Why has the percussion drilling method, known as the cable tool method, waned in popularity?

• A. It is too expensive
• B. Faster and easier methods have been developed
• C. It is more labor-intensive
• D. Regulatory changes made it obsolete

Answer: (B)

The reason the percussion drilling method, also known as the cable tool method, has diminished in popularity primarily revolves around the advancements in drilling technology that have led to faster and easier methods. Over the years, more efficient techniques, such as rotary drilling, have emerged, significantly reducing the time and effort required to reach target depths. This shift allows for quicker project completion and often results in lower labor costs and improved overall productivity. While factors like cost, labor intensity, and regulatory changes can contribute to the preference for newer methods, the standout reason remains the availability of drilling technologies that streamline the process and enhance efficiency. The cable tool method requires significant manual labor, including the repeated raising and dropping of a heavy drill bit, which is inherently more time-consuming compared to modern methods. As a result, many operators have opted for more advanced techniques that support faster drilling and operational ease.
