The logging adapter will be
connected above the snubbing
adapter. This, in turn, will be locked
in the RCD sealing the annular
space through elastomers.

XOs VT 9 5/8” x O14 x ACME 4 ¾”
X-over of 9 5/8" Vam Top x Otis-14 and
another of O-14 x Acme 4 3/4" to enable
connection of the pressure control equipment
to the casing string.
O-14 x Acme 4 ¾”
9 5/8” Vam Top x Otis-14

5.

Pressure Control Equipment
HGT – Grease injection head.
VLL – Variable lubricator.
QTS- Rapid Test Sub
Triple Wireline Valve (BOP
WL)
X-overs 9 5/8” Vam Top O-14
Equipment that allows you to
maintain the pressure with the
train descending. Prohibition
against the WL.

6.

Lubricator
In this equipment, the seal is made through the
injection of high viscosity grease, through a
system of flow tubes, at a pressure at least
20% higher than the head pressure.
The injected grease penetrates between the
cable armatures providing seal even with the
cable in motion.

7.

Lifting Frame
It has a winch for train assembly and
eyelets to fix pulleys.
Equipment with "table / elevator" to wedge
/ suspend the coating and that allows the
assembly of the roll forming train, using Cplate. It has a working platform.

Proposed Sequence

9.

Proposed Sequence
The assembly of surface equipment
for MPD logging can be done in two
ways: In the first, the assembly is
done with the snubbing adapter
unseated and with the train on the
wedged coating, not allowing the
compensation of the set. In the
second, the roll forming train is
mounted with the snubbing adapter
already positioned and locked in the
RCD and, therefore, compensating.
For this first operation, it was decided
to do both methods. In the following
slides, the sequence of operations in
the order that was performed will be
shown.

Operation Performed

19.

Sequence performed
Lifting Frame (LF) Mobilization + Snubbing
Adapter
1.
Connected XO(O14 box x VT pin) in the 9 5/8" VT
casing pipe and 9 5/8+XO casing set + logging
adapter + snubing adapter in parallel to the
preparation of the first logging run.
2.

3.
Descended casing set 9 5/8+XO + logging
adapter + snubing adapter and connected two
joints 9 5/8" above this.
4.
Mobilized hydraulic unit to the platform and
connected another 9 5/8" joint to the assembly on
the MR while positioning the HPU.
5.
Moved LF to platform. Operation made difficult by
the size and weight of the equipment.

20.

Sequence performed
Lifting Frame Mobilization
Due to the weight, it had to be moved with a
crane, using a block.
It was not possible to lay it on the TFM due to its
dimensions (2.5 m wide), and it was necessary to
hold it with the crane throughout the operation.
Even though it was secured by the crane, the LF
was still subject to the vessel's movements, with
the risk of crashing into the facilities.
It was not possible to take the lift sub with lift at
first, because the crane was unable to take (with
the help of TFM) the LF to it.
It was necessary to hold the upper eye with
catline and stabilize the LF with catline to hoist it.

21.

Sequence performed
LF Positioning with 9 5/8" + XO Joint
1.
Positioned LF with 6 5/8" lift and 2 catlines assist
to stabilize it. The upper pulley was fixed before
the ascent.
2.

injector table and position the lower table
vertically.
3.
