Remote Directional Drilling and Logging While Drilling Operations in the Arctic
IADC/SPE Drilling Conference and Exhibition, 2016Abstract Few locations present as many challenges as drilling in Arctic. It is one of the most hostile environments in the world. It contains some of the most remote locations, the toughest logistics challenges and the largest gaps in infrastructure on the planet.

Logging While Drilling Resistivity Images for Geosteering
SPE Middle East Oil and Gas Show and Conference, 2013Abstract Petroleum Development of Oman (PDO) is undertaking a waterflood development of one of their fields. This project requires drilling horizontal wells in heterogeneous carbonate formations. The water injection wells are planned to be drilled in the lower part of the reservoir which has high porosity and water saturation of minimum ...

The crucial element in logging that has so far been covered up, is the wellbore and the drilling process that creates it. Although it is beyond the scope of this volume to discuss drilling, there are several aspects that merit mention in their relationship to logging.

Logging While Drilling Via Autonomous Sonde
Proceedings, 2014We present a method of geophysical logging while tripping drill rods to produce logs similar to wireline logs. The process is autinmous in that it does not require any significant changes by the driller and does not requie any modifications to the drill rig.

SPE Annual Technical Conference and Exhibition, 2006
Abstract A new while-drilling propagation resistivity system with a novel architecture has been developed that greatly reduces lost-in-hole exposure and provides increased operational efficiency and flexibility. The downhole electronics, antennas, and battery are mounted in a retrievable and reseatable tool unit with a 1.75-in.

Application Status of the Technology of Logging While Drilling
Advanced Materials Research, 2014The data of Logging While Drilling is used for Geosteering and evaluation of layers. Compared with traditional logging, LWD has its own advantages, real-time, security, and it could obtain original information of the destination formation.With the rapid development of logging tools design, LWD tools have a large improvement, and various tools used for ...

Temperature Correction in NMR Logging While Drilling
SPE Oil and Gas India Conference and Exhibition, 2017Abstract The formation temperature affects numerous logging measurements including nuclear magnetic resonance (NMR) data. Obtaining NMR porosity requires the multiplication of the raw NMR signal by a factor that includes the temperature in the sensitive volume.

Nuclear Logging-While-Drilling Measurement: An Assessment
Proceedings of Middle East Oil Show and Conference, 1997Abstract The state-of-the-art in nuclear logging-while-drilling measurements is discussed. Recent improvements in design and interpretation to address the difficulties encountered by these measurements in the dynamic borehole environment that exists are described. Examples of evaluation of the measurement from field data are given.

A deep resistivity logging-while-drilling device for proactive geosteering
The Leading Edge, 2003Reading deep into the formation has always been an ojective of formation evaluation. Historically, when drilling vertical wells, reading deep involved imaging seismic reflectors with intermediate vertical seismic profile (VSP) runs to “look ahead” and to assess invasion or borehole damage with deep-resistivity devices.
