MAIN REQUIREMENTS OF GEOMECHANICS
TO INITIAL OPENING OF THE PRODUCTIVE FORMATION
casing must be opened fully (maximum on the entire length of the production interval along the column), but with considering the strength of the column
productive formations area should be opened as much as possible, and with possible a greater depth (exclude hit pieces of cement into the opened space of productive formation)
cement sheath should keep the integrity (cracks and destruction of the cement promote the flows of water from watered intervals and eventually lead to the flooding of the productive formation)
exclude formation of melted and other borders between opening area and productive formation (this prevents hydrodynamic connection of the well with the productive formation)
exclude connection (mixing) of productive and unproductive (watered and harmful) intervals (opening should take place only within the required production interval)
Based on the foregoing about malicious stress-strain states conditions in the near wellbore zone (initial factors), can be argued one more the following requirement:
is necessary unloading stress conditions in the near wellbore zone (in opening productive formation zone)
What kind of technology/method of opening casing, cement, and formation you know, that would satisfy all the requirements of Geomehanics ?
Comparative characteristics of the main initial opening methods clearly shows, that the most effective and meets all the required parameters of Geomechanics are HMSP (hydro-mechanical slotting perforation) and HSP (hydro-slotting perforation). The second, even more efficient because it uses abrasive sand. Wells which initially developed with using such effective opening methods (HMSP and HSP) continue "work" 10 -15 and more years.
