Geological and engineering operations (GEO) developed directly in the field with no scientific and research organizations involved largely contribute to technical advancements in the oil and gas sector. However, as wise men of the old used to say: one can always find something bad where everything seems to be too good.

Following this thought I looked through the contents of papers dedicated to currently developed GEO and realized that some of the GEO aspects indeed require improvement. This pertains to additional perforation and re-perforation of target formations since repeated perforation proved to be ineffective (from the economic standpoint this method failed to provide the expected revenue to the field administration). One can't help but wonder: why did it happen despite the fact that perforation efforts in the wells have been going on for many years and so to say “accumulated” vast experience? So, what is the problem? Why no positive results have been achieved so far?
