Consider the following pairs:1. Rotary Drilling: Uses a rotating dril...
1. Rotary Drilling: Correctly matched. Rotary drilling indeed uses a rotating drill bit attached to a drill string, cooled by drilling mud to cut through rock formations.
2. Percussion Drilling: Incorrectly matched. Percussion drilling, also known as air hammering, uses high-pressure air to power a hammer that efficiently breaks rock and flushes out cuttings, not hydraulic pressure.
3. Geophysical Surveys: Correctly matched. Geophysical surveys do employ seismic, magnetic, and gravitational methods to map subsurface structures.
4. Hydraulic Fracturing: Incorrectly matched. Hydraulic fracturing, commonly known as fracking, enhances fluid flow in rock formations using pressurized liquid, not high-pressure air.
Thus, only pairs 1 and 3 are correctly matched.
2. Percussion Drilling: Incorrectly matched. Percussion drilling, also known as air hammering, uses high-pressure air to power a hammer that efficiently breaks rock and flushes out cuttings, not hydraulic pressure.
3. Geophysical Surveys: Correctly matched. Geophysical surveys do employ seismic, magnetic, and gravitational methods to map subsurface structures.
4. Hydraulic Fracturing: Incorrectly matched. Hydraulic fracturing, commonly known as fracking, enhances fluid flow in rock formations using pressurized liquid, not high-pressure air.
Thus, only pairs 1 and 3 are correctly matched.
