What is a Tubing Punch and Packoff Gaslift System?
Concept: Punch a hole in tubing, displace backside, set packoff assembly across punched hole with gaslift valve as part of packoff assembly, gaslift well through punched hole and gaslift valve.
The ChallengeTubing punch and packoff gaslift system as an “econo” gaslift system has long been done in shelf locations. Its application in a TLP environment has largely been untested, and poses a new set of challenges. This presentation will discuss the Ursa A9 tubing punch and packoff gaslift installation, what new technologies were employed, and the challenges and successes of the job. It’s application was the first for Shell at a TLP location in the Gulf of Mexico.
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 4
So, what’s different for TLPs versus Shelf locations?A few things to consider:• Equipment• Depth, Deviation• Cost• Annular gas volume*• Risks – HSE case*
What we did:• Identified well that could benefit from this operation (Ursa
A9) and designed job• Performed field testing• Put together HSE case• Implemented
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 5
Ursa TLP Overview• Set in 3,800 Feet of Water• Initial production 1999• 11 of the 24 Well Slots were Batch Set Across the Shallow Water Flow
Interval. • 11 DVA wells, completed between 1999 & 2004
Typical Ursa DVA well:– 18,000 - 29,000 ft MD– 5 ½” x 4 ½” tubing– Net feet 100-270ft, Perfs: 12-21 spf– Single or stacked zone sand control completions– Equipped with DHPG, SCSSV, Chem Inj Mandrel– No H2S tolerant tubing material currently installed– Gas lift mandrel in 1 well, installed in 2006*
• Crosby, Princess and Pastel Pink Subsea Tiebacks• Nameplate Capacity = 168 MBO/D, 40 MBW/D • and 540 MMCF/D• Peak Production: Total TLP (TG) 176 MBOPD, 326 MMSCFPD
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 6
Ursa A9 Well History• Well A-9 put on production in August-03 in the Aqua Terra-Cotta sand, fault block D. Is
the deepest measured depth well in the Gulf of Mexico at ~29,000’ MD• Peak rate from well was 20,677 bopd and 28.2 MMscfpd in Sept-03• Ramped up well wide open in LP system in June 2004• Well production uneventful until Feb-05 when it loaded up at a seemingly low water cut
(~ 17%). Prior to loadup, February well test was 6293 bopd and 12.6MMscfpd• Nitrogen bullhead intervention performed on the well in early March-05 to kick off the
well. Pumped two tubing volumes of nitrogen into the well twice without any success.• The well was finally brought back on production in April-05 after the BHP had built up
enough to facilitate flow with the help of a new unloading system (test separator pump)• Since then, well has loaded up several more times, requiring prolonged (1mo+) shut-ins
to reach the minimum observed SBHP to unload• Rig operations to pull the tubing and re-run with gas-lift mandrels were considered in
1Q-06 but ruled too risky. DRB ruled in favor of evaluating a “Tubing Punch” option to provide kick-off lift gas and minimize load-up time between shut-ins.
• Zone abandonment ruled out due to reserves left behind.• Well has a planned uphole recompletion to large reservoir.
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 7
Ursa A9 Well Unload (4/30/06 – 5/6/06)Wells loads up after shut ins. Unload in May 2006 – Took about 7 days to unload well to minimal backpressure (flare) before being able to flow well in production system (LP). Total gas flared ~20mmscf (~4mmscf/d). Total volume in system ~25,000 barrels fluid.
Unload to flare Put in LP production system
Shut in – well loads up
Watercut at start of unload ~45%. When well unloaded, watercut settles at ~20-25%
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 8
Ursa A9 Well Unload (7/23/06 – 8/2/06)Wells loads up after shut ins. Unload in July 2006 – Took about 11 days to unload well to minimal backpressure (flare) before being able to flow well in production system (LP). Total gas flared ~26mmscf (~2.5mmscf/d). Total volume in system ~33,000 barrels fluid.

