Remarks
|
Correlated to Reeves Dual Laterolog-GR-Density-Neutron log dated 24-Jul-2004. |
R1
|
|
MDT Objectives were to record pressure measurements between 2996.8m and 2535.5m MD (Turrum) and |
R3
|
|
between 1738.0m and 1450.5m MD (Marlin). |
R4
|
|
Tools were conveyed on drill pipe (TLC) due to sticking risk. |
R5
|
|
88 pretests attempted: 65 normal, 12 tight, 6 no seals, 5 unrecognisable. All points are listed and categorised in the Pretest |
R6
|
|
Summary Tables below. |
R7
|
|
Unrecognisable pretests are due to pressure communication through the mudcake to the borehole (fractures or uneven wall). |
R8
|
|
Super charged points have also been counted as unrecognisable. |
R9
|
|
Due to the high number of unrecognisable pretests between 2947.0m and 2942.0m, a repeat was performed at 2959.5m. |
R10
|
|
Both the pump and the second probe was used in the above mentioned interval to get a positive seal. |
R11
|
|
After sealing the formation was observed to be tight. |
R12
|
|
TD not tagged as per normal for TLC operation. |
R13
|
|
Pump was used 9 times during the logging operation. |
R14
|
|
Mud data taken from Baroid Mud Report, dated 24/07/2004 and from Reeves Dual Laterolog-GR-Density-Neutron log dated 24/07/204. |
R15
|
|
Maximum recorded temperature taken from MDT resistivity cell temperature sensor at 2938.0m MD. |
R16
|
|
Maximum deviation was 38.82 deg at 2043.39 m MD, taken from Schlumberger D&M survey dated 21/07/2004. |
