glasses, etc. to visitors
2) Brief a visitors
3) Ensure safery briefing to the cruew before starting the tour
4) Check equipments and alarms
5) Attend all drills and monitor response of crew
6) Check the conditions of lifting equipments and anchors
7) Prepare a job safery analysis (JSA) before job starts
8) Ensure rig site is clean and tidy
9) Test fire pumps and hoses daily
10) Report near misses
List 5 pieces of safety equipment on a rig and their function:
Equipment Purpose
1) Personal H2S detectors -to detect h2s gas in a certain zone
2) Fire extinguisher - to escape the fire
3) Smoke detectors - to detect smoke
4) First aid kid - to help a person who have injury
5) Geronimo - evacuation line for derrickhand
What are 3 examples of the legal impact to an operating company in the event of a blowout and oil spill?
1) their license can be cancelled
2) they will pay compensation to people, who suffer from that
3) Inspection and document, HSE control from goverment will take place. May go to jail
Put in order positions: (they are 6)
1) Toolpusher
2) Driller
3) Derrickhand
4) Motorman
5) Roughneck
6) LeaseHand
What are the 3 highest priorities( in order) when planning a well?
1) HSE
2) Well integrity
3) Time = money
What are 3 responsiblities of the drilling engineer?
1) Prepare drilling program
2) Designs the well
3) Improves performance
List 4 types of training personnel on drilling righs should have:
1) H2S training
2) Fire drills
3) First aid training
4) Evacuation drills
What 2 items can be found in an emergency responsible plan(ERP) ?
1) Steps what actions to take
2) Telephone numbers (Firefighter, ambulance etc)
BOP when PIPE -> TOP and blind -> bottom?
Advantages:
PI - we able to circulate and kill the well
PO - we can change all above blind rams
Disadvantages:
PI - cannot replace equipment below pipe rams
PO - cannot circulate
BOP when PIPE -> BOTTOM and blind -> top?
Advantages: PI - can change all equipment above pipe ram PO - pump and fluid up down (circulate) Disadvantages: PI - not able to circulate PO - not able to change and maintain
Define Hard shut in and advantages
1) HCR is closed
2) BOP is closed
Adv and disadvantages of HARD shut in
Adv: minimize influx (kick size)
Disadva: water hammer effect
Define Soft Shut In
1) Choke valve is open
2) BOP is closed
3) then slowly close choke valve
Adv and disadvantages of SOFT shut in
Adv: control to not exced macp
less pressure pulse
Disadv: let the bigger kick volume
HCR stands for
High Closing Ratio
When doing site survey name 2 considerations:
1) location
2) environment
Name 2 consideration when preparing the directional plan?
Torque and drag
Casing set depth ???
List 2 requirements an operator needs to submit in a well license application:
1) Technical considerations
2) Environmental considerations
List 5 parts/ sections of a driling program:
1) BHA (drill string, bits etc)
2) Casing details
3) Cement details
4) Mud properties
5) General information
2 reasons why drilling contractor is better
1) Experienced employee
2) For OPCO it is temporary work so there is no need to hire employee, buy equipment.
Describe how an incompent surface soil may cause safery concerns for a rig operation:
Incompent formation may cause of wash out and BOP and surface equipment can sink, even drilling rig can
Name 3 examples where computer software can help optimize well design:
1) For drilling report (Open Wells)
2) Selecting of casing depth (Casing Seat)
3) For BHA analysis, torque and drag studies , surge and swab press. calculation, well control and stuck pipe analysis, and critical rotary speed calc( Well Plan)
