Novel systems such as the wired-pipe or networked drillstring telemetry system have
allowed broadband communication with downhole tools in various operating areas around …

Through bit logging is a method for data acquisition using the drill string and bit as a conduit
to the well bore. Two case studies are presented demonstrating the unique capabilities of …

Depth is arguably the most important measurement made during data acquisition. It is the
index used to associate multiple data types both within a well and also amongst multiple …

Abstract Coiled Tubing Depth Measurement has become more critical with the advent of
new coiled tubing services, such as logging, drilling, perforating and zonal isolation. For …

This article, written by Senior Technology Editor Dennis Denney, contains highlights of
paper SPE 150422,'Early Symptom Detection Based on Real-Time Evaluation of Downhole …

Stuck pipe is one of the main problems in drilling oil and gas reservoirs. It usually occurs in
high pressure wells and leads to tremendous delays and costs in Iran, every year. Even if …

During drilling operations poor hole cleaning may result in low drilling efficiency, stuck pipe,
problems with well control or even a loss of the wellbore. In this paper a method for warning …

Currently, well control events are almost exclusively detected by using surface
measurements. Measuring a volume increase in the'closed loop'mud circulation system; a …

Abstract The Halliburton Free Point tool is a game-changing technology in the determination
of the free point/stuck point in support of drilling and well abandonment operations. The …

Recognizing abnormal fluid influx is the first and most important step for well control safety.
However, due to the complexity of the wellbore fluid mechanism, uncertainty of the formation …
