ExploreAbout this exam
The Juru Bor (Driller) credential is a workplace certification for people who operate or supervise drilling equipment - typically on mineral exploration, water-well, geotechnical or construction rigs. "Juru Bor" is the Malay term for driller, so the exam is delivered in Malay and assumes you already work around a rig rather than learning the job from scratch. It tests whether you can run a hole safely and legally, not whether you can recite a textbook.
The syllabus spans eight areas: occupational safety, health and environmental regulation; drilling equipment, components and inspection; drilling fluids, circulation and wellbore stability; drilling operations and parameters; well control and kick detection; rigging, lifting and manual handling; emergency response, firefighting and first aid; and communication, teamwork and records. Safety and well-control topics carry the most weight, which reflects where accidents actually happen.
Preparation works best in layers. Start with the regulations and safety framework so later technical material has context, then work through equipment and fluids, and finish with well control and emergency response, practising the calculations and the decision sequences until they are automatic. Candidates who already hold site safety inductions and rig-specific training arrive with a real advantage.

What you'll study
About Juru Bor (Driller) preparation
What format is the Juru Bor (Driller) exam?
It is delivered as multiple-choice questions in Malay, covering the eight published domains. The official body publishes the current question count, time limit and any practical assessment component on its website - check there before you book, because these details change between sittings and this page does not state them.
How difficult is the exam?
Candidates with regular rig exposure usually find the equipment and operations questions straightforward and struggle with well control calculations and regulatory detail. The exam rewards people who can apply procedures under pressure rather than memorise lists, so expect scenario-style questions where two answers both sound plausible.
What happens if I fail - can I retake it?
Retake rules, waiting periods and any additional fees are set by the certifying authority and are not fixed across providers. Confirm the current retake policy directly with the official body before sitting, and ask whether a failed attempt affects your eligibility window for the next one.
How long is the certification valid?
Validity periods vary by issuing body and by the safety regime in your jurisdiction. Check the official site for the current validity term and for any refresher or reassessment requirement. Diarise your expiry date as soon as you are certified - letting it lapse mid-project creates problems for you and your employer.
In what order should I study the eight domains?
Start with occupational safety and environmental regulation, because the legal duties frame everything else. Move to equipment and inspection, then fluids and wellbore stability, then drilling operations and parameters. Finish with well control and emergency response, which draw on all the earlier material, and revise communication and records last as quick consolidation.
What are the most common failure modes?
Three recur: weak well-control arithmetic, especially converting between mud weight, pressure and kill-margin terms; confusing inspection intervals and rejection criteria for drilling components; and misreading regulatory duties between employer, supervisor and driller. Practise calculations with units written out, and learn who is responsible for what.
Do I need practical rig experience to pass?
The exam assumes familiarity with rig terminology, equipment layout and routine procedures. Candidates without hands-on exposure often misread questions about sequencing and inspection because the wording presumes you have seen the task done. If you lack experience, spend time on a site or with realistic simulations before sitting.
How should I handle calculation questions under time pressure?
Write the formula and units before substituting numbers, keep a consistent unit system, and sanity-check the answer against what you would expect on a real well. If a question stalls you, mark it and move on - returning with fresh eyes beats burning minutes on one item.
