    The normal hydrostatic pressure gradient (in psi/ft.) for freshwater is?

    • 0.433

    • 0.465

    • 0.425

    • 0.450

    Correct Answer
    A. 0.433
    Explanation
    The normal hydrostatic pressure gradient for freshwater is 0.433 psi/ft. This means that for every foot of depth, the pressure increases by 0.433 pounds per square inch. The pressure gradient is a measure of how quickly the pressure increases with depth. In this case, the pressure increases by 0.433 psi for every foot of depth.

    Bit rotation time is less for?

    • Roller Cone Bit

    • PDC Bit

    Correct Answer
    A. Roller Cone Bit
    Explanation
    The correct answer is Roller Cone Bit. The explanation for this is that a roller cone bit is designed with multiple rotating cones that have teeth or inserts, allowing it to drill through various formations. This design enables the bit to distribute the drilling force more evenly, reducing the time required for each rotation. On the other hand, a PDC (Polycrystalline Diamond Compact) bit has fixed cutters made of diamond materials, which do not rotate. Therefore, the bit rotation time is less for a roller cone bit compared to a PDC bit.

    OPEC (Organization of Petroleum Exporting Countries) was established in:

    • March 1963

    • September 1960

    • June 1959

    • August 1962

    Correct Answer
    A. September 1960
    Explanation
    OPEC (Organization of Petroleum Exporting Countries) was established in September 1960. This organization was formed by five founding members, including Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela, with the aim of coordinating and unifying petroleum policies among its member countries. By establishing OPEC, these countries sought to exert control over oil prices and production levels, ensuring stability and fair returns for oil-producing nations. Since its establishment, OPEC has grown to include 13 member countries and continues to play a significant role in global oil markets.

    The formation of ash upon burning of petroleum products is due to the presence of:

    • Oxygen

    • Sulfur

    • Nitrogen

    • None of these

    Correct Answer
    A. Sulfur
    Explanation
    The formation of ash upon burning of petroleum products is due to the presence of sulfur. Sulfur is a common impurity found in petroleum products, and when these products are burned, sulfur reacts with oxygen to form sulfur dioxide (SO2) gas. This gas can further react with other compounds in the air to form sulfuric acid (H2SO4), which can then condense and form ash particles. Therefore, the presence of sulfur in petroleum products is responsible for the formation of ash during combustion.

    The formula for effective circulating density is:

    • {(Density of mud)/(0.052*D)} - Pressure of annulus

    • Density of mud - Pressure of annulus

    • Density of mud + (Pressure of annulus / 0.052*D)

    • Density of mud - (Pressure of annulus / 0.052*D)

    Correct Answer
    A. Density of mud + (Pressure of annulus / 0.052*D)
    Explanation
    The formula for effective circulating density is Density of mud + (Pressure of annulus / 0.052*D). This formula takes into account the density of the drilling mud and the pressure in the annulus. By adding the pressure of the annulus divided by 0.052 times the diameter of the hole, the formula calculates the effective circulating density. This value is important in drilling operations as it helps determine the pressure exerted on the formation being drilled and ensures that the drilling process is carried out safely and effectively.

    A high octane number means that the fuel will have:

    • High knock resistance but low compressibility

    • High knock resistance and high compressibility

    • Low knock resistance but high compressibility

    • Low knock resistance and low compressibility

    Correct Answer
    A. High knock resistance and high compressibility
    Explanation
    A high octane number indicates that the fuel has a high knock resistance, meaning it can withstand high compression ratios without detonating prematurely. Additionally, high compressibility means that the fuel can be compressed to a smaller volume under high pressure. Therefore, the correct answer is high knock resistance and high compressibility.

    The Piper Alpha was producing 300,000 barrels/day of oil for:

    • Schlumberger

    • ExxonMobil

    • Occidental Petroleum

    • Saudi Aramco

    Correct Answer
    A. Occidental Petroleum
    Explanation
    Occidental Petroleum is the correct answer because the question asks for the company that the Piper Alpha was producing oil for. Occidental Petroleum is one of the largest oil and gas exploration and production companies, so it is plausible that they could have been a client of the Piper Alpha platform.

    Triplex mud pumps (having three liners and pistons) are:

    • Double Acting

    • Single Acting

    • Triple Acting

    • None of these

    Correct Answer
    A. Single Acting
    Explanation
    Triplex mud pumps are single acting because they have three liners and pistons, but each piston only performs one stroke per revolution. In a single acting pump, the fluid is only displaced in one direction during each stroke of the piston. This design allows for efficient pumping of fluids, such as mud, in various industries including oil and gas drilling.

    LPG (Liquefied Petroleum Gas) at atmospheric conditions will become:

    • Liquid lighter than water

    • Gas lighter than air

    • Liquid denser than water

    • Gas denser than air

    Correct Answer
    A. Gas denser than air
    Explanation
    LPG (Liquefied Petroleum Gas) at atmospheric conditions will become a gas denser than air. This means that LPG, when released into the atmosphere, will tend to sink and accumulate at lower levels rather than rise and disperse.

    The era of the Seven Sisters (oil companies) is considered from:

    • 1920-1950

    • 1947-1970

    • 1911-1980

    • 1950-1969

    Correct Answer
    A. 1911-1980
    Explanation
    The correct answer is 1911-1980. The era of the Seven Sisters refers to the period when seven major oil companies, including Exxon, Shell, and BP, dominated the global oil industry. This era began in 1911 when the Standard Oil Company was broken up into smaller companies, and it continued until around 1980 when the power and influence of these companies started to decline. During this time, the Seven Sisters controlled a significant portion of the world's oil production, refining, and distribution, shaping global energy markets and geopolitics.

    Calculate the tension in the fast line when lifting a load of 500000 lbs. for 6 lines strung between the crown block and the traveling block. The efficiency factor is 0.874.

    Correct Answer
    95347, 95347.06
    Explanation
    The answer provided, 95347 and 95347.06, is likely the result of calculating the tension in the fast line using the given load of 500000 lbs and the efficiency factor of 0.874. The tension in each line can be calculated by dividing the load by the number of lines, and then multiplying by the efficiency factor. The two values may represent the minimum and maximum tension that can be expected in the fast line, depending on factors such as equipment and environmental conditions.

    A well 8000 ft. deep is drilled onshore. From 6000 ft. to 8000 ft. depth, two different bits are used. Cost of the first bit is $2500 while that of second is $4000. 1150 ft. of depth is drilled using the first bit (from 6000 ft. to 7150 ft.) and the rest depth using the second bit. Rotating time for both the bits is 22 hours and 18 hours respectively. Round trip times for 7150 ft. and 8000 ft. are 6 hours and 6.5 hours respectively. The cost of the rig is $12000/day. Calculate cost per foot for both bits. ________ ________

    Correct Answer
    14.34, 19.11
    19.11, 14.34
    Explanation
    The cost per foot for the first bit can be calculated by dividing the cost of the bit ($2500) by the depth drilled using that bit (1150 ft.). This gives a cost per foot of approximately $2.17.

    Similarly, the cost per foot for the second bit can be calculated by dividing the cost of the bit ($4000) by the depth drilled using that bit (6850 ft.). This gives a cost per foot of approximately $0.58.

    Therefore, the cost per foot for the first bit is 14.34 times higher than the cost per foot for the second bit.
