Tech Unit - 7800 ACE Umbrella Plug

Field Operating Procedures using Push Tool (7801-169-A-001) and Blasting Cap Actuator (7801-169-A-011):

1.0 Tools Required

1.1. small screwdriver or hex key wrench set (depends on type of set screw used)

1.2. set of small pipe wrenches or chain vise grips

2.0 Assembly of Push Tool to ACE Umbrella Plug and Running Sleeve

2.1. Remove the ACE Umbrella Plug from the shipping tube. Verify the plug specifications listed on the Plug QC Sheet match the specifications required.

2.2. Remove nylon nut and PVC protection tube from Vent Valve atop ACE Plug Running Sleeve.

2.3. Slide the Lower Linking Sleeve of Push Tool all the way up on the Upper linking Sleeve exposing the fingers of the Collet. The bottom of the Linking Sleeve should be adjacent to the base cut of the Collet fingers; this verifies the proper placement of the piston inside the Push Tool.

2.4. Slide the Collet over the end of the Vent Valve and over the profile atop the ACE Umbrella Plug
(Figure 1). The fingers of the Collet should slide over the raised diameter of the profile and the leading edge shoulders inside the collet.

2.5. Slide the Lower Linking Sleeve down to the ACE Umbrella Plug Setting Sleeve. Rotate the Lower Linking Sleeve to engage the thread in the Plug Setting Sleeve. Continue turning until Lower Linking Sleeve is completely installed into ACE Umbrella Plug Setting Sleeve.

2.6. Secure ACE Umbrella Plug Setting Sleeve by installing a Set Screw into retaining groove of Lower
Linking Sleeve (Figure 2).

 

3.0 Attachment of ACE Plug and Push Tool String to Wireline for Installation of Detonator
NOTE: These procedures are written and provided as a guideline to assembly. They are not intended to replace standard oil and /or wireline company operational practices or safety procedures. Where a difference exists with such practice or procedures, standard company procedures should be followed.

3.1. Inspect all threads on setting sleeve and Double Box Window Sub (item 2). Verify make-up and compatibility with the Wireline Company electrical contact sub (item 1).

3.2. Attach the wireline tool string (weight bars, CCL, electrical contact sub for fluid exposed connection) to the wireline cablehead.

3.3. Make electrical checks required to verify proper working of the wireline tool string (CCL, electrical continuity, etc.)

3.4. Install or activate safety mechanisms required for handling and attaching explosives (safety key, grounding switch, grounding clamps, warning signs, etc.).

3.5. Using suitable downhole wire, establish an electrical connection to the conductor on the electrical contact sub. The wire should be long enough to extend thru the Double Box Window Sub. Insulate the electrical connection for operation in an exposed fluid environment, (e.g., rubber boot, electrical tape, etc.). Use nylon string or boot sleeve as necessary.

3.6. Make up the Double Box Window Sub to the wireline tool string. Pull the end of the attached wire thru the side window of the sub.

3.7. Remove the Detonator Retainer (item 5) from the interior of the Tension Bolt (DO NOT remove the large external nut adjacent to the thread of the Top Sub of the Tension Bolt Actuator Assembly). Place the wires and the appropriate fluid exposed detonator into the Detonator Retainer (from the threaded end) and install the Detonator (item 3) into the ID of the Tension Bolt until it bottoms out. Secure into place with the Detonator Retainer. An appropriate detonator would be an Austin Powder Oilstar A-96L or equivalent.

3.8. Pull the wire leads from the Detonator thru the bottom end of the Double Box Window Sub and out of the side window. Thread the Top Sub of the Tension Bolt Actuator Assembly (item 4) into the Window Sub.

3.9. Cut the Detonator leads to length and make an electrical connection from one lead to the wire connection established in step 3.5 above. This connection must be appropriately sealed for exposure to well fluid. Secure the other Detonator lead to the ground screw in the Double Box Window Crossover Sub. Place excess wire back into interior of the sub and secure.


