Pre job Safety Meeting

Make sure around casing is excavated 8 feet square around wellhead with & sloped sides with one or two gradual inclines or steps.

Test around casing for any venting gas.

Weld collar on side of casing so the Hot Tap Crew can drill into inner & outer casing to determine any casing pressure is present.

If casing has no pressure & has no venting H2S, LEL can proceed with cutting casing.

Cut outer casing 1’ to 1 ½‘below inner casing to allow room for the inner slide on collar.

Cut inner casing 1’ to 1 ½‘above outer casing.

Slide inner casing collar on casing & level collar & tack weld.

Slide on outer collar & repeat same procedure as inner collar.

Find appropriate height for inner casing above Bowl Top when in place, min. of 1’ to 2 feet is sufficient.

Slide casing in inner collar and level casing & tack in place & weld 3 passes on top of collar.

Measure from inside of outer collar where casing will sit to top of Casing Bowl, “where consultant will determine where top of bowl sits” casing should be ½” to 1” above test hole pug on the inside of casing bowl.

Slide outer casing over inner casing into collar and level casing & tack in for spots adjacent of each other & weld 3 passes on top of collar to casing.

Preheat Casing Bowl to 350fh (measure temp with heat stick or heat gun.)

Slide bowl over outer casing to ½”-1” above test hole plug.

Level Casing Bowl & weld 1” long tack’s adjacent of each other.

Weld 3 passes on bottom of Casing Bowl & multiple passes on inside of Casing Bowl.

Inspect welds for job quality by testing with Nitrogen @ 10000kpa for 15 minutes.

Wrap up and make sure all objects & items are out of excavation.
