If you read WHI's below view they think the well will be drilled to the initial target depth of 4,300m not the 'original' 5,300m TD, which leads me to think they might have forsaken drilling the deeper intervals in the 802 Deep Well to drill later i.e. drilling the potential 4 deeper intervals when they drill the 803 Deep Well - not risking the 700+ bopd discovery.

Caspian Sunrise announced that Deep Well 802 drilling the Deep Yelemes structure has struck oil unexpectedly (at 3,900m) above the targeted formation (expected at 4,300m). The well is now being sidetracked to a depth of 4,100m with a further 100m to be drilled to reach that depth. Caspian Sunrise has further announced that the well has flowed for three days at rates fluctuating from 700-900 b/d on an open hole basis.
The company indicated that once the well is completed (cased and perforated), they believe there is potential for the well to flow at a higher rate.
WHI View: Deep Well 802 has not yet been cased and it is drilling in a deep and over-pressured environment (beneath the Kungurian salt). We believe that the immediate priority of the company will be to drill the well to its targeted depth and then case the well, which involves cementing steel production tubing into the well. Thereafter, we would expect the company to test the well and to evaluate the unexpected oil discovery.''
Hence they've started drilling the 803 Deep Wells shallower reservoir to help prove up the reservoirs size and possibly drill the deeper intervals to boot.
It's looking more likely they have stopped drilling at the 4,300m initial target depth and moved on to the 803 Deep Well. imo.
