Geosteering Horizontal Wells using Resistivity Anisotropy Obtained in an Offset Vertical Well
Proceedings of SPE Latin American and Caribbean Petroleum Engineering Conference, 2003Abstract Traditional resistivity logging instruments, when logged in vertical wells through horizontal beds, evaluate the horizontal resistivity (Rh) of the formation. The response of the laterolog tool in the same environment, however, is also sensitive to the vertical resistivity component (Rv).

Resistance resonance in coupled potential wells
Physical Review Letters, 1990A new resistance resonance effect based on the quantum-mechanical delocalization of electrons in a symmetric-double-well potential is presented. We show that changing the symmetry of the potential profile gives rise to a resistance peak if the transport properties of the two wells are different.

Proxy Capacitance-Resistance Modeling for Well Production Forecasts in Case of Well Treatments
SPE Journal, 2022Summary We disclose a new-age field-scale production forecast model that handles complex treatment of wellbores during their life cycle. Predictive production models have been an object of increased interest and research for a long time due to the need for a fast tool for forecasting production rates or choosing an optimal field ...

Resistivity Measurements And Modeling In The Vicinity Of A Trench Well
10th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1997On North Andros Island, Bahamas, an extensive array of trench wells has been dug to collect fresh water from the surface (unconfined) aquifer for export to Nassau. There is concern that salt water will upcone below the trenches if water is withdrawn too rapidly.

Why is Anti-Microbial Resistance a Veterinary Problem As Well?
Journal of Veterinary Medicine Series B, 2001Resistance to anti‐microbial agents has become one of the main issues in public health strategies world‐wide. Much attention has been paid to the emergence of pathogenic micro‐organisms such as enterococci orSalmonellathat have developed resistance mechanisms that render them almost untreatable with current antibiotics.

uRANIA: A micro-Resistive WELL for neutron detection
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2022The goal of the uRANIA-V (μ-RWELL Advanced Neutron Imaging Apparatus) project is the development of an innovative thermal neutron detector based on μ-RWELL technology. The μ-RWELL is a reliable, cost effective, easily scalable, resistive MPGD. A thin layer of 10B4C on the cathode surface allows the thermal neutron conversion into products easily ...

A New Resistivity Logging Method in Production Well
Advanced Materials Research, 2012This paper presents a new method for resistivity logging in production well. Based on electromagnetic theory, an electromagnetic response model is established for multi-cylindrical-layer, and the general expressions for through casing electromagnetic logging are deduced.

NEW RESULTS IN RESISTIVITY WELL LOGGING*
Geophysical Prospecting, 1975AbstractTwo independent theoretical analyses show that, spacing for spacing, the two‐electrode normal device investigates deeper than the seven‐electrode focused Laterolog 7. The first analysis, published earlier, compares the radii of investigation of the different sondes from the portion of the ground that contributes maximum to, or fifty percent of,

Lineshape of the resistance resonance in coupled quantum wells
Superlattices and Microstructures, 1992Abstract Details of the resistance resonance effect in strongly coupled quantum wells are measured over a wide range of densities. The shape of the resistance resonance curve is described by a simple model. The fit provides a new method for determination of the coupling energy between the two quantum wells.
