Horizontal Wells 2021, 2021
Summary Drilling process geological monitoring becomes more critical due to horizontal drilling percentage increase over the last two decades. That results in a growth of LWD operative interpretation demand and makes necessary to provide the formation evaluation data as soon as possible.

Applications for an LWD Formation Tester
SPE/IADC Drilling Conference, 1999Abstract After a well or a well interval has been drilled, zones of interest are often tested to determine various formation properties such as permeability, fluid type, fluid quality, formation pressure, and formation pressure gradient. Currently wireline formation testers are most commonly used to perform this testing. However, the use

Proceedings of SPE Annual Technical Conference and Exhibition, 2002
Abstract The need for a caliper measurement for logging-while-drilling (LWD) has prompted developments in several measurement domains. Hole size measurements are mainly derived from ultrasonic and electrical devices. However, both techniques have significant limitations.

Reliable LWD Calliper Measurements
SPE Offshore Europe Oil and Gas Conference and Exhibition, 2011Abstract While perhaps not so glamorous as other measurements, calliper measurements are nonetheless an essential component of formation evaluation. Not only do we need to know the hole size for environmental corrections to other logs, such as nuclear measurements and sonic dispersion analysis, but an accurate indication of hole shape ...

Advances in LWD Nuclear Magnetic Resonance
SPE Annual Technical Conference and Exhibition, 2001Abstract A second generation of LWD Nuclear Magnetic Resonance (NMR) tools has been developed and commercialized. These MRI-LWD* (Magnetic Resonance Image - Logging While Drilling) tools extend the technology by providing key improvements in data quality and operational efficiency.
