Get Production into the Pipeline• Reliable Results

Well 1- Reciprocated Well 2 – No Recip. Well 3 – Recip.

Planning is Critical!

• Customer and Halliburton pre-planning• Well Info

– Liner and casing Size– Mud System– Cementing system– Well profile– Threads, length, etc

• Running calculations– Well Plan – Torque and Drag– DFG – Surge and Swab– OptiCem – Cementing– Far-Pac – Job Parameters

Pre-Job Planning Activities

Running the Job

• Deploy the Liner• Circulate and Condition the Well• Mix and Pump Cement• Wash up at the Head• Release Dart and Engage SSR Wiper Plug• Land Plug• Set Hanger• Clean up the Well

Moffitt #1 Ream it to Bottom

• Anadarko Moffitt #1• Well information

– 9-5/8” 53.5# casing to 10,946 ft – 9.7 ppg water based mud – TOL Temperature 257°F– Bottom Hole Static Temperature 305 °F– TOL 10,689 ft– 7-5/8 39# Liner Shoe at 13,563 ft– Buoyed weight of 96,531 lbs– 10 degree / 100 ft build to 50 ° hole angle – Top of Cement at 12,050 ft

• Installation Issues– RIH at 1 min/stand– Stuck liner 160 ft off bottom– Over pull of 260,000 lbs required to un-stick– Stuck multiple times – Hole packed off – max pressure = 4,500 psi– Washed and reamed

• 26 hours• 8 bpm – 10.5 bpm pump rates• 8,500 – 14,500 ft-lbs torque• 35 to 80 RPM rotation

– Blocks fell uncontrolled for 12 ft– Washed at least one elastomer element off tool– Gas flaring throughout installation

Moffitt #1 Ream it to Bottom

• Installation Results– Pumped 16.2 ppg cement – circulation

throughout job– Plug shearing pressure of 2100 psi observed– Landed plug with 3.5 bbls over-displacement– Hanger set as designed– Pulled 300,000 lbs over to test hanger set– Setting tool released as designed– Observed 3 elastomers when releasing from

Hanger– Successfully tested to 4,200 psi differential– No problems encountered entering liner top

with bit
