A Closer Look At A CLR Second Bench Three Forks Well-- October 10, 2019

The Bakken is simply incredible. The Carson Peak/Morris wells are tracked here. This page will not be updated.

On this 10-well Morris / Carson Peak pad:

• four will be Middle Bakken wells
• three will be first bench Three Forks wells
• three will be second bench Three Forks wells
• took CLR only seven days to drill the second bench well
• did the entire well with no unplanned trips
• early indications suggest the second bench could be a better formation than the middle Bakken in this area
• second bench appears to be about the same thickness as the middle Bakken; about 40 feet thick
• measuring depths at two miles beneath the surface to the near half foot (to the nearest inch?)  
• the frack was a relatively small frack; only 29 stages; less than 8 million lbs sand
• must have come in under budget

A closer look at this well:

• 35109, 956, CLR, Morris 7-26H2, Oakdale, t4/19; cum 96K 8/19; 

File report: 

• this was a second bench, Three Forks well
• relatively small frack: only 29 stages; 7.7 million lbs sand
• field/prospect: Oakdale / Rocket
• spud date: August 26, 2018
• TD date: September 2, 2018
• seven days, spud to TD
• drilling:
• began operations using H&P rig 535 on August 26, 2018
• initial KOP of 10,982 feet MD was lowered to 10,995 feet MD
• drilling of the curve was completed with a single drilling assembly
• kicked off late on afternoon of August 29th (so about three days to drill the vertical)
• build rates came back strongly in the TF2
• Bakken shale collapse issues have been encountered in this region, and angles of intercept and shale exposure footage (for the Bakken shale members) have become important data (something we've discussed before on the blog)
• great description of what CLR engineers learned at the file report
• no shale well collapse issues were encountered on the trip out of the hole or the casing run
• the rig drilled out of the shoe late on the night of August 31 (it should take only 12 - 18 hours to build the curve, so there appears to be some down time between the completion of the KOP and beginning lateral operations)
• and get this: the well was completed in a single run. Amazing.
• gas readings: even with the gas buster, gas readings sometimes reached 4,000 to 5,000 units; gas averaged 2,000 units overall
• depths
• target thickness (Three Forks second bench): 41 feet 
• a nice description of the first bench at the file report; intercepted at 11,289 feet TVD
• the internal 1 shale top of the Three Forks was intercepted at 11,332 feet TVD
• the second bench was entered at 11,347 feet TVD: dolomite siltstone similar to the first bench
• ideal target felt to be 15.5 feet thick; to begin 6.5 feet belwo the internal 1 shale base, and extend to 22 feet below the same reference point
• two miles down and they are measuring this thing to within six (6) inches
• spacing unit: 2560 acres: sections 23/26/35-147-96; and, section 2-146-96
