Deviated, horizontal, and multilateral wells are drilled to increase the contact area between
the well path and the reservoir and as a result, the well productivity will be increased …

An experimental rig for near-bit force measurement and drillstring acoustic transmission of
bottom-hole assembly (BHA) is designed and implemented to investigate downhole …

Simulation techniques are increasingly becoming popular in recent years as a way of
simulating oil drilling processes. Among them, directional drilling is a specific method that …

Measurement while drilling (MWD) technology is important for obtaining downhole
parameters. As an essential parameter in drilling engineering, lateral force provides a …

Directional drilling is controlling the inclination and azimuth of a wellbore to reach a
predetermined underground target and is a method used widely nowadays. There are …

This paper presents a new method to accurately determine the strata while drilling. We
developed an original prototype of instrumented drilling system, with it the measurement …
