2, wherein pre-processing the data comprises compressing the pre-processed sensor data for transmission.

8. The method of claim 2, wherein pre-processing the data comprises encrypting the pre-processed sensor data for transmission.

9. The method of claim 1, comprising transmitting the adjusted system parameters to the rig site via the network link.

10. A rig site monitoring system, comprising:

a local data acquisition system configured to receive sensor data at a rig site, wherein the local data acquisition system comprises a local processor configured to pre-process sensor data to produce pre-processed sensor data;

a network link configured to transmit the pre-processed sensor data from the rig site to a monitoring site; and

an off-rig monitoring and control system located at the monitoring site, wherein the off-rig monitoring and control system comprises an off-rig processor configured to demodulate the pre-processed sensor data to produce demodulated data,

wherein the off-rig processor is further configured for analysis of the rig site based on the demodulated data.

11. The system of claim 10, wherein the local data acquisition system is configured to redundantly demodulate the pre-processed sensor data.
