803 Deep Well drilling ahead to 3,950m?20 Jul 2024 13:57
The 803 Deep Wells unexpected 60m interval was not identified on seismic data as a target interval (similar to the 802 Deep Wells unexpected early interval at 3,900m). The abandoned 801 Deep Well that had identified oil bearing intervals (Three intervals have been perforated at Deep Well 801 and oil has flowed from each - even though the well didn't flow commercial quantities of oil why wasn't the 801 Deep Well included in the immediate drainage area (as a reservoir boundary?) and the A7 Deep Well has been and yet hasn't identified any oil down to 2,150 with an interval target at 4,000m, TD is set at 5,300m?. At the 802 Deep Well the salt layer is believed to be between depths of 3,580 meters and 3,860 meters. The 803 Deep Wells 60m interval is just above the salt layer and possibly sitting against the floor of the salt layer (ceiling). Because of this and the fact that this interval wasn't known I'm guessing it's a relatively small pocket of independent oil and the reservoir may contain only hundreds of thousands of barrels of oil/ 1 million barrels or so, the pressure this deep though should give a good flow rate hopefully similar/ better to the unexpected 802 Deep Wells 3,900m interval though this interval was below the salt layer and no doubt had a higher rate of pressure.
A thousand meter higher up in the shallows CASP drilled through 5 intervals (17m) between 200m: 143 Shallow Well - Five additional intervals; between 2,410 and 2,413 meters; between 2,370 and 2373 meters: between 2,328 and 2,331 meters; between 2,219 and 2122 meters; and between 2,193 and 2,198 meters (in total 17 meters) have been perforated, all in the Jurassic (The Company is pleased to report that Well 143 has flowed strongly since the New Year and continues to flow well).
''The average daily flow rates (barrels of oil per day ('bopd')) using different choke sizes have been as follows:
3 mm choke 520 bopd.
5 mm choke 675 bopd.
7 mm choke 815 bopd.
CASP have successful drilling through these 5 intervals and flowed them up to 815 bopd between 2,122m and 2,413m (291m) keeping the integrity of the well intact. My own thoughts are they will do the same with the 803 Deep Well and carry on drilling through the salt layer and onto their main target at 3,950m as the 803 Deep Well is their last exploration deep well to be drilled on BNG (the A7 Deep Well is unlikely to complete this year) and Yelemes immediate drainage vicinity Reserves will soon to be booked, which will depend on this well proving the deeper oil is connected to the 802 Deep Well, imo. We'll likely find out their intensions next week re drilling ahead or not to 3,950m.
