This article discusses the solution to the problem of active proppant removal from a hydraulic fracture into the wellbore. To reduce the amount of proppant removed not only at the stages of well development, but also during its operation, it is proposed to compact the proppant pack in the created hydraulic fracture with elastic hydraulic waves, which can be generated using a hydraulic spool vibrator. Well treatment according to the technology described in the article makes it possible to attract additional formation fluid to the working agent during hydraulic vibration treatment in field conditions. The use of this technology when testing an exploration well in an oil field has shown high efficiency in terms of increasing its oil production rate.
