Abstract:
A communication method for retrieving stored data from an MWD tool, through an antenna used for conventional EM data telemetry. The method comprises establishing electrical contact between a surface transceiver and an EM data telemetry antenna upon retrieval to the surface. The MWD tool then transfers data through the antenna, the data being received by the surface transceiver. Also provided is an electrical isolation connector subassembly comprising an electrically insulative coating to electrically isolate the splitsub components, thereby forming the antenna for data transfer and EM data telemetry.
Abstract:
A mixture of saturated and unsaturated carboxylic acids are hydrogenated with an effective amount of a hydrogenation catalyst and in the presence of an effective amount of an adsorbent to produce a hydrogenated product having less than about 200 ppm of oxygenated by-products and an iodine value of less than 10.
Abstract:
A process for making a soften or fluid personal cleansing composition comprising: (a) providing a solid personal cleansing stock consisting essentially of an acyl isethionate; (b) heating the solid personal cleansing stock using microwave energy to form a softened or molten stock personal cleansing component; (c) introducing the softened or molten stock personal cleansing into a mixing apparatus; (d) introducing a personal cleansing adjuvant into the mixing apparatus; and (e) mixing the softened or molten personal cleansing stock and adjuvant in the mixing apparatus to form a softened or fluid personal cleansing composition.
