Hold 300psi on the string and slowly RIH the wash tool (40) to locate top of perforations indicated by pressure bleed off. We may now assume that the fluid enters into the perforations. Continue to RIH a further 2ft to place the wash tool (40) swab cups in perforations. Now we start washing. Start pumping to circulate out to the annulus between the wash tool (40) swab cups and increase rate to a maximum loss free rate aiming for a minimum 8.7bbl/min aiming for 12bbl/min.

  • the wash tool (40) of the BHA is built to Option 2 with 1.76ft between internal cups to ensure blank casing sections are straddled. At bottom of perforations continue to pump a string volume while stationary. Switch off pumps and - pull up to top of perforations and repeat the wash down pass while monitoring for a decrease in washing pressure. We now reach the bottom perforations. The washing procedure is now finished and we prepare for primer and cementing of the washed-out casing annulus. But first we must circulate out the washed-out debris from the tool annulus.
  • wash tool (40) into blank casing below perforated zone and verify wash tool (40) swab cups pressure integrity to 1,000psi and continue to pressure up to 3,000psi shearing out the second ball seat (42) 1.375” ball seat and regain circulation through the bottom of the wash tool (40).
  • Max allowable rp on the rotary unit is 50 - 80RPM.
  • Typical time to cut can be 2-5 minutes. Cutting time is calculated from when cutting pressure is reached. Variations in cutting time are not unusual.
  • Knives are now retracted into the pockets.
  • cutter tool (20) shall not be used for excessive circulation. If the spear tool (10) was not inserted in the original toolstring, now the spear tool (10) shall be inserted into the toolstring. The reason for not having inserted the spear tool (10) before now is twofold: Firstly, if the spear tool (10) is in the embodiment of a SPEARHEAD spear plug tool (10') it has drag blocks and thus cannot rotate with the cutter tool. Secondly, the activation ball , the fourth ball (22) for the cutter tool (20) may be larger than the bore of the SPEARHEAD spear plug tool (10'). P/U the spear tool (10) assembly and remove the Safety Clamp from the spear tool (10) Running Tool.
  • Step 1 Work the toolstring up and down
  • Step 2 Apply fluid pressure while pulling, max 1,885psi bar in 290psi steps (reduce max pull to 649klbs + block weight when applying 1 ,885psi, because the fluid pressure will create extra tension in DP)
  • Step 3 Keep pressure / tension for a while to allow for possible movement of the severed-off casing section, max 30 minutes. If still no free severed - off casing section, we still have the cutter tool (20) available in the well but cannot cut without laying out the spear tool (10). See below. If the severed-off casing section is free and possible to move, release the spear tool (10), because we will now lay out the cutter tool (20) and the wash tool (40) before pulling out the severed-off casing: Slack off to have 5klbs above free rotation weight (FRW). Release the spear tool (10). In case of using a spear plug tool (10'), still with 5klbs above the free rotation weight (FRW), start RH rotation at 15-20 RPM, in order to release spear plug tool (10').
  • spear plug tool (10') when spear plug tool (10) is free, pull the string slowly as you rotate another 10 turns. Then stop rotation gently as you continue pulling the string another 10-12 ft.
  • spear plug tool (10') If no indication that spear plug tool (10) has released after 20 turns, increase over pull in steps towards pick up weight. Once spear plug tool (10) releases pull the string slowly as you rotate another 10 turns. Then stop rotation gently as you continue pulling the string another 10-12 ft.
  • HWU Fastest pulling speed with weight of string is 1min per 15ft stroke which includes jack movement time
  • Circulation ports 1ft below top perf @ 8,028ft Total volume of Spacer pumped should be 205bbl (52bbl pumped into perforations).
