Remarks
|
Correlated to Reeves Dual Laterolog-GR-Density-Neutron log dated 13-Jun-2004 (Run 1) |
R1
|
|
Tools were conveyed on drill pipe (TLC) due to sticking risk. |
R2
|
|
MDT Objectives were to record 54 pressure measurements between 3574m and 3006m MD in the Turrum reservoir. |
R3
|
|
60 pretests attempted: 47 good, 11 tight, 1 no seal, 1 unrecognisable (perhaps super-charged). All points are listed and |
R4
|
|
categorised in the Pretest Summary Tables below. |
R5
|
|
Pump-out module was used for 35 pretests to overcome plugging and super-charging effects. |
R6
|
|
Time limits were placed on pretests due to pipe sticking risk. Consequently, some pretests (3574.0m, 3561.0m, 3299.0m and |
R7
|
|
3207.0m) did not stabilise fully before retracting the probe. |
R8
|
|
No seal achieved at SLB depth 3530.0m (Reeves 3531.0m) due to open tool valve. |
R9
|
|
The depth difference (<0.5m) between the Reeves correlation log and SLB depth was not constant throughout the survey. Stop |
R10
|
|
depths were adjusted during the logging to allow for differences between the two logs. These differences (where they exist) |
R11
|
|
are shown in the log separators below, and remarked on the correlation passes displayed. |
R12
|
|
Note that depths shown in the Pretest Summary Table and Depth vs Pressure plots are Schlumberger depth. |
R13
|
|
Logger's casing depth and mud resistivities on header taken from Reeves log. |
R14
|
|
Mud data taken from Baroid Mud Report, measured at 20:00 on 12-Jun-2004. |
R15
|
|
Maximum recorded temperature taken from MDT resistivity cell temperature sensor at 3525m MD. |
