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 method is disclosed for withdrawing particulate spent catalyst particles from a packed, non-fluidized bed of such particles in contact with a liquid medium within a vessel having a withdrawal conduit or pipe which has an inlet that opens within the bottom of the bed and faces generally downwardly so that a first section extends upwardly from the inlet, and a second section extends downwardly, and the spent catalyst particles exits the packed bed through a uniform and continuous flow path opening into a solids recovery vessel whose pressure is controlled to regulate flow of such spent catalyst from the reaction vessel independent of the rate of flow through the withdrawal conduit.

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: An apparatus for testing water quality for subsurface injection that provides for samples of infinite volume to be passed over a membrane filter at a constant pressure. The apparatus uses a positive displacement pump drawing suction on the water source and discharging to a membrane filter. Between the pump discharge and the filter is an oil/water separation vessel to allow for sampling of well production fluids before oil removal if necessary. Fitted to the oil separation vessel is an adjustable pressure regulator, also known as a back pressure regulator, for maintaining constant pressure over the filter. The filter discharge water is collected in a volume calibrated vessel. The vessel is connected to load cells, and a data collection device records weight as a function of time. By measuring the water density, a time/volume curve can be automatically plotted by the data collection device.

Abstract: Disclosed is a gravity settler for separating finely divided solids such as coal fines from a liquid such as a mixture of coal oil and agglomerating agent by agglomeration. A feed slurry comprising finely divided solids and a liquid mixture of product oil and an agglomerating agent is discharged into a specially shaped duct which promotes formation of agglomerated solids while minimizing turbulence in the remainder of the vessel. The agglomerated solids separate from the liquid by gravity and are washed as they leave the settler while the clarified liquid is discharged from the top of the settler. A method for separating suspended solids from a liquid by agglomeration is also disclosed.

In particular, this invention is directed toward polyamino alkenyl or alkyl succinimides which have been modified by treatment with a compound of the formula: ##STR1## wherein W is oxygen or sulfur; X is oxygen, sulfur or R.sub.5 N< wherein R.sub.5 is hydrogen, and alkyl of from 1 to 20 carbon atoms; and R.sub.4 is an alkylene group of from 2 to 5 carbon atoms or an alkylene group of from 2 to 5 carbon atoms substituted with from 1 to 3 alkyl groups of from 1 to 2 carbon atoms each with the proviso that both W and X are not both oxygen. The modified polyamino alkenyl or alkyl succinimides of this invention have been found to possess dispersancy and detergency in lubricating oils. These modified succinimides are also useful as dispersants and detergents in fuels.

Abstract: A method is disclosed for improving the effectiveness of fluid transport in a petroleum reservoir. That method comprises increasing the permeability of a portion of the reservoir by removing liquid water from that portion by evaporating off the liquid water. Preferably, substantially all of the liquid water is removed. In one embodiment, the liquid water is evaporated off by heating the portion to a temperature above the boiling point of water for the ambient pressure of the portion. In another embodiment, the liquid water is evaporated off by injecting into the reservoir a gas (such as heated nitrogen) that is undersaturated with respect to water. In a third embodiment, steam is injected into a well within the portion, and the steam is blown down to vaporize substantially all of the liquid water and to cause the vaporized water to leave the portion. In still another embodiment, superheated steam is injected into the reservoir.

In a preferred embodiment, a portion of the regenerated catalyst of a catalytic cracking process is separated and contacted with the hydrocarbonaceous feed at a temperature and for a time sufficient to strongly bind the basic contaminants in the feed with the separated portion of the acid catalyst. The feed is then passed to the catalytic cracking reactor in a slurry with the separated catalyst, resulting in a desirable conversion increase.
