Downhole kick detection based on power monitoring of shale shaker(s)

One or more non-transitory machine-readable media comprising program code executable by a processor to cause a device to perform operations comprising:

• performing a downhole operation in a borehole in a formation;
• capturing, during the downhole operation, downhole particles and drilling mud at a surface from the borehole into a screen of a shaker;
• monitoring input power that comprises at least one of voltage or current being supplied to the shaker during operation of the shaker;
• determining whether the input power exceeds a threshold as a result of change in a load on the shaker and change in a vibration pattern of the shaker;
• in response to determining that the input power exceeds the threshold as the result of change in the load on the shaker, determining that there is a kick condition in the borehole;
• and
• in response to determining that the input power exceeds the threshold as a result of the change in the vibration pattern of the shaker, continuing to monitor the input power without determining that there is a kick condition in the borehole.

A system comprising:

• a shaker comprising a shaker screen onto which downhole particles and fluid from a borehole are placed, the downhole particles a product of a downhole operation;
• at least a first motor which vibrates the shaker screen to separate the downhole particles from the fluid;
• a first sensor which monitors input power supplied to the at least the first motor;
• and
• a device to,
• monitor input power that comprises at least one of voltage or current being supplied to the shaker during operation of the shaker;
• determine whether the input power exceeds a threshold as a result of change in a load on the shaker and change in a vibration pattern of the shaker;
• in response to a determination that the input power exceeds the threshold as the result of change in the load on the shaker, determine that there is a kick condition in the borehole;
• and
• in response to determining that the input power exceeds the threshold as a result of the change in the vibration pattern of the shaker, continuing to monitor the input power without determining that there is a kick condition in the borehole.
