Coiled tubing drilling (CTD) is an innovative method employed in the oil and gas industry for drilling and completing wells. This technique utilizes a continuous length of small-diameter steel pipe, known as coiled tubing, which is spooled onto a reel and inserted into the wellbore. Unlike traditional drilling methods that use jointed pipe, coiled tubing allows for various operations to be performed efficiently and effectively, making it a versatile choice for many applications.
