P2..........Yelemes Deep
The Yelemes Deep structure extends over 36 km2. To date two deep wells, 801 and 802 have been drilled to depths between 4,000 and 4,868 meters with a third deep well planned to spud before the year end.
At Deep Well 801 we are working with external geologists to determine the next course of action.
''Deep Well 801 was originally drilled to a depth of 5,050 meters reaching Total Depth in July 2015. As with the other deep wells drilled at BNG the well was blocked by a combination of excess drilling fluids and rocks from the potential reservoir.
For an extended period, the Company sought to remove the blockage with the use of chemicals and by periodically opening and closing the well as pressures grew. During that time oil flowed to the surface under its own pressure.
In May 2018 the Company announced it successfully completed a 350 meter side-track from a depth of 4,501 meters by-passing the blocked pipe. A 5-inch liner was run to the new bottom of the borehole at a total depth of 4,852 meters.
During the drilling of the side-track we encountered four potentially oil-bearing intervals. The first of 6 meters between 4,535 and 4,541 meters; the second is of 20 meters between 4,554 and 4,574 meters; the third is of 59 meters between 4,635 and 4,694 and the fourth is of 36 meters between 4,812 and 4,848 meters. Subsequently we perforated 75 meters of the intervals identified.''.
The 801 Deep Well has massive potential - why is the 803 Deep Well drilling to 3,950 meters and not targeting these very thick intervals deeper down as in the 801 Deep Well?
The 802 Deep Well has found commercially flowing oil at 4,000 meters so maybe they're drilling the 803 Deep Well to the same depth just to get some deep flowing oil under their belt from this interval(s) and will leave the deeper intervals in the A6 Deep Well until the Geo's and A6-7-802-3 well out comes.
Block 8
The Block 8 contract area extends over 2,823 km2 with three identified structures and production from two existing wells.
Drilling at Deep Well AKD-4 has reached its planned total depth of 3,922 meters and preparations are underway to test the well (Deep Well T-2D, has a planned total depth of 3,500 meters).
What's interesting is deep oil has been found/ flowing across all 4 structures between a depth of 1,500m, whether any of the structures are connected is still to be discovered, a common factor is deep oil has flowed commercially between approx. 4,000m and 4,400m across 3 of the 5 structures with the 2 on Block pending testing - if at all, is this where the structures could be connected?
