Title: Steam distribution and production of hydrocarbons in a horizontal well
Inventor: CHAN KAI
IPC: E21B43/24
Filed: 1997-11-18
Abstract: A system for enhancing steam distribution in a thermal stimulation phase, and for reducing the production of particulate matter with hydrocarbon fluids in a production phase, has a base pipe with a limited number of spaced-apart holes. The spaced-apart holes are sized and located so that steam is uniformly distributed in the reservoir. A collar is disposed around each hole to deflect the steam into an annulus between the base pipe and a wire-wrap screen section to avoid erosion and deterioration of the wire-wrap screen, which is required in the production phase. Mobilized hydrocarbon fluids flow to the wire-wrap screen section, which acts to filter particulate matter so that the production of particulate matter with hydrocarbon fluid is limited. The open area in the base pipe is significantly reduced, as compared with conventional methods, so that at the design injection rates, the pressure drop through the spaced-apart holes is larger than the pressure drop along the base pipe. During hydrocarbon fluid production, the pressure drop from the reservoir to the spaced-apart holes is low due to the presence of the wire-wrap screens. The open area in the base pipe while significantly reduced at the design production rates, as compared with conventional methods, should not unduly limit production rates.

Title: Improved fat-splitting process
Inventor: ANDERSON KEVIN W
IPC: C12P7/64
Filed: 1996-05-28
Abstract: Carboxylic acids and glycerine are made by a continuous splitting process which involves the formation of a presplitting mixture by separately adding the glyceride, and effective lipase in an amount sufficient to produce partial splitting of the glyceride, and water. The water used in the formation of the presplitting mixture is water that has been separated from the glycerine-water effluent stream from the pressure splitter and recycled. The next step involves the pressure splitting which entails mixing the partially split glyceride from the presplitter with water and heating under conditions of temperature and pressure effective to substantially complete the splitting of the glyceride into component fatty acids and a glycerine-water stream. The water is then separated from the glycerine-water stream and the water is recycled to the presplitter.

Filed: 1998-08-20
Abstract: A communications network has a plurality of nodes interconnected by an optical transmission medium. The transmission medium is capable of a carrying a plurality of wavelengths organized into bands. A filter at each node for drops a band associated therewith and passively forwards other bands through the transmission medium. A device is provided at each node for adding a band to the transmission medium. Communication can be established directly between a pair of nodes in the network sharing a common band without the active intervention of any intervening node. This allows the network to be protocol independent. Also, the low losses incurred by the passive filters permit relatively long path lengths without optical amplification.

The calibration body is maintained in contact with the optical window during a calibration sequence using an adhesive, an endcap, shrink wrap material, or other suitable means. After the system is calibrated, the calibration body is removed and discarded and the investigation is begun. Once the investigation is completed, the sheath containing the optical window is removed, if present, and discarded.
