$this->bbcode_second_pass_quote('Tanada', 'Y')up, it was a conventional field with water injected drive to keep the oil flowing. In the early 1990's they reworked it with multicompletion horizontal drilling and production soared from 1993-1997. They thought their golden goose was assured so they spent boucoup bucks upgrading the above ground facilities in the early 00's only to have production collapse like a ton of bricks. In the end they moved the oil production forward but did not produce any extra oil over original estimates.
Just teasing but Eagle Ford or not, if nobody ever drilled a field none of them would produce oil. I know you mean PB was already producing just at a slower rate and like Yibal it would have eventually given up its oil some time into the future.
Just a little story I picked up from a DD who worked on the Yidel project. Everybody was on bonuses for drilling rate, Co-man, DD, drill crew etc. Apparently the first few meters of the reservoir was made up of a hard slow drilling rock, which wasn't a real problem in the vertical wells, but for the horizontal wells it would have been a long hard drilling program. Below the hard stuff, was some softer, more easily drilled sand. As I said before everyone was on bonus so many people were prepared to a blind eye to drill a fast well, rather than what would have been more beneficial to longer life of the well.
Everyone in the drilling project was long gone before the production took its last fatal decline.
