30” CASING JETTING & 26" HOLE DRILLING PROCEDURES
30” Casing Jetting and 26” Hole Drilling Procedures

1) Establish length of 30” casing to be jetted. Paint the top 4m WHITE with 1m spacing bands (in Black) from the Casing head (or other reference point) down the GRA and onto the casing. It is also helpful to likewise paint the bottom 3-4m from the casing shoe (makes observation by the ROV much easier).

2)Take EXACT measurements of casing length from hang-off point to shoe.
