25
There are two types of standing valves; which one must you use with the RRT and CRT Tools?
The one with the Top No-Go is the one to be used.
26
Name the 11 main components of a CRT Setting Tool?
1. Mandrel 2. Retainer Ring 3. Torque Bushing 4. Shear Screws 5. Cylinder Lock Sleeve 6. Hydraulic Cylinder 7. Torque Sleeve 8. Connector Sleeve 9. Collet 10. Bottom Sub 11. Standing Valve Seat
27
In which position is the CRT Setting Tool released from the packer or setting adapter?
Position 2 is the Release position. The pressure pulled up the collet and the shear screws sheared.
28
When does the Hydraulic Setting Tool have advantage over the Mechanical Tool?
Hydraulic release - for easy release especially in deviated wells.
29
Name 3 benefits of the CRT Running Tool?
1. High Torque Capability: For reaming and drill down applications 2. High Tensile Rating: For carrying heavy Liner jobs. 3. Secondary Release feature: ¼ turn to the left plus Set-Down weight - for a backup release in case of hydraulic failure.
30
Explain the Secondary Release feature of the CRT Running Tool?
In case the Hydraulic release fails with the CRT
31
What is the function of the Optional Standing Valve Profile?
It is a Back Up in case of Ball Seat Failure. The standing valve is installed into it and will act like a secondary ball seat if the first one had failed.
32
List 4 characteristics of the Junk Bonnet?
Liner Top Debris barrier; Positive Latch; Internal Bypass; Secondary Shear Release
33
List 4 Benefits of the Junk Bonnet?
Prevents debris from entering the TBR; Remains engaged latched until retrieval; Provides pressure equalization/allows TBR pressure equalization; Ensures 100% release
34
What is the function of the positive Latch System of the Junk Bonnet?
Prevents premature release of the JBT- Junk Bonnet.
35
Name one feature that makes it easy to use the Junk Bonnet?
Easy disengagement on the rig floor to fill the TBR with fluid (Hi-Vis Gel).
36
Name the 3 main parts that make up the Junk Bonnet Latch System?
Top Nut; Lift Nut; Shear Sleeve
37
What is the function of the internal bypass of the Junk Bonnet?
The Internal Bypass is for pressure equalization across the TBR.
38
What is the function of the Secondary Shear Release ?
It is a secondary release feature that ensures a reliable release in case the spring does not compress enough to provide a primary release
39
List 4 characteristics of the Rotating Dog Assembly (RDA)?
It has rotating capabilities; Machined shoulders; Premium tool joint connections; Tensile rating equal to or greater than the liner running tool
40
What are the benefits of the Rotating Dog Assembly?
Allows rotation of the work string to transmit weight more efficiently
41
Name the listed parts of the Rotating Dog Assembly (RDA)?
Body; Thrust Bearings; Housing; Dogs; Dog Retainer; Bronze Bearing
42
What is the function of the Machined Shoulders in the RDA?
The machined shoulders are for optimum weight transfer.
43
What improvements were made to the RDA to make it more robust?
Maximized Tensile and Torsion capacity to match system limits.
44
What is the function of the Handling Sub?
To provide a crossover to the rig Drill Pipes.
45
What is the function of the Extension?
Provides a crossover of the Running Tool Assembly to the Handling Sub and drill string; Helps in spacing out the Packer Setting Dogs; Helps in the installation of the Junk Bonnet.
46
What is the function of the Spacer Sub?
Provides space out for a standard 15ft TBR.
47

53
Name these parts on the Retrievable Cement Bushing?
Top Adapter; Polypak; Body; V-Packing; Top Ring; Lug; Nose; Bottom Ring
54
What is the function of the Slick Joint?
The Slick Joint ensures the RCB stays in place and seals while RIH and during circulation.
55
What happens to the pressure across the RCB when it is retrieved?
When the Running String is retrieved the pressure across the RCB equalizes.
56
Where is the RCB located in the Liner Assembly?
The Bushing seats and locks into a profile machined in the Setting Adapter/Sleeve or Profile Sub or Liner Top Packer.
57
What is the function of the RCB?
Provides a fully retrievable seal between the Liner assembly and the workstring.
58
What is the function of the RBS-Rotational Ball?
It is a Ball Seat located in Running Tool Assembly that rotates and opens to a full ID once sheared.
59
What are the advantages of using a RBS rather than a BCLC?
Less time to land ball on seat in highly deviated/horizontal wells; Reduces shock effect to formation when sheared; Opens to full ID once sheared for PDP passage; Can be fully shear tested in workshop; Should never be used with RRT-HM Tool
60
What is the function of the Swab Cup Assembly?
The SWCA is used to hold pressure in applications where the high performance capabilities of a RCB is not required. Or, with RBS
61
What is the Plug Holder Pressure Equalizer Sub?
Component used in Dual Plug systems used for equalization when the system shears in two parts.
62
What does HEA stand for?
Hydraulic Extension Assembly; it is a hydraulic actuated tool used to set a liner top packer eliminating mechanical force requirement.
63
What are the advantages of using a RBS rather than a BCLC?
Less time to land ball on seat in highly deviated/horizontal wells; Reduces shock effect to formation when sheared; Opens to full ID once sheared for PDP passage; Can be fully shear tested in workshop; Should never be used with RRT-HM Tool
