What's the first thing you do when you arrive to the rig?
Handover
Chech well program
Chech well control equipment certificates
Chech Bop &choke manifold line up
Check History
Do check drillers and AD's for their checklists or you depend on feedback?
Not every thing..but I double check always on well control equipment , like Bop line up and when tripping I check their trip sheets and having safety valves ready and in place
What precautions do you take when working with cement stinger?
- to have a centerlizer to keep the pipes centered
-to make sure that the saels are in good condition to avoid leaks.aftr stinging in the level shouldn't change.
-to fill the casing before cementing to avoid casing collapse.
What is the max. Time for testing Bop?
-two weeks asper aramco policy anx we can ask for 2 days extension in some cases
What is the max. Mud weight you used?
- 155 PCF using hematite.
Oil or gas wells?
- Gas exploration wells
Do you have fishing tools on the rig , owned by the rig?
Yes and we keep an updated invintory of it. all of that provided by eng Baher
provided by eng Baher global energy talent :
1- number of wells and max depth you drilled?
2-number and sizes of casing you used.?
- 34,24,18 5/8,13 3/8,9 5/8, 7,
4
3- tell me what you know about LOT?
- drill 10-15' new formation, circulate for even mud, pull inside shoe, use cmt pump to get L.O.PRESS
4- what is L.O.PRESS usefull for while killing a well?
-to know MAASP, MAMWT,and when influx is below shoe we dont allow surface press to increase more than maasp ..but when influx is inside casing we can allow that.
5-what instructions do you give the drilling if going to drill high pressure formation?
- keep an eye on Mwt, set alarms,flow check if any doubts or drilling breaks, shut the well in if positive, make sure BOP and manifold lined up........etc
6-how often you test BOP & at what pressures?
-every 2 weeks..may have 2 days extension. ..300/12500 psi
7_ what stacks you have and press rating?
- 26 3/4".......5000 psi
13 5/8" ......15000 psi
8-tell me the different methods to kill the well?
-driller ,W&W , concurrent
8-tell the difference between driller and W&W?
- .2 cycles..1 cycle
9-what types of drilling fluids you use on the rig?
- oil base,water base,brine water
10 -why do we use oil base muds?
To avoid contaminating pay zones
11-What safety meetings do you attend on the rig?
- prejob,pretour,pre rig move,prespud,LPT........etc
