Drilling solutions for geological services

Digital Mud Logging Services

Nabors Geologists by using Quantitative Fluoresce Technique II Technology was able to pin point oil in two different zones and increased oil production by 400 barrels per day in sands that were considered wet. During analysis of digital mud logging (DML) data on a client’s well, our experienced geologists noticed trends from wells in the field toward abnormal gas levels and a change of penetration rate. They immediately notified the operator, who decided to stop drilling and pull the drillstring, to discover a dull drill bit. Eliminating the dull drill bit saved the customer approximately nine hours of slow drilling time and optimized rate of penetration.

Nabors Geological Services provides the broadest range of geological evaluation services to help you safely optimize field exploration, wellbore placement and development.

About NDS Geological ServicesNabors Geological Services provides high-quality data and expert interpretation of all wellsite geological data—including measurement while drilling (MWD), logging while drilling (LWD) and pressure while drilling (PWD), directional and petrophysical data, electric log data, surface logging, and drilling parameters—to provide a comprehensive wellbore evaluation. Backed by an experienced team of geologists and wellsite applications engineers, customers receive advanced formation evaluation for better decision making to efficiently and accurately place the wellbore.

In addition. Enables drilling crews to optimize the drilling process, recognize potential formation problems before they affectdrillingperformance,andmaintaina safe rig operating environment.

• myWells.com® Portal transmits real-time integrated wellsite data and provides a one-stop location for viewing all of your wellsite information, including operator and contractor daily report information to sophisticated real-time drilling instrumentation logs and daily mud logs. Whether your well was logged three weeks ago or three months ago, all your data is equally accessible.

All logging geologists are trained to analyze and interpret real-time data to identify and mitigate well control events.

• End of Well Reporting provides detailed well data and supports management of future wells

• Monitor drilling parameters to identify drillinginefficiency

• Prevention of stuck pipe through monitoring torque and drag to inadequate hole cleaning that can cause wellbore caving or damage

• Remote Loggingisacosteffectivealternative to traditional manned surface logging. Powered by RigWatch® and myWells.com® Portal, it allows expert geologists to monitor multiple wells and support critical decisions that help drill wellsmoreefficiently
