Abstract: I have shown that:   (1) Sodic soils, sodic materials, or mixtures of soil and sodic materials, having high SAR values that are detrimental to soil performance and which may also exceed published regulatory threshold levels can, by means of treatment with chelating agents that cause release of calcium and magnesium, be ameliorated so that SAR values fall to non-detrimental levels, without at the same time causing unsuitable increase in salinity (EC).    (2) Permeability of sodic soil markedly improved after treatment with chelating agents. (3) Using the synthetic chelating agent EDTA, the low SAR values of treated sodic materials were persistent.   (4) EDTA added to sodic, alkaline drilling cuttings did not decompose during a test using conditions simulating actual drilling.   (5) Sodic soil treated with EDTA was non-toxic in the Microtox.TM. bioassay.

Abstract: An acoustic logging system with a borehole tool comprising a transmitter assembly and an axially spaced receiver assembly. The transmitter and receiver assemblies are optionally rotatable with respect to each other, depending upon the embodiment of the logging system. The logging system is designed to measure, among other parameters, the velocity (or slowness) and amplitude of shear wave energy induced by the transmitter assembly within formation penetrated by the borehole. These parameters are extracted from full wave acoustic data responses of receiver elements comprising the receiver assembly, and are measured as a function of azimuth around the borehole. These parameters are subsequently used to determine anisotropic properties of the formation, such as the azimuthal direction of formation fracturing with respect to the well borehole. Optional rotation of the transmitter and receiver assemblies minimizes adverse effects of maintaining calibration and balance of multiple transmitters and receivers
