Toolpusher – Technical Questionnaire

#1. When selecting a set pressure limit for a pop-off valve on a mud pump, what is the rating working pressure based on?

The burst pressure of the mud pump piston (head).

The burst pressure of the mud pump liner.

The rated working pressure of the mud pump.

The rate working pressure of the surface line on the rig being pumped through.

The rated working pressure of the BOP if the well needs to be controlled through the Kill Line.

#2. What is the leading cause of workplace injuries?

Slips, trips and falls

Hand injuries

Fatigue and overexertion

Lack of documentation

Procedures not followed

#3. What is the main purpose of the Occupational Heath and Safety Act?

Protect workers

Establish procedures for identifying and dealing with workplace hazards

Enforcement of non-compliance

All the above

#4. What are two types and characteristics of stuck pipe?

Select all that apply:

Differential sticking: This occurs when the drill pipe becomes stuck due to differential pressure between the wellbore and the drilled formation. It can happen when the drilling fluid filtrate invades the permeable formation, causing it to swell and adhere to the drill pipe.

Mechanical sticking: This type of sticking occurs when the drill pipe becomes lodged or wedged in the wellbore due to mechanical factors such as wellbore geometry, wellbore stability issues, or debris/cuttings accumulation.

All of The Above

#5. When a piece of equipment requires a service such as a hydraulics or a pressure pumps, what must be done before the work can begin?

Turn off the equipment and the switch.

Notify a supervisor before shutting down the equipment. Turn off the equipment at the main breaker. Lock out and tag out the main power source. Function test the controls for the equipment before the work begins.

Unplug the equipment from the panel.

Notify a supervisor before shutting down the equipment. Complete a Permit to work with Pre-job inspection. Lock out and tag out the equipment. Function test the controls for the equipment before the work begins.

#6. What is a safety matrix and what is the tool used for?

A safety matrix is a tool that is used during risk assessment to define the level of risk by considering the category of probability or likelihood against the category of consequence severity.

A safety matrix is read and reviewed at a pre-task meeting. The document breaks down the steps, hazards, appropriate supervision, PPE required, Highlights permits and supporting documentation required, and corrective actions needed in place to complete a task safely.

A safety matrix is a tool used by organizations to assess and manage safety risks associated with the projects, operations, or jobs.

All the above.

A and C

#7. What is a string float used for?

It is used to trap air in the drill string to lighten the hookload when tripping.

It is to prevent flow from the annulus into the Drill pipe while tripping in the hole.

Its primary function is to serve as a check valve, permitting the downward flow of drilling mud through the drill string but preventing any unwanted fluid from flowing back up into the drill string.

#8. When conducting a pressure test on the BOP, surface lines, choke Safety valve and the inside BOP, how should pressure be applied to ensure a competent test is completed as per API standard?

Pressure should be applied from the direction of flow from the wellbore.

Pressure should be applied from a side entry sub with a Safety valve on top and down through a ported test plug.

Pressure should be applied from the choke manifold to test the choke, HCR, BOP RAMs and Annular element.

Pressure should be applied from the mud pump manifold to the BOP through the kill line.

A and B

#9. Select the primary Safety Drills routinely conducted on a Drilling Rig.

BOP Drill

Trip Drill

Strip Drill

Pit Drill

Choke Drill

Fire Drill

Man Down Drill

Threat to Security Drill

Muster Drill

All of The Above

#10. What can happen to a Drill pipe thread connection if the Manufacturers torque specs are not achieved when making up?

The Manufacturers torque specifications are a recommended torque but can not always be achieved if the rig equipment can not torque high enough.

Anything over 25,000ft/lbs is the minimum requirement.

If the optimum torque is not achieved, the connections can over-torque down hole from reactive torque, directional motor stalling, stick and slip, jarring with torque applied to the drill string, and when drilling through aggressive formations were high torque downhole is observed.

Connections can back out when tripping in the hole and drilling.

Connections should not be torqued to the recommended torque value because it wears out the threads and becomes difficult to break the connections when tripping out of the hole.
