Deep Well 801 – 121m of aggregate Potential Intervals.27 Nov 2022 16:36
I’m guessing the 801 Deep Well’s horizontal sidetrack will be deviated to drill through all four intervals (NET 121m) and not just one interval, the four intervals are between 4,535m to 4,812m and the sidetrack starts at 4,400m. Approx. 277m should take about 9 days to drill through plus whatever (hours/days) for the testing of each interval.
The potential of these four net-pay intervals combined is huge with one interval being 59m of potential net-pay, especially with the 802 Deep Well having already flowed oil at the shallower depths.

Deep Well 801 – 121m of aggregate Potential Intervals.
As previously announced our plan to bring Deep Well 801 into production was by drilling a side track of between 450 – 500 meters from a starting depth of 4,501 meters.
Having identified potential oil bearing (net-pay) intervals covering in aggregate 121 meters so far during the drilling of the side-track, we have decided to stop the side-track at a depth of 4,851 meters and, after running and cementing a 5-inch liner to the full depth of the side-track, to test the well.
Four potentially oil bearing intervals have been identified during drilling and supported by mud log data. The first of 6 meters between 4,535 and 4,541 meters; the second is of 20 meters between 4,554 and 4,694 meters; the third is of 59 meters meters between 4,635 and 4,694 and the fourth is of 36 meters between 4,812 and 4,848 meters.
The pressure in Well 801 remains high indicating good connectivity. As the side-track has been drilled using lower density drilling mud we expect the task of getting the well to flow to allow testing to commence should be easier than previously drilled deep wells.’’

‘’Work using horizontal drilling which has proved successful at several of the MJF shallow wells is planned for the New Year at existing Deep Wells A6 and 801 at a depth of approximately 4,400 meters.
The Company remains encouraged by the strong oil shows from Deep Well 802. Following an extensive cementing exercise we are now preparing to drill a side-track from a depth of 2,416 meters to a depth of 3,900 meters to target the first interval of interest from which the oil encountered to date has flowed. If successful and based on current timings we expect to test the well before the end of the year.’’
I wonder how many potential net-pay intervals there are between 2,416m and 4,848m on these two wells (801/ 802) and the A6 Deep Well to boot).
The thought of a 59m interval flowing commercial oil is mind boggling and I bet if commercial flow rates are the case the oil won’t be flowing in the hundreds of bopd from any of these two wells ;- ).
