1
00:00:00,250 --> 00:00:02,697
Not every barrel comes from a new well

2
00:00:02,697 --> 00:00:04,951
Some are already there, behind pipe

3
00:00:04,951 --> 00:00:10,368
This is the story of how the Haima West team unlocked one of them, in the Marmul cluster

4
00:00:12,918 --> 00:00:14,855
Haima West is a mature asset

5
00:00:14,855 --> 00:00:19,214
The easy oil has long been produced, and decline is the default

6
00:00:19,214 --> 00:00:23,712
In fields like this, value is no longer created by drilling alone

7
00:00:23,712 --> 00:00:28,028
It is created by understanding the rock better than the day before

8
00:00:30,578 --> 00:00:37,655
Behind the casing, between the zones that were tested, sit intervals that were logged, and never produced

9
00:00:37,655 --> 00:00:41,496
Thin, easy to miss, and invisible on a completion diagram

10
00:00:41,496 --> 00:00:46,840
Behind-pipe potential only appears when somebody is willing to interrogate the data

11
00:00:49,390 --> 00:00:52,172
That is where the petrophysics starts

12
00:00:52,172 --> 00:01:00,895
R D L resistivity logs, tied back to the offset wells, depth matched, normalised and quality checked, track by track

13
00:01:00,895 --> 00:01:03,451
Shale volume, porosity, saturation

14
00:01:03,451 --> 00:01:06,660
Every cut-off challenged before it is accepted

15
00:01:09,210 --> 00:01:14,188
An Omani petrophysicist and her colleague worked that dataset line by line

16
00:01:14,188 --> 00:01:20,781
Long days at the desk, repeated correlations, small disagreements with each other, and no shortcut

17
00:01:20,781 --> 00:01:27,056
They recomputed the saturation, convinced themselves, and then set out to convince everybody else

18
00:01:29,606 --> 00:01:33,086
Because a petrophysical opinion is not a decision

19
00:01:33,086 --> 00:01:38,696
Production technology, geology and reservoir engineering reviewed the candidate

20
00:01:38,696 --> 00:01:42,176
The rock, the completion, the pressures, the risk

21
00:01:42,176 --> 00:01:46,684
Only when every discipline agreed did the opportunity become a plan

22
00:01:49,234 --> 00:01:50,380
Then the workover

23
00:01:50,380 --> 00:01:53,615
The interval identified on those logs was opened

24
00:01:53,615 --> 00:01:57,072
A zone that had never produced a barrel started to flow

25
00:01:59,622 --> 00:02:01,305
And production came back

26
00:02:01,305 --> 00:02:05,093
Incremental oil, from an interval that already existed

27
00:02:05,093 --> 00:02:11,156
New value without new drilling, and the field's life extended by one more barrel at a time

28
00:02:13,706 --> 00:02:19,127
Behind-pipe value is unlocked by data, by discipline, and by teamwork

29
00:02:19,127 --> 00:02:21,562
Haima West team, Marmul cluster

30
00:02:21,562 --> 00:02:22,648
This one is yours
