The TerraFusion tool offers the best insights for geosteering, borehole quality and geological structures as well as revealing fracture networks in all mud types. Available in two sizes (4.75” and 6.75”), the TerraFusion is a latest generation Azimuthal Gamma Ray and Ultrasonic imaging LWD tool incorporated into a single collar.

Gamma Ray tools produce a measurement of the naturally occurring gamma radiation found in rock formations. The Gamma Log produced by these Gamma Ray Sensors is most commonly used for Geosteering, correlation with existing open hole logs, identifying low and high radiation lithologies and depth correlation.

High-Pressure, High-Temperature LWD Obtain high resolution gamma ray, neutron-density, bore and annular pressure, and resistivity logs while drilling in the world’s hottest wells. Measure neutron porosity and formation density while drilling

Reduce uncertainty with the Compass Azimuthal Gamma Module and easily distinguish between formation layers with low gamma ray content. This highly accurate azimuthal gamma ray LWD tool measures gamma rays from 4 quadrants in the formations adjacent to the wellbore and is ideal for Gamma Ray imaging in real-time and recorded mode.

gamma ray images. The HAGR tool contains a ring of Geiger-Müller tube detectors that acquire azimuthal gamma ray data in both rotating and sliding drilling modes. Furthermore, the HAGR sensor can be placed in different positions in the LWD string to obtain azimuthal gamma ray information near the bit. HAGR azimuthal gamma ray sensors are ...

Our suite of LWD technologies provides a wide array of solutions to target your most complex operations. A probe-based, API-calibrated detects naturally occurring gamma radiation from the formation. At-bit collar-based tools and standard probe-based sensors are API calibrated and provide radial gamma ray and precision inclination.

2023年4月1日 · In this paper, based on the spatial distribution law of gamma rays and The Monte Carlo N-particle code (MCNP)-driven spatial sensitivity function, a 3D fast forward method of gamma ray LWD is proposed.

2012年11月17日 · Based on the attenuation law of gamma-ray (GR) in formation, this paper deduces a fast forward algorithm for LWD GR response in different strata models with the integral method, which overcomes the difficulty that the Monte Carlo algorithm is hard to be used for real-time forward calculation at present.

2024年11月1日 · This study investigates the applicability of deep learning with transfer learning, to tackle this prominent challenges. Grounded in a practical fusion of engineering and geology, we address a specific issue: the depth-lagged measurements of the Logging While Drilling (LWD) tool's Gamma Ray detector, owing to its position meters behind the drill ...

2015年7月18日 · A low-cost spectral gamma ray measurement has recently been developed for use in logging-whiledrilling (LWD) applications. Applications range from geosteering and bed boundary detection to formation evaluation for clay typing and for empirical correlations to estimate total organic carbon (TOC).