Additional Information• Ran gradient survey. Fluid level below
SCSSV when well shut-in (~8505’ MD)• Watercut high during initial start up of well,
but drops over time as well unloads– Look at: Gaslift for kickoff versus Continuous
lift• Max injection gas pressure available on
platform ~1350psi (sales gas pressure). Need high pressure gas to lift if gaslift packoff set deeper than ~8100’ MD
• Will need to punch hole in 5.5” 23# 13Chrome tubing without damaging casing
• Install fairly big packoff in 5.5” tubing• Well angle builds up to ~63 degrees• If gaslift packoff set deep, will likely need
tractor to get to depth and operate setting tools
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 13
Job Design• Design for well lifecycle (reservoir pressures, watercuts, …) and
for good probability of successful installation• Operation will be done with electric line and slickline• Hole punch will be done with a punching tool rather than a
shaped charge, as this provides less risk of damaging the casing• If punch hole below SCSSV, only DHPG TEC line at risk• Packoff will be 2-7/8” x 3-1/2” with a 2-3/8” mandrel• 1” mandrel valve will be used for gas injection and can deliver
desired injection rates (varies over well life: ~ 2mmscf/d to 5mmscf/d)
• Nitrogen will be used for kickoff until Ursa gaslift case in place– Found nitrogen generation units that can deliver up to 10mmscf/d at
up to 95% N2 purity– Take platform uptime into account for economics on how often may
need to kickoff well

Pressure up on the tubing and punch a 0.75” hole in tubing at 5’ above the bottom packer.
Baker charge test of the 5 1/2" tubing. Shot resulted in entry hole of 0.75“.
Exit hole was also 0.75“.
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 16
HSE assessment
• Tubing Punch and Packoff gaslift option ALARP for TLP locations, under certain criteria. Keep in mind:– May not apply to sour wells– Need to define time/duration of equipment use in well,
especially if using less than 100% pure N2 (eg: from N2 generators)
– N2 for kickoff versus natural gas (natural gas may need separate HSE case for TLPs)
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 17

Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 18
Operational Difficulties and LearningsPunching hole in tubing:• Several attempts made to activate tubing punch tool on electronic firing
head not successful. Ended up using mechanical firing head to activate tubing punch tool.
Setting Packoff assembly and top packer:• Attempted to sting into the lower packer. After 2 attempts at running
speeds of 50 and 75ft/min, activated tractor. Switched power relay to tractor mode, activated tractor and pushed assembly into lower packer. Stung in.
• Attempted to switch relay power back to electric line mode in order to fire charge to set upper packer. Could not switch back from tractor mode or communicate with tractor. Tests showed there was voltage going to eline.
• Pulled out at rope socket, rigged up braided line and fished assembly out of well.
• Inspection BHA. Eline vendors crossover spring conducting the electricity between eline tool and tractor tool overheated, couldn't handle the amperage load when the tractor was activated.
• Re-ran in hole on eline with packoff assembly with top packer and tractor using tractor vendors crossover. Activated tractor to sting assembly into bottom packer, switched back to eline mode and set top packer.

~200psi - @ system pressure
Well appears to be loading up
Started injecting nitrogen
Well attempting to unload. BHP is coming up slightly, but temperature still increasing slightly
At 80% dump on the single WEMCo we had running. Cut back on N2 to manage produced water.
Unloading with nitrogen
Crosby compressor shut down. Increased pressure on FWKO. Had to increase backpressure on test separator in order to dump to FWKO.
Managing increased backpressure by increasing N2 rate until N2 ran out about 1 hour after compressor shut down
Crosby compressor back online. Trying to unload well to as min. backpressure as possible to flare. Will it unload??
Watercut ~ 60%. Well unloading for about 42 hours. Total fluid so far ~10,000barrels of fluid. If can keep well flowing/unloading for long enough at enough rate, will we see watercut reduction?
~50psi – going to flare- liquids going to system, gas to flare
Well Unload
Feb. 2 - 6, 2009 2009 Gas-Lift Workshop 20
As slugging reduced, temperature started coming back up. Watercut ~50%. The well stopped slugging (red line) and stabilized.
Rate ~5000bfpd from well @ ~50% watercut
Compressor problems. Increase in backpressure from ~40psi to ~300psi. Well barely flowing since then.
Watercut came down from 60% to 50%. Total fluids produced so far ~ 26,000 barrels of fluid. Well has been flowing for about 6 days.
