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 …

Managed Pressure Drilling (MPD) methods are used to drill wells with narrow pressure
margins in a safe, efficient, and economical way. Controlled Mud Level (CML) is a dual …

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

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 …

The prime objective of all oil and gas companies are to conduct various activities in a safe
and cost-efficient manner, while also paying attention to the long-term integrity of the wells …

Wired drill pipe (WDP) telemetry that transmits downhole data at 57,600 bits per second has
been successful in various applications throughout the world. This paper discusses how …

Wells drilled with nitrified drilling fluids require a solution for the transmission of
measurement-while-drilling (MWD) surveys, bi-directional communication with rotary …

Wired drill pipe (WDP) telemetry has been used in over 100 wells worldwide to create a
drillstring network that provides high bandwidth communications between tools deployed in …

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 …

Distributed pressure sensors along the drill string from wired drill pipe telemetry, combined
with real-time analysis of the data at the rig, may give valuable information to the drilling …
