1. A method comprising:
identifying a production zone in a wellbore, the production zone flowing a fluid containing a particulate into the wellbore;
responsive to identifying the production zone in the wellbore, identifying that the production zone of the wellbore is an unconsolidated formation, wherein identifying that production zone of the wellbore is an unconsolidated formation comprises determining a rock strength of the unconsolidated formation;
responsive to identifying that the production zone is an unconsolidated formation, identifying that the production zone was hydraulically fractured and continued to produce the particulate during a flowback and cleanup operation;
responsive to identifying that the production zone was hydraulically fractured and continued to produce the particulate during the flowback and cleanup operation, identifying that the fluid further comprises a quantity of a salt, the salt precipitating within the wellbore to produce the particulate;
responsive to identifying that the production zone is an unconsolidated formation, identifying that the fluid comprises a quantity of water;
when, responsive to either identifying that the fluid further comprises the quantity of the salt or identifying that the fluid comprises the quantity of water, disposing a well test assembly in the wellbore, the well test assembly comprising:
a sensor configured to sense a condition of the wellbore and transmit a signal representing a value of the condition; and
a wellbore downhole shut-in device mechanically coupled to the sensor, the wellbore downhole shut-in device comprising:
a valve body comprising an inlet;
an inner sleeve coupled to an inner surface of the valve body, the inner sleeve movable from a closed position to an open position to allow a fluid flow from the wellbore through the inlet of the valve body and moveable from the open position to the closed position to stop the fluid flow through the inlet of the valve body;
an actuation mechanism coupled to the inner sleeve, the actuation mechanism operable to move the inner sleeve between the closed position and the open position;
a screen surrounding an outer surface of the valve body, the screen configured to filter the particulate from the fluid flow of the wellbore through the inlet of the valve body to reduce a quantity of the particulate in the inlet of the valve body below a predetermined threshold quantity; and
a plurality of end caps configured to couple the screen to the valve body and the actuation mechanism.
