The following elements should be considered before any wire mesh operation: downforce gauge. Run the manometer to the specified operating depth. Run the flow control device below the wax point. Wax may clog the flow control device and should be eradicated before setting or discharging the flow control device. The depth of the bottom hole pressure instrument. The wire mesh should be tried before the instrument and the person.
If the operator does not intend to pull out the flow control equipment to log the bottom pressure. If the instrument falls into the well, the control device in the east and west sub prevents the instrument from coming out into the casing. Annulus fluid weight. a. If the tubing is clogged and the tubing pressure leaks to zero, the differential pressure may damage some parts of the tubing string.
The temperature. Flow control equipment should be placed at a satisfactory depth to avoid freezing through bottomhole nozzles or regulators. Bent tubing or deviated wells. wire mesh repairs are often affected by deviated Wells or severely bent tubing strings. If these factors can be predicted, the east and west subs should be installed at a higher than usual position on the tubing so that they can be repaired properly and securely.
In shallow Wells with high dip or deep Wells with slight dip, resistance will be evident. Special lubricants can deal with some conflicts. The total effect of the resistance will greatly constrain the jarring action of the wire mesh. In high dip Wells, great care should be taken when pulling down a pipe. An elastic assembly shall be used to ensure satisfactory and rapid disassembly of the casing and return to the tubing.
