摘要： Methods and apparatus facilitating radial profiling of shear slowness are disclosed. According to some aspects of the invention, acoustic tool bias is accounted for in the calculation of radial profiles. According so some aspects, acoustic tool bias is accounted for by replacing acoustic tool structure with a resonance-impedance model. The resonance-impedance modeling according to principles of the present invention is applicable to vertical, deviated, and horizontal boreholes.

摘要： A logging system has a sonde in a borehole, which transmits sonic waves with one or more dipole sources to optimally excite dipole flexural mode sonic waves in the borehole. The system first determines the Airy frequency of the borehole. Then, the dipole sources are fired at a dipole firing frequency selected based on the Airy frequency.

摘要： Disclosed is an efficient and economical method for the preparation of N-glycolyl neuraminic acid in a high purity from an inexpensive abundant source material. The method comprises dispersing body tissues of an echinodermatous marine animal Cucumaria echinata in an aqueous medium, preferably, using a dry powder of the tissues prepared in advance, in which the tissues are proteolytically decomposed to isolate N-glycolyl neuraminic acid in the form of an aqueous solution containing polypeptides as a by-product, followed by separation of N-glycolyl neuraminic acid from the aqueous solution by removing the polypeptides and purification of the compound in a process utilizing an ion-exchange treatments.

摘要： Disclosed is an economical method for the preparation of chondroitin sulfates A and C useful as an effective ingredient of medicaments from fish scales as a waste material discharged from fishery in large quantities. Fish scales are enzymatically decomposed in an aqueous medium in the presence of a protease to isolate the chondroitin sulfate compounds and by-product polypeptides followed by removal of the by-product polypeptides from the aqueous solution by a cation-exchange treatment and then the aqueous solution of the chondroitin sulfate compounds is subjected to fractional precipitation by the addition of ethyl alcohol as the precipitant.

摘要： A method for in-situ calibrating acoustic receivers while the tool is in an open or cased borehole or during a logging run in a borehole. The method and system facilitate calibrating the acoustic receivers while they are mounted to a downhole acoustic tool. Calibrating the acoustic receivers in situ provides more accurate results than previously available. The method and system provide separate compensation factors for the acoustic receivers at different frequencies and for different transmission sources. The separate compensation factors facilitate more accurate signal acquisition over a wider range of conditions.
