LWD acquires formation evaluation and wellbore data in real time while the bit is cutting rock. Sensors housed in drill collars measure gamma ray, resistivity, density, neutron porosity, sonic, NMR, ...

Real-time detection and estimation of overpressured formations is now possible using sonic and other logging-while-drilling (LWD) measurements. Data acquired from an overpressured formation in the ...

Well logging chronicles the depths, subsurface formations and events encountered while drilling. Well logs can include visual observations or be made by instruments lowered into the well during ...

HOUSTON – Halliburton has introduced 3D reservoir mapping, a new logging-while-drilling (LWD) capability that provides a detailed representation of subsurface structures to improve well placement in ...

Schlumberger introduced its new-generation Scope while-drilling services that, according to the press release, dramatically improve drilling performance and well placement, leading to increased ...

Measurement while drilling (MWD) systems monitor wellbore position, drill bit performance, and drill string orientation. Instruments in a module in the steering tool of the drill string transmit ...

Comprehensive new logging services focus on enhancing subsurface insight, optimizing drilling performance and ensuring consistent well delivery, to help operators minimize cost and risk while ...

Real-time streaming well data monitors drilling performance and aids drilling decisions using web-based drilling models to calculate and predict drilling parameters. These models improve rate of ...

Well logging is the practice of recording and analyzing various kinds of data about the rock formations around a borehole during or after drilling. Also called borehole logging, this activity aims to ...

Halliburton Co. has introduced 3D reservoir mapping, a logging-while-drilling (LWD) capability that is said to provide a detailed representation of subsurface structures to improve well placement in ...

Houston oilfield service company Halliburton has gone 3D with new technology that improves how geologists analyze a formation's properties during the drilling process. The company's new 3D reservoir ...
