Logging while drilling (LWD) is a technique of conveying well logging tools into the well borehole downhole as part of the bottom hole assembly (BHA).

Available in two sizes (4.75” and 6.75”), the LithoFusion is a latest generation Azimuthal Density and Porosity LWD tool incorporated into a single collar. Designed for both oil-base and water-base muds, it enables geosteering and formation evaluation while …

Jul 15, 2024 · Weatherford experts suggested the hexa-combo logging-while-drilling (LWD) bottomhole assembly (BHA), with the distance-to-bed inversion combined with the azimuthal density images, to help locate the target zone boundaries and formation dipping.

A bottom hole assembly (BHA) is a component of a drilling rig. It is the lowest part of the drill string, extending from the bit to the drill pipe. The assembly can consist of drill collars, subs such as stabilisers, reamers, shocks, hole-openers, and the bit sub and bit. [1]

In this paper, we present a methodology for determining lithological difference at the bottom of the well during drilling operations. Our approach is based on the analysis of mechanical parameters...

Baker Hughes LithoTrak™ advanced LWD porosity service provides accurate, reliable and versatile nuclear porosity and and formation density logs using an innovative downhole

Weatherford experts suggested the hexa-combo logging-while-drilling (LWD) bottomhole assembly (BHA), with the distance-to-bed inversion combined with the azimuthal density images, to help locate the target zone boundaries and formation dipping.

The PNG used in the EcoScope service enables generating neutrons on demand and eliminates the need for an AmBe chemical source. In addition to resistivity, neutron porosity, and azimuthal gamma ray and density measurements, the multifunction LWD service evaluates elemental spectroscopy and sigma.

The custom-designed BHA included a powerful suite of LWD services. Power generated for entire BHA, enabling LWD data acquisition ConocoPhillips moved forward with the slimhole BHA for the 6-in lateral section and was able to acquire all the required data in high resolution.

Acquire high-quality, real-time formation evaluation data while drilling throughout the curve and lateral to enable accurate geosteering. Weatherford deployed a bottomhole assembly (BHA) including a triple-combo logging-while-drilling (LWD) package, a HyperLineTM 250 drilling motor, and a HELTM MWD system.
