Fractal geometry has proven to be a powerful tool for modeling natural phenomena. Using discrete approximations to fractional Brownian motion over a finite grid plane, computer graphics terrain-rendering algorithms are able to generate highly realist

This paper analyzes representative samples of downhole and surface measurements collected during a sidetrack operation with a coiled tubing drilling unit. The downhole data are classified into operational windows such as drill ahead, running in hole

Summary Coiled tubing (CT) drilling is a rapidly growing new technology that has been used for shallow new wells and reentry applications. Averaged over the last 4 years, the number of wells directionally drilled with CT has doubled each year from 3

Reliable, low cost coiled tubing window milling technology has become the cornerstone of ARCO Alaska's coiled tubing sidetrack program at Prudhoe Bay. ARCO began to investigate coiled tubing drilling technology in 1989. The program grew into an aggre
