Asymmetric source acoustic LWD for the improved formation shear velocity estimation
Most acoustic logging while drilling (LWD) tools generate a single pure borehole mode (e.g., dipole or quadrupole) to estimate the formation shear velocity. We propose an approach where multipole modes are generated simultaneously and used to obtain a better shear estimation. This approach uses an asymmetric source with arrays of receivers distributed azimuthally around the tool to generate and...
متن کاملAn Experimental Study Of Seismoelectric Signals In Logging While Drilling
Acoustic logging while drilling (LWD) may be complicated because of contamination by waves propagating along the drill collar (the tool waves). In this paper we propose a new method for separating tool waves from the true formation acoustic arrivals in borehole acoustic LWD. The method utilizes the seismoelectric signal induced by the acoustic wave at the fluid-formation boundary. The basis for...
متن کاملSimulation of 3D DC Borehole Resistivity Measurements with a Goal- Oriented hp Finite-Element Method. Part I: Laterolog and LWD
We simulate and study the combined three-dimensional effects on resistivity logging measurements due to dip angle (in deviated wells), different arrangements of three-dimensional electrodes, and anisotropy effects. All results correspond to electrostatic (zero frequency) measurements. Thus, we consider direct current (DC) electrodes. We simulate both laterolog and logging-while-drilling (LWD) m...
متن کاملA new method for Real-Time LWD data compression
Logging while drilling (LWD) is an advanced drilling technology in oil/gas exploration and development, which was developed to increase drilling efficiency and decrease drilling cost. The real-time logging data transmission by the limited transmission bandwidth is a key technology in LWD. Compressing logging data by some algorithm is an evident method to enhance data transmission. This paper in...
متن کاملA Study of Seismoelectric Signals in Measurement While Drilling By Xin Zhan
An LWD acoustic wave can move the excess charge in the electric double layer along the borehole wall to generate a streaming electric field. This thesis is an experimental and theoretical investigation of the electric field induced by the multipole LWD acoustic wave. The main goal of this thesis is to understand the mechanism in the seismoelectric conversion under the LWD geometry and prove the...
