n: Schlumberger wireline tool that measures phase shift and attenuation of a 1100 MHz wave. Used for Hydrocarbon identification independent of formation water salinity, thin bed detection, Hydrocarbon saturation and mobility and to evaluate invaded zones.

n: Schlumberger wireline tool designed to acquire multilevel triaxial seismic data in cased holes. Provides high quality seismic images in relatively close proximity to the wellbore.

n: Schlumberger wireline tool that digitizes compressional, shear, and Stoneley waveforms and is designed to minimize the discrepancies between sonic and seismic data. Used for porosity evaluation, shear seismic correlation, thin bed detection, fracture pred

n: This schlumberger module provides direct measurements of wellbore fluid resistivity and temperature, also cable tension below the toolstring head. Useful to run in poor hole condition;should allow differentiation of differential sticking and keyseat stic

n: Schlumberger wireline tool that provides a measure of casing to cement and cement to formation cement bond.

n: Schlumberger wireline tool that determines cement distribution and quality from sonic response. Also measures casing thickness and so can detect damage or corrosion.

n: Schlumberger wireline tool that can recover up 90 core samples per trip. An explosive charge fires a hollow bullet into the formation, which is attached to the tool with wires. When the tool is moved, the bullet and sample are pulled out of the formation.

n: Schlumberger/Anadrill LWD tool which combines density and neutron porosity in one tool. Useful for gas detection, porosity evaluation, and lithology determination.

n: Schlumberger/Anadrill LWD tool that measures resistivity at two depths of investigation. Also measures spectral gamma ray to give relative proportion of potassium, thorium, and uranium.

n: Schlumberger/Anadrill LWD tool that bombards the formation with fast neutron. Detectors measure the slowed neutrons that are bounced back by Hydrogen atoms. Used to deduce porosity, lithology, clay analysis, and gas detection.
