Abstract
This invention contains a method focused on increasing the water saturation of the reservoir by injecting industrial water into the well via SPU, thus diluting the concentration of salts, such as halite (sodium chloride). When the oil passes through the gas lift mandrel, this dilution will allow a part of the BSW water to evaporate, however, the amount of water that will remain in the oil will be sufficient to keep the salts in solution, thus scale formation will not occur and therefore no loss of production will occur. One of the focus areas of the method of this invention are high-temperature and low-BSW production reservoir wells. The solution of this invention minimizes the frequency of well treatments, avoiding loss of production due to well stoppage. The technical advantages of the method are increased reliability for SPU, increased NPV of operations and increased safety due to the reduction of operations with participation of the stimulation vessel.
