The Tomcat Tool

for rigging up smaller IDBOPs to a Drilling or Workover BOP Stack

what does it do
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
benefits
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
what is it
What is it?
  • Two (2) pieces:- shooting nipple - hold down flange
initial rig up of hold down flange
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
how does hpsn rig up
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)
how does it work
How does it work?
  • Upward or downward forces are supported by the flange
  • Primary seal is annular element
  • Secondary seal is lip seal
hold down flange assembly
Hold-down flange assembly
  • Forces absorbed by threads
  • Pressure is sealed by lip seal and ring gasket
what is it good for
What is it good for?
  • WL work on drilling stacks
  • Coil tubing on drilling stacks
  • Snubbing operations
  • Pumping operations
what are the advantages
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
cost advantage
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)
testing detail
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)

test integrity
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
proto type test
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

features
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)
risk reduction

r bop tomcat tool
R-BOP + Tomcat Tool
  • Bell nipple is a R-BOP housing
  • If well is unstable run R-BOP assembly
  • Drill ahead at balance
r bop that will match up with hpsn system
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
