    No one could successfully drill wells with the rotary method without using

    • Drilling mud 

    • Bailer 

    • Water

    • Acid

    Correct Answer
    A. Drilling mud 
    Explanation
    Drilling mud is essential for the successful implementation of the rotary method in drilling wells. It serves multiple purposes such as cooling and lubricating the drill bit, removing rock cuttings from the wellbore, preventing the collapse of the well walls, and maintaining pressure control. Without drilling mud, the rotary method would not be effective as it would lead to difficulties in drilling, decreased efficiency, and potential damage to the wellbore.

    The magnitude of the pressure in the pores of a formation is known as the . a) Formation pore pressure b) Bottom-hole pressure c) Differential pressure d) None of the above

    • Formation pore pressure 

    • Bottom hole pressure 

    • Differential pressure 

    • None of the above 

    Correct Answer
    A. Formation pore pressure 
    Explanation
    The correct answer is formation pore pressure. This term refers to the magnitude of the pressure in the pores of a formation. It is an important parameter in the oil and gas industry as it helps determine the stability of the formation and the potential for fluid flow. Bottom-hole pressure refers to the pressure at the bottom of a wellbore, while differential pressure is the difference in pressure between two points. Neither of these terms specifically refers to the pressure in the pores of a formation.

    A fluid having a blend of viscous fluid behavior and of elastic solid-like behavior is called .

    • Visco-plastic fluid

    • Visco-elastic fluid

    • Thixotropic fluid

    • Rheopectic fluid

    Correct Answer
    A. Visco-elastic fluid
    Explanation
    A fluid that exhibits both viscous fluid behavior and elastic solid-like behavior is called a visco-elastic fluid. This means that it can flow and deform like a fluid under certain conditions, but also has the ability to recover its shape and resist deformation like a solid. This combination of properties makes it unique and differentiates it from other types of fluids such as visco-plastic, thixotropic, or rheopectic fluids.

    Which one is not a basic component of the rotary rig?

    • Kelly

    • Annulus 

    • Rotary table 

    • Drill pipe 

    Correct Answer
    A. Annulus 
    Explanation
    The annulus is not a basic component of the rotary rig. The other options, kelly, rotary table, and drill pipe, are all essential components of a rotary rig. The kelly is a long square or hexagonal pipe that is connected to the rotary table and is used to transmit power to the drill string. The rotary table is a large circular platform that supports the weight of the drill string and allows it to rotate. The drill pipe is a hollow steel pipe that connects the drill bit to the surface and allows for the circulation of drilling fluids.

    At the one end of the drillpipe there is the pin, which has the .

    • Female threads 

    • Male threads

    • Circular threads 

    • None of the above

    Correct Answer
    A. Male threads
    Explanation
    The correct answer is male threads. The pin at one end of the drillpipe typically has male threads. This allows it to be screwed into the box at the other end of the drillpipe, which has corresponding female threads. This threaded connection ensures a secure and tight fit between the two ends of the drillpipe, preventing any leakage or failure during drilling operations.

    Short teeth bits are used to drill

    • Hard rocks

    • Medium rocks 

    • Soft rocks 

    • None of the above 

    Correct Answer
    A. Hard rocks
    Explanation
    Short teeth bits are used to drill hard rocks because hard rocks require a more aggressive drilling action. Short teeth bits have a compact design with shorter teeth, allowing for increased impact and penetration into the hard rock surface. The shorter teeth also provide better stability and control during drilling, ensuring efficient and effective drilling in hard rock formations.

    In the West,......... was the first place of commercial production.  

    • United States

    • Canada

    • Brazil

    • France

    Correct Answer
    A. Canada
    Explanation
    Canada was the first place of commercial production in the West. This is because Canada has vast natural resources, including fertile land and abundant forests, which allowed for the development of various industries such as agriculture, forestry, and mining. Additionally, Canada's proximity to the United States and access to major waterways facilitated trade and the export of goods, further contributing to its early commercial success.

    In which case will fracture pressure become similar to overburden pressure?

    • Case of overpressured formations

    • Case of compacted formations

    • When all in-situ stresses are equal

    • None of the above

    Correct Answer
    A. When all in-situ stresses are equal
    Explanation
    When all in-situ stresses are equal, the fracture pressure will become similar to the overburden pressure. This is because in this case, the stress acting on the rock formation from all directions is balanced and equal, resulting in a uniform pressure distribution. As a result, the fracture pressure, which is the pressure required to create a fracture in the rock, will be similar to the overburden pressure, which is the pressure exerted by the weight of the overlying rock layers.

    . Low RPM and high ROP mainly indicate a) Hard formation b) Sandstone formation c) Carbonate formation d) None of the above

    • Hard formation 

    • Sandstone formation 

    • Carbonate formation 

    • None of the above 

    Correct Answer
    A. None of the above 
    Explanation
    The given question does not provide enough information to determine the relationship between low RPM (revolutions per minute) and high ROP (rate of penetration) with any specific formation type. Therefore, the correct answer is "None of the above".
