3D images of a wellbore generated in real time support drilling engineers to monitor wellbore profiles. Including the time as 4th dimension, 4D images can be used to analyze the evolution of the wellbore geometry as well as to support the drilling en

Characteristics of formations usually cause changes in the drilling parameters such as weight on bit and drill string rotational speed as well as drill string dynamic behavior. When the drill bit breaks up formations, some of the energy dedicated to

An ultrasonic sensor has been developed for MWD (measurement while drilling) and LWD (logging while drilling) applications that perform real time borehole caliper measurements and also wellbore stability monitoring. The caliper determines the oval sh

Abstract Vibrations are known as destructive loads and thus are leading to downhole fatigue failures, severe bottom hole assembly and bit wear and may cause wellbore instabilities. Downhole measurement of vibrations, however, can provide valuable inf

Abstract Drilling programs continue to push into new and more complicated environments. As a result, accurate measurement and analysis of drilling data in real time are becoming more critical by means of minimizing failure costs. The measurement of a

Vibrations are caused by bit and drill string interaction with formations under certain drilling conditions. They are affected by different parameters such as weight on bit, rotary speed, mud properties, BHA and bit design as well as by the mechanica

The measurement of actual wellbore shape in real-time can be considered as one of the key components to detect problems such as borehole instability. Abnormal wellbore shape will allow drawing conclusions on the stress field and the impact on other s

A drill bit creates a hole in subsurface formations by applying weight on bit and rotary speed. The bit is the first segment of the bottom hole assembly (BHA) and the drill string which contacts formation. Today it is possible to monitor drilling par

Since vibration and shock loads are always known as a destructive loads while drilling a borehole and reason for tool failure, more detailed studies of vibration and dynamic behavior of drill string and bottom hole assembly to prevent any time lost a
