Why Oriented Perforations?

• To Perforate away from Fiber Optic cable installed outside production casing in cased and perforated completions

¼ or 1/8” standard control line used to deploy fiber, how do we locate it to orient the perforation guns?

• After cementation, the cable may cause a streak with no cement that can be detected by ultrasonic imaging tools (not warranted)

• Electromagnetic logging tools can detect the cable if magnetic properties enhanced

• If cable position known from surface, orientation can be done without the need for mapping

Electric line convey

Uses motor to locate and position guns based on high electromagnetic signal

Limited gun size

Limited in length of perforation

High risk in vertical wells due to tool sensitivity to centralization

Tubing convey

Uses mechanical orientation tool to position guns based on pre-set casing profile

Carry bigger gun size

Can perform long perforation interval in one go

Deviation is not necessary but high accuracy in cable positioning w.r.t. orientation profile is critical (rig operation)

7" 23# K55 LTC csg @ 958m Fixed TD

Changes to standard well design and perforation strategy:

• Surface casing ID increased to allow for larger production hole size (larger cement sheath expected)

• Production casing run with FO cable and cable locator profile (depth based on target perforation interval)

• Underbalance perforation not possible, however, dynamic underbalance considered after initial injectivityassessment

• Shot density reduced by half

• Shot angle limited to 90deg coverage

Risk: changes to injectivity/productivity and fluid velocity Evaluate well performance

Job Execution (Deviated Well Application)

Outline program

• Scrapper run

• Jetting and dummy run of mechanical positioning tool

• Electromagnetic tool mapping and perforating (0deg phasing)

• Ultrasonic tool mapping and confirmation of 1st perforation

• Tubing convey perforation (0, +/-45deg)

• Temperature survey to confirm performance of perforation

Job Execution (Vertical Well Application)

Outline program

• Scrapper run

• Jetting and dummy run of mechanical positioning tool

• Ultrasonic tool (detect cable position at casing profile location)

• Tubing convey perforation (0, +/-30deg)

• Temperature survey to confirm performance of perforation

FO cable had not rotated w.r.t. casing profile

• Use special rotatable scraper to avoid issues with casing profile

• Run with location tool as dummy run to clean & confirm casing profile clear from any debris or cement.

• Connect the guns together in perforation workshop and make scribe to avoid misalignment while running the guns in hole.

• Ensure drift ID of the X/O below CSLT more than fishing tool for drop bar.

• Displine sub should be within 10 deg orientation range to minimize misalignment between the guns & CSLT.
