Checklists

Rig up checklist Rig down the rig elevator and bails, make sure the iron roughneck has been laid out Remove the saver sub using the pipe handler of the top drive (rig procedure). Check the make-up torque setting of the pipe handler prior to removing the saver sub. Verify that the pipe handler stays inline Running Casing with Weatherford Overdrive system – Best Practices

Analyse logging and survey data from original hole Select base of higher ROP interval as sidetrack point (probable over gauge hole overlying gauge hole) Sidetrack point with inclination or dog-leg in original hole will be advantageous Optimise cement slurry recipe (potential for gas cut) Confirm cement quality by drill off test BHA for first attempt Sidetracking Best Practices

Operations Engineer to organise pre-job meeting at the rig site with rig and office personnel to discuss the job objective and hazards. Pictorials to be prepared and discussed during pre-job meeting so it can be followed during rigging up. When MRX logging is required, ensure that two units available on location prior to starting the Logging Operations Best Practices

Operations Engineer to organise pre-job planning meeting at the rig site, with rig and office personnel to discuss the job objective and hazards. Sections are picked up in 30-foot lengths, so the steps outlined should be multiplied for a given core barrel length. Check if hole conditions allow run 81 meter core barrel. Do not Coring Preparation Checklist/ Best Practices

1. Preparation The Drilling Supervisor shall approve and provide written instructions to the Contractor Toolpusher prior to any trip out of the hole. These instructions shall include the: sequence of operations  i.e. flow check, circulate bottoms up, drop survey, etc. maximum allowed overpull procedures if tight hole is encountered maximum running/pulling speeds preparation of equipment Tripping Operations – Best Practices

This checklist is primarily concerned with the engineering design of the well.  It is not intended to be a project planning tool covering different well, rig and time related activities such as the submission of the operational information to all the necessary regulatory authorities. It is to be completed concurrently with the compilation of the Well Planning Checklist

Wear Bushing retrieved Pre-job safety brief held with all parties Back up float and shoe equipment in store or easily available All float equipment is PDC drillable and written on the tools Tailing device available if required Casing crew checked out tongs/power pack Bakerlock/wire brush/barite available on rig floor Float equipment checked out  Floats to Casing running checklist

The Superintendent or Senior Operations Engineer shall conduct a pre-spud meeting on the rig with all relevant personnel directly or indirectly involved with the operations. The appropriate Drilling Supervisor and Operations Engineer shall also attend. A list of attendees shall be taken and recorded with the minutes. Agenda At the pre-spud meeting, held in the Pre-Spud Meeting on Site
