Sample Juru Bor (Driller) Practice Questions

Try these sample questions to review concepts for the Juru Bor (Driller) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Why should the rig cellar and other low, enclosed spots be treated as high-risk areas when a well may release hydrogen sulfide (H2S)?
A.H2S is lighter than air, so it collects under the rig floor before rising
B.H2S is heavier than air and can pool in low, poorly ventilated spaces
C.H2S only becomes toxic after it mixes with water standing in the cellar
D.H2S condenses into a liquid at normal air temperatures and drains down into the cellar
Explanation: Hydrogen sulfide is heavier than air, so it can accumulate in low-lying, enclosed and poorly ventilated places such as cellars, pits and enclosed shaker areas. Those spots can hold a dangerous concentration even when the open rig floor seems clear, which is why detection and entry precautions focus on them.
2A new floorman says he will rely on the rotten-egg smell to warn him if hydrogen sulfide (H2S) is present. Why is that unsafe?
A.H2S has no odour at any concentration, so it can never be smelled
B.H2S can only be smelled once it has mixed with natural gas or crude oil vapour at the flowline
C.The smell is reliable, but only when the air is still
D.High or prolonged exposure can deaden the sense of smell while gas is still present
Explanation: OSHA notes that H2S can be smelled at low levels, but continuous low-level exposure or higher concentrations cause loss of the ability to smell it, and at high concentrations smell can be lost instantly. Crews must rely on gas detectors and alarms, never on odour, to judge whether H2S is present.
3An H2S alarm sounds on a drilling location. Where should personnel who are not assigned to well-control duties go?
A.Upwind or crosswind of the source, to the designated safe briefing area
B.Downwind, so the wind carries the gas away from them
C.Into the rig cellar, which is sheltered from the wind
D.Up to the monkey board, because heavy gas stays low and the derrick is above the plume
Explanation: API RP 49 practice is to designate at least two briefing areas so that one is always upwind, with windsocks showing wind direction. On an alarm, personnel move upwind or crosswind away from the release to the safe briefing area, where everyone is accounted for.
4A crew member has collapsed near the shale shakers and H2S is suspected. What must rescuers do before approaching the casualty?
A.Hold their breath and drag the casualty out as quickly as possible
B.Cover their nose and mouth with a wet cloth to absorb the gas
C.Put on self-contained breathing apparatus and work with a partner before entering
D.Wait until a portable gas detector held at the edge of the area reads zero before anyone goes near
Explanation: Rescuers who rush in without respiratory protection often become extra casualties. OSHA treats atmospheres above 100 ppm H2S as immediately dangerous to life and health and requires self-contained breathing apparatus, so rescuers put on breathing apparatus, use the buddy system and then move the casualty to fresh air.
5Before a non-routine job such as nippling up a BOP stack, the driller leads a Job Safety Analysis (JSA). What is its main purpose?
A.To record crew attendance for the daily drilling report
B.To replace the permit-to-work system, since a JSA already lists the job's hazards
C.To estimate how long the job will take for rig scheduling
D.To identify each step's hazards and agree controls before work starts
Explanation: A JSA walks the crew through the task step by step, identifies what could go wrong at each step, and assigns controls and responsibilities before anyone starts. It supports, rather than replaces, permits to work and supervision.
6Under API RP 505, which description defines a Class I, Zone 1 hazardous location around a drilling rig?
A.Ignitable concentrations of flammable gas or vapour are present continuously or for long periods during normal operation
B.Ignitable concentrations are likely in normal operation, or may occur often during repair or maintenance
C.Ignitable concentrations are not likely in normal operation and, if they do occur, persist only for a short period
D.Flammable gas is not expected, so general-purpose electrical equipment may be used
Explanation: API RP 505 defines Zone 1 as a location where ignitable concentrations of flammable gases or vapours are likely under normal operating conditions, or may exist frequently because of repair or maintenance. Around a drilling-only operation, the area near the well centre and an enclosed shaker room are typical Zone 1 areas, so electrical equipment there must be suitable for that zone.
7Under Peraturan Menteri ESDM No. 32 Tahun 2021, what is the role of the Kepala Teknik in oil and gas business activities?
A.A government civil servant who carries out technical inspections and safety checks of installations
B.The most senior driller on each rig crew
C.The person responsible for Keselamatan Migas at the contractor or licence holder
D.The official who ex officio leads the ministry's oil and gas inspection function
Explanation: Permen ESDM 32/2021 defines the Kepala Teknik as the person responsible for Keselamatan Migas (oil and gas safety) at a Kontraktor or Pemegang Izin Usaha, and every contractor must have one. Keselamatan Migas covers worker safety, installation and equipment safety, environmental safety and public safety.
8Under Peraturan Menteri ESDM No. 32 Tahun 2021, who formally determines (menetapkan) a contractor's Kepala Teknik and any deputy Kepala Teknik?
A.The Kepala Inspeksi Migas
B.The chair of LSP PPSDM Migas
C.The Minister of Manpower
D.The drilling contractor's toolpusher
Explanation: Article 6 of Permen ESDM 32/2021 requires the Kepala Teknik to be competent in oil and gas safety supervision, allows a competent deputy to be appointed, and states that both are determined by the Kepala Inspeksi. The Kepala Inspeksi must also approve any plan to have more than one Kepala Teknik in a single work area.
9Under Peraturan Menteri ESDM No. 32 Tahun 2021, how quickly must the Kepala Teknik report a work accident (kecelakaan kerja) to the Kepala Inspeksi?
A.Within 1 × 24 hours by electronic message and within 2 × 24 hours in writing
B.Within 7 days, in writing only
C.In the routine monthly report of safe working hours
D.Every three months, together with the report on worker competence (kompetensi para pekerja)
Explanation: Article 7 requires work, installation and environmental accidents, public-order disturbances and unplanned shutdowns to be reported within 1 × 24 hours by electronic message and 2 × 24 hours in writing. Routine safe-working-hour reports are due by the second week of the following month, and worker-competence reports every three months.
10Why must drilling personnel in Indonesian oil and gas operations be assessed against SKKNI standards instead of treating certification as optional?
A.Because IWCF rules require an SKKNI certificate for every driller working on an Indonesian rig
B.Because a BNSP certificate replaces the need for separate company well-control training
C.Because an ESDM regulation makes SKKNI mandatory in oil and gas business activities
D.Because SKKNI certificates are needed only for work on offshore rigs
Explanation: The LSP PPSDM Migas Juru Bor scheme cites Peraturan Menteri ESDM No. 5 Tahun 2015, which makes SKKNI mandatory (secara wajib) in oil and gas business activities, together with Kepmenaker No. 134 Tahun 2021 for the onshore drilling standard. Competence is therefore assessed against those SKKNI units by a BNSP-licensed LSP.
