Based on the Initial evaluations, rehabilitation options will be proposed. The entire well will have to pulled and the casing will have to be video Inspected. Common causes of reduced wall rapacity could be sanding, rupture of casing, mlneral build- U up, heavy encrustation, soman damage, semen clogging or mechanical failures of the pump, Deponding on the assessment, rehabilitation could Include brushing and bailing casing, replacing ruptured casing, adding an elon- gated nozzle to bull to reduce sand flow, chemical treatment, remachine the pump and or rewind.
