Static electricity can be reduced or eliminated by simply draining off the static charge.

True or False?

True

When using the Cycle/Purge gas sampling method, prior to sampling:

The cylinder must be heated to a temperature higher than that of the gas to be sampled

100

What is the first step in completing a vapour pressure test of liquefied petroleum gas?

Equipment must be thoroughly cleaned and assembled correctly

100

When sampling sweet gas, if there is sufficient space to connect the sample cylinder directly to the sample valve using a close nipple, the sample line

May be eliminated

100

The drilling procedure where the motor is mounted below the traveling block to enable the pipe to be turned from above rather than on the floor is known as the

Top drive procedure

200

When loading tankers, it is important to understand that bonding eliminates a potential difference between ____________________, while grounding eliminates a potential difference between ___________________.

two different objects, an object and the earth

200

The Liquid Displacement method is not normally recommended for gas sampling.

True or False?

True


200

The pressure of the sample is recorded prior to removing the apparatus from the water bath and then, when consecutive readings are constant, the pressure is reported as the:

Uncorrected LP-Vapour pressure

200

For samples obtained using the evacuated cylinder method, it is extremely important to take an outage before transport.

True or False

False

200

Blowout preventers are designed to close the well if the drill pipe is either in or out of the well. If there is no pipe in the well during a blowout, the wellbore will be completely shut off by the

Blind rams

300

Any conductive object that is grounded to the earth can become charged if near a steam jet

True or False?

False

300

The last step in a hydrocarbon gas sampling procedure is to:

Record the sample information

300

You are reviewing test results from a LPG sampling. Two samples were collected by two different operators in the plant and analyzed in two separate laboratories. The sample was taken from the same test material but the difference in the reported LP-Gas vapour pressure was 4.2 psi. What should be your response to this analysis report?

Reject the test results as being too different to be acceptable and re-do the test

300

If free water is produced, a water sample should be obtained in a

Plastic bottle from the separator

300

The special drilling procedure which utilizes a large spool of metal tubing for the drill pipe and a mud motor at the bottom of the coil of tubing to turn the drill bit is called the:

Coiled tubing drilling procedure

400

The potential for static charges to build up is greater in environments with:

Low humidity


400

The recommended method for company personnel to obtain gas and liquid samples is the:

Evacuated Cylinder

400

The pressure of the sample is recorded prior to removing the apparatus from the water bath and then, when consecutive readings are constant, the pressure is reported as the:

Uncorrected LP-Vapour pressure

400

Imagine that you have been asked to install a liquid sampling valve on a horizontal pipe upstream of the pressure-reducing valve in order to obtain samples from a separator. Where should the sample point be located and why?

On the underside of the pipe to avoid collecting any gas that could get trapped in the upper side

400

What does the The swivel do?

Supports the load of the drill stem during drilling

500

Imagine that you are part of a crew that is cleaning gasoline storage tanks. Your crew is finished, but your supervisor insists that you all check the area to ensure that all tools have been removed from the tank. Why is this so important?

Because the tools can become spark promoters

500

The Evacuated Cylinder gas sampling method has what disadvantage while sampling?

Sample will be contaminated with air if vacuum is lost

500

LP-Gas vapour pressure test results are reported in terms of:

kPa at test temperature

500

To prevent extra lab costs for stock tank oil sample analysis, the lab must be specifically requested to analyze the stock tank sample for only

Density, sulphur content, and B.S. & W

500

On newer drilling rigs the complex rotary system is replaced by a

Both Top-drive system and power swivel
