At present, the drilling of oil and gas reservoirs in deep, ultra-deep, and complex strata or
deep water suffers from some problems such as difficult operations, long periods, and …

Since oil and gas companies realized that drilling more wells, which are frequently
characterized by narrow pressure margins, is the next stage in the exploration and …

For many years the oil industry has been limited by the fact that measurements are only
taken at the BHA and at surface during well construction operations. This has led to a …

High-speed drill-string telemetry technology is being adopted with increasing frequency into
challenging drilling environments around the world. In addition to allowing instantaneous …

The drilling industry is still plagued by challenges such as losses, packoff, hole-cleaning
issues, and wellbore instability. Research and development using data from multiple …

Measurements made with wireline logs are often used as the reference for well depth.
However, differences are usually noted between wireline depth (" Logger's Depth") and …

The near bit engineering parameters are important factors which can affect drilling safety.
With the advances of drilling technologies, such as ultra-deep well technology and extended …

Monitoring the borehole condition during the ongoing drilling process is essential for a
successful and safe drilling operation. The drilling industry has developed monitoring …

When it comes to optimizing drilling, the focus is on running the bit into the well and
performing the drilling efficiently. Included in this are methods for optimizing rate of …

The objective of this paper is to discuss and outline the invention of the data while tripping
