Title: 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
