1. for rigging up smaller ID BOPs to a Drilling or Workover BOP Stack
The Tomcat Tool
for rigging up smaller ID BOPs to a Drilling or Workover BOP Stack

2. What does it do?
Crosses over large BOP to small bore for wireline, coil tubing, snubbing or pumping
Rig up and rig down time is minutes
Achieves full working pressure of the annular preventer

3. Benefits? Has a full working pressure primary seal
A full working pressure back up secondary mechanical flow barrier
Enhances safety for the crew and operation
Saves time and money

4. What is it?
Two (2) pieces: - shooting nipple - hold down flange

5. Initial rig up of Hold down Flange
Install the hold down flange with the stack with standard studs
Test flange with the stack (e.g., upper BOP)
Full bore for drilling operations

6. How does HPSN rig up?
When you need small bore BOPs install the HP Shooting Nipple (HPSN) to hold down flange
Installs with acme threads (12 turns at low torque)

7. How does it work?
Upward or downward forces are supported by the flange
Primary seal is annular element
Secondary seal is lip seal

8. Hold-down flange assembly
Forces absorbed by threads
Pressure is sealed by lip seal and ring gasket

9. What is it good for? WL work on drilling stacks
Coil tubing on drilling stacks
Snubbing operations
Pumping operations

10. What are the advantages?
Saves lots of time and costs
Operations are safer for personnel and rig
Reduces climbing to install conventional systems
System is properly pressure tested

11. Cost advantage?
Conventional method with a requires removal and reinstallation of bell nipple and a crossover = 10 hrs
Tomcat Tool = 1 hour
Savings 9 hours per run
At $1500/hr for rig time savings = $13,500 per run (before rental costs)

12. Testing Detail? 1) Install flange 2) Install bell nipple
3) Run test plug in wellhead
4) Run flange test plug
5) Pressure test whole system (which pressure tests cap and upper ring gasket seal)

13. Test integrity? Upper ring gasket is tested
Lip seal in annular cap is tested
Tomcat system is full rating of the annular BOP
Has secondary seal not provided in conventional system

14. Proto type test Upper ring gasket is tested
Test plug
Upper ring gasket is tested
Lip seal in annular cap is tested
Tomcat system is full rating of the annular BOP
Has secondary seal not provided in conventional system
Hold-down flange
10m test

15. Normal Operations Full working bore Thread is protected
Seal area is protected
Protector is removable

16. Design loads 11” 5m version
Thread 1130kip
Studs 2000kip
HPSN connections in body 2000kip tension or compression
HPSN body 2000kips tension 500kips compression
Burst 14,000 psi WP = 5,000 psi
Test pressure 10,000 psi
Lip seal WP = 5,000 Test 10,000 psi

17. Specifications SF according to AISC Mgf by API 6A PSL-3
H2S spec to NACE MR-01-75
Materials ASTM Rockwell C hardness
Welding according to AWA
All outlets flanges to API 6A PSL-3
Material traceability and accountability
Protected under USA Patent law (use and equipment.

18. Features Forces (up/down) are supported fully Two (2) flow barriers
Quick and efficient rig up and rig down
Tests the upper BOP section (not done normally)
Flange is full bore when not in use
BOP is fully functional (can close blind)

19. Risk Reduction Indonesian blowout during logging 2001
Cost of control $44m
Loss of one year of drilling

20. Wireline Blowout

21. Total Parts Required

22. R-BOP + Tomcat Tool Bell nipple is a R-BOP housing
If well is unstable run R-BOP assembly
Drill ahead at balance

23. R-BOP that will match up with HPSN system
Star Rotating Head
Rotating head system
WP = 1000 psi
Test 2000 psi
No lubrication system required

25. TomCat Tool Patented Process
