The Tomcat Tool

1
The Tomcat Tool

• for rigging up smaller IDBOPs 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
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
