I have limited experience in Russia ( 6 yrs ) so can not generalize too much.
The fields that I saw were mismanaged. What do I mean? They made top of the structure maps. Drilled to find OWC and then would proceed to drill on a basic pattern 300m offset for example. They would put dots on a map and drill there. Where I worked THEY NEVER SIMULATED fields.
Their logs were OK to show pay but not for detailed petrophysics ( not modern analysis).
Their drilling departments worked autonomously and had set targets for metersto be drilled per year. THUS, they stuck wells where they probable should not have been. Just based on that map with the dots.
They would place wells on Injection when oil production woud go down, but the conscept of balancing injection patterns was not practiced. I saw committee meeting where this was discussed and that was it. No calcualtions. Just a committee decision of what to do.
To do this right you should build a model. Even a simple one would allow you to make decisions rationally amd perhaps better understand what is going on in the field. NO. They did not use this technology until they brought Western Companies in.
Today this is changing but then MAJORITY of fields were done this way.
Horizontal drilling. They invented it but they did not perfect it. Their old rigs would not be able to drill horizontals further than 200-300 m. To make matters worst, if you do not have a proper mud system and geosteering you are going to drill God knows what and the rate that well will get may be no better than a vertical well. Their mud pits were just holes in the ground so contamination of drilling mud was assured to screw the wells. Thus you would not see many hrizontals in their old fields. Besides Drilling dept. knew that it was safer to drill vertical and assure them better bonuses. Big Party for Christmas
For the Major Russian company I worked for WE brought in the drilling and reservoir expertise. They learned, now they are doing it themselves. To some extent. Hoever the top and middle management is ossified in most of these companies and is just waking up. They are greedy and do not want to pay western prices. END result is that they get good ol Russian results unless they openup. But once you spoil a field it take a hell of a lot of money to undo it IF YOU EVER can undo the damage.
Why was YUKOS so successful? Because they did simple things that had been done in the West for YEARS!!!
Do detailed OOIP, study production patterns in the field, estimate remaining production around a well, do NODAL , pull junk out of well, do short fracs to get through damage ( due to SUPER POOR drilling and workover fluid systems used by Russians in the past and present) AND BANGO SUPER WELL. This was something we learned at the University when I was getting my MS. After that everyone in Western Siberia wanted to do fracs and copy.
I am sure there were exception but something gives me the feeling that oil business was done in most of Russia as I describe above.
