Thus, decreasing unit drilling cost is considered a reflection of performance improvements. These benchmarking methods are based on cost exposure as measured by nonproductive time, cost per barrel of oil expected, cost per ...
Innovative PDC bits, downhole tools for oil and gas directional drilling with high ROP, and high durability.
3.2 Overview of directional drilling Today, directional drilling is used for many purposes, some of which include the following: i. Multiple well from a single platform or single well: This is the most economical way to develop offshore fields. Since the cost of drilling is high, many wells...

contacting devices that externally push the drill string toward a desired orientation. The invention provides a steering tool having lower cost, greater reliability, and longer life than the steering tools of the prior art, combined with the ability to improve upon long reach angular drilling in ...
Furthermore, directional drilling can be much more cost-effective. Oil rigs and their staff sometimes have day rates that are upwards of hundreds of thousands of dollars. With directional drilling, one rig alone may be able to work up to five or ten square miles (compared to having a dozen...
A substantial improvement in drilling efficiency was realized using a combination of jetting and steerable drilling to kick off and drill the wells on Conoco Indonesia Inc.'s Belida 'A' Platform in the South Natuna Sea. Significant time and cost savings were achieved against initial AFE estimates...