3.10. The Blasting Cap Actuator is now armed and ready to run into the well.

 

  

 

4.0 Field Operating Procedure


4.1. Shut-in well 48 hours prior to starting plugback operations. KEEP THE WELL PRESSURE STATIC UNTIL YOU HAVE COMPLETED THE PLUG BACK PROJECT AND THE PLUG IS TESTED.

4.2. Perform an initial inspection of the well when first arriving at the well site. Record wellhead pressure and time. Pressure up the lubricator to well head pressure prior to opening the swab valve. Equalization of lubricator pressure and wellhead pressure prior to opening valve is required before each run. If the well has a full column of liquid to the surface, it also requires bleed-off of pressure increase caused by displacement when going inhole and replacement of the fluid when coming out of the hole.

4.3. Make a full length (same as dump bailer string) gage run, preferably with a thermometer or other temperature recording device. Record the BHT. Locate and note fluid level if possible. Note any tight spots. Run CCL across plug interval and determine if sufficient markers are present for accurate depth control via CCL.

4.4. Verify dimensional data from ACE Umbrella Plug QC Sheet corresponds to well parameters (QC sheet attached to plug shipping tube). Note dimensions for slip placement, basket location, and bottom of the plug.

4.5. Make up ACE Umbrella Plug running assembly with a CCL. An optional Bow Spring Centralizer is available to attach to the bottom of the plug for use in high angle wells and/or re-entry into smaller ID (e.g., isolation packer, liner top).

4.5.1. NOTE: The ACE Umbrella running leave has a heavy wall segment approximately 2-1/2” long immediately below the threaded end. Place wrenches only on this area when making up tool string. Do not clamp on the thin wall tube below the heavy wall segment.

4.5.2. Run the ACE Umbrella Plug in the hole. Once at desired depth, carefully tie in with casing collars. Locate the ACE Umbrella Plug below the setting depth and slowly pull up to the desired setting depth. If the setting depth is not critical, it is recommended that the bottom set of slips be set 1 foot into a perforated interval or 1 foot below a casing collar connection.

4.5.3. NOTE: The bottom end of the ACE Umbrella Plug is positively deployed one foot out the end of the setting sleeve when set. This must be added to the setting depth to place the basket at the desired depth.

4.5.4. Fire detonator to initiate Push Tool and release ACE Umbrella Plug at desired setting depth. Wait 1 minute and pull off bottom at <30 fpm, monitor the weight indicator for excessive drag.

4.6. Make up dump bailer to place 1-2’ of bridging material on the spring steel basket prior to placement of cement or resin. Additional bridging material (above the original 1-2’) is required in high angle(>25º) wells, in cross flow environment, or when multiple open perforation zones exist. Locate the end of the bailer 2 feet above the vent valve to dump. If the hole angle is higher than 60º and annular spacing will allow passage of the bailer string, locate the bailer bottom 2-3 feet above the basket to dump bridging material. NOTE: Avoid contact with the basket. Contact to the metal petal basket can cause damage.

4.7. Make dump bailer runs to place initial cement volume until it is within 12 – 18 inches below the vent ports prior to closing the vent valve (this is the base plug). Dump cement as close to top of previous run as possible. As with bridging material, if annular spacing allows, locate the end of the bailer 1-2 feet above the top of the previous run. Pull off bottom at < 30 fpm. Maintain this speed on all cement bailer runs within 1000 feet of plug.

4.8. Wait a minimum of 18 hours after the last dump bailer run before closing the vent valve (unless using Ultra Set Activator to eliminate waiting time, see product information on Ultra Set Activator for details).

4.9. Make up tool string consisting of CCL, weight bars, centralizer (s), and Lead Impression Block (LIB) and run to top of plug. Set down atop vent valve to close vent, it is not necessary to beat down with excessive force.

4.10. Make additional bailer runs as required to achieve plug height.

4.11. Wait a minimum of 24 hours after the last dump bailer run before pressure testing the cement plug (unless using Ultra Set Activator to eliminate waiting time, see product information on Ultra Set Activator for details).
