The Tomcat Tool

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


What does it do l.jpg
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 l.jpg
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 l.jpg
What is it?

  • Two (2) pieces:- shooting nipple - hold down flange


Initial rig up of hold down flange l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
Hold-down flange assembly

  • Forces absorbed by threads

  • Pressure is sealed by lip seal and ring gasket


What is it good for l.jpg
What is it good for?

  • WL work on drilling stacks

  • Coil tubing on drilling stacks

  • Snubbing operations

  • Pumping operations


What are the advantages l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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 l.jpg
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

Hold-down flange

10m test


Normal operations l.jpg
Normal Operations

  • Full working bore

  • Thread is protected

  • Seal area is protected

  • Protector is removable


Design loads 11 5m version l.jpg
Design loads 11” 5m version

  • Thread 1130kip

  • Studs 2000kip

  • HPSN connections in body 2000kip tension or compression

  • HPSN body 2000kips tension500kips compression

  • Burst 14,000 psi WP = 5,000 psi

  • Test pressure 10,000 psi

  • Lip seal WP = 5,000 Test 10,000 psi


Specifications l.jpg
Specifications

  • SF according to AISC

  • Mgf by API 6A PSL-3

  • H2S spec to NACE MR-01-75

  • Materials ASTM 4130 22 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.


Features l.jpg
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 l.jpg
Risk Reduction

Indonesian blowout during logging 2001

Cost of control $44m

Loss of one year of drilling




R bop tomcat tool l.jpg
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 l.jpg
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
