... Abstract Despite advances in Measurement-While-Drilling / Logging-While-Drilling (MWD/LWD) technologies, the oil & gas industry has until recently lacked viable technologies and tools to measure wellbore geometry in large hole sizes (>12-1/4″) while drilling and subsequently the ability...

... heavily on the expert oversight monitoring of incoming logging-while-drilling (LWD) data and continuous manual updating of geologic interpretations to identify key points in a well where directional decisions need be made. The labor-intensive nature of this work means that a remote supervisor is often...

... for optimal well placement of the geothermal injection/production doublet. The real-time data was correlated to reservoir model to design and implement a reliable well trajectory and to increase reservoir exposure. Alongside LWD (logging while drilling), advanced near real-time cuttings analysis utilizing...

... Abstract Decision making to optimize the drilling operation is based on a variety of factors, among them real-time interpretation of drilled lithology. Since logging while drilling (LWD) tools are placed some meters above the bit, mechanical drilling parameters are the earliest indicators...

... Abstract The development of measurement while drilling (MWD) and logging while drilling (LWD) tools for highly efficient directional drilling operations warrants the development of extended control and better sensing capabilities in the drilling tools. A direct consequence of these requirements...

... Abstract In addition to formation evaluation, logging-while-drilling (LWD) measurements can also be used as a real-time solution to issues that arise during drilling. For example, LWD measurements can be interpreted to help determine if increasing mud weight is useful or if the rate...

This placement ensures proper installation of the activation ball in the underreamer and connectivity of the RSS and MWD/LWD so that directional work can be executed. However, this placement also leaves...

...) of 45-60°. These design requirements impose a significant challenge to the efficient execution of a Wheatstone well. Traditional “ahead-of-the-bit” logging-while-drilling (LWD) solutions are capable of detecting resistivity fluctuations up to 1m in front of the drill bit. This, however, was considered...
