RE: Drilling procedure after huge oil find?
Hey Schill,
If you are coring the interval then you would either stop just above the reservoir or just barely into it and then circulate up a sample (and gas) to see if you hit it, then hoist up to change up your BHA to a coring assembly if you found your spot.
If you are just drilling the reservoir without core then you wouldnt stop to circulate up a sample ( could take up to an hour or two depending on your pump rate, hole size and depth) but rather would just keep drilling through it. Even if the reservoir was the last one before TD you would keep drilling so as to make some rat hole for the wireline logging tools and the completion tools- say 150 ft deeper than the bottom of your reservoir so the sensors on the top of your wireline tools can read into the bottom of the formation and give you a complete log. Even if you cored it you would still go back in with a drilling BHA to make rat hole and log it.
I imagine the WZR geo would love to core each reservoir interval but there could be limiting factors, I dont know.
Muley- what makes you think they could test 500 feet in a week? Just curious what numbers you are using for perforation intervals, shut in times, choke sizes, etc.? Is there anything behind that estimate or are you just throwing out random numbers? No offence intended, but you keep chattering on like you know something and for the life of me I cant see why.
