Abstract: A LCD display is driven by certain elements to indicate the responses of a geophone to various tests as a waveform. Waveforms are displayed for an impulse tests, wherein a current pulse is applied to the geophone and the response is displayed, and for a tap test, wherein the top of a geophone is tapped and the first break of the resulting displayed waveform indicates the polarity of the geophone connections. Response to a resistance test is provided by a level indicator. The waveform on the display may be examined with reference to a comparitor indicative of a proper response, and the operational or disfunctional condition of the geophone thereby determined.

Abstract: A portion of a formation is heated by introducing heated water into a borehole within the formation and imposing an oscillatory motion onto the heated water. The heated water can be introduced into the borehole by injecting water into the borehole and heating in situ the injected water, or by injecting heated water into the borehole, or by heating in situ water already present within the borehole. In one embodiment, the heated water is maintained as a liquid phase at a temperature of at least 180.degree. F. within the borehole by using electrically driven paddles to impose upon the heated water oscillatory motion having a frequency of from 1 to 100 hertz.

Abstract: The present invention is a process to recover metals from refractory ores. It involves the chlorination of an ore concentrate in the presence of solid salt at a temperature between 300.degree. and 650.degree. C. Thereafter, an oxidation step can be used to convert iron chloride to iron oxide. Subsequent separation steps remove the salt, gangue, and iron oxides. Separate pathways are described for precious and base metal recovery.

Abstract: A fluid catalytic cracking unit equipped with multiple feed injection points along the length of the riser is operated such that all of the fresh feed is charged to one of different feed injection points, depending on the ratio of light distillate (gasoline) to middle distillate (light catalytic gas oil) that is desired in the product slate. When all of the fresh feed is charged to one of the upper injection points in the riser in order to increase middle distillate yield, the unconverted slurry oil (650.degree. F.+material) can be recycled to a location below the injection point of the fresh feed so as to increase conversion to middle distillate while lowering the activity of the catalyst (via coke deposition) for single pass conversion of the fresh feed. Steam in excess of levels typically employed for dispersion is used at the bottom of the riser to lift the regenerated catalyst up to the feed injection points.

Abstract: A method for providing improved measurement of oil, water, and gas flow rates in producing wells using thru-tubing wireline inflatable and retrievable packers or plugs to systematically isolate producing zones within a wellbore.
