20120138291 | SUBTERRANEAN FORMATION DEFORMATION MONITORING SYSTEMS - Method, devices and systems are provided for measuring deformation in subterranean formations. Such methods include introduction of spaced-apart depth magnetic markers along the longitudinal length of a well bore and measuring the position of each depth marker over time so as to determine deformation of the subterranean formation. In certain embodiments, depth markers comprise rare earth magnets. In further embodiments, orientation of each magnetic bullet is determined over time to determine the change in orientation of each magnetic bullet. Advantages of the methods and devices herein include, but are not limited to, improved accuracy and reliability of deformation measurements and reduced environmental impact due to the avoidance of radioactive markers used by the present invention. | 06-07-2012 |
20120136189 | BUFFERED IONIC LIQUIDS FOR OLEFIN DIMERIZATION - The present invention relates generally to buffered ionic liquids that are very useful for dimerization of olefins, such as isopropene, wherein the buffer is a phosphine or a bismuthine or an arsine or an amine. | 05-31-2012 |
20120078541 | HIGH-PRESSURE QUARTZ CRYSTAL MICROBALANCE - The present invention relates to a high-pressure quartz crystal microbalance sensor that is capable of measuring adsorption and diffusion characteristics of nanoporous materials and thin films at high pressures. | 03-29-2012 |
20120037364 | DELAYED GELLING AGENTS - The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g, in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel. | 02-16-2012 |
20120010452 | HETEROGENEOUS SUPPORTS FOR HOMOGENEOUS CATALYSTS - A method of making a heterogenously supported catalyst useful in dimerization, oligomerization or polymerization is provided in which a catalyst precursor containing a metal and an aromatic group are alkylated onto an oligomeric support having at least one terminal unsaturated group by Friedel Crafts alkylation. | 01-12-2012 |
20110315537 | SELECTIVE TEMPERATURE QUENCH AND ELECTROSTATIC RECOVERY OF BIO-OIL FRACTIONS - A process for quenching, separating and collecting targeted components of a hot pyrolysis product stream from the pyrolysis of biomass is provided. The process utilizes rapid quenching and electrostatic precipitation at a predetermined temperature in order to selectively collect one or more fractions of the hot mixture. | 12-29-2011 |
20110184215 | BIOMASS PYROLYSIS IN REFINERY FEEDSTOCK - This invention relates to biomass pyrolysis through the use of a hot liquid refinery feedstock as a heat transfer medium, preferably a vacuum gas oil feedstock. | 07-28-2011 |
20110182788 | CATALYTIC MOVING BED FILTER - The present invention relates generally to a method for removing contaminants from a fluid stream and chemically upgrading the stream at the same time. More particularly, the invention relates to a catalytic moving bed filter for removing contaminants from a gas or vapor stream and to compositions comprising both moving bed filter materials and one or more catalysts intimately admixed therewith. | 07-28-2011 |
20110071294 | Homogeneous Dimerization Catalysts Based on Vanadium - A series of new bis(imino)pyridine vanadium(III) complexes was synthesized according to formula: | 03-24-2011 |
20110020467 | Inhibition of Biogenic Sulfide Production Via Biocide and Metabolic Inhibitor Combination - Biogenic sulfide production is synergistically inhibited by treating sulfate-reducing bacteria (SRB) with a biocide and a metabolic inhibitor. The biocide directly kills a first portion of the SRB. The metabolic inhibitor inhibits sulfate-reducing growth of a second portion of the SRB without directly killing the second portion of the SRB. The treatment of SRB with both a biocide and a metabolic inhibitor provides effective biogenic sulfide inhibition at significantly lower concentrations than would be required if the biocide or metabolic inhibitor was used alone. | 01-27-2011 |
20110004040 | ORGANOMETALLIC COMPLEXES AS CATALYST PRECURSORS FOR SELECTIVE OLEFIN DIMERIZATION AND PROCESSES THEREFOR - Methods for dimerizing alpha-olefins utilizing immobilized buffered catalysts, wherein the catalytic component is of the formula: | 01-06-2011 |
20110004039 | SELECTIVE OLEFIN DIMERIZATION WITH SUPPORTED METAL COMPLEXES ACTIVATED BY ALKYLALUMINUM COMPOUNDS OR IONIC LIQUIDS - Methods for dimerizing alpha-olefins utilizing immobilized buffered catalysts wherein the catalytic component is of the form: | 01-06-2011 |
20110004036 | HETEROGENEOUS DIMERIZATION OF ALPHA-OLEFINS WITH ACTIVATED METALLOCENE COMPLEXES - Methods for dimerizing alpha-olefins utilizing immobilized buffered catalysts wherein the catalytic component is of the form (ligand) | 01-06-2011 |
20100314115 | SWELLABLE POLYMER WITH CATIONIC SITES - The invention is directed to long lasting crosslinked water-soluble swellable polymers, methods for making same, and their uses. More particularly, the invention relates to a composition comprising expandable polymeric particles having cationic sites as well as labile crosslinkers and stable crosslinkers, said particle mixed with a fluid. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a target zones in the reservoirs and when the heat and/or a suitable pH in the reservoir cause degradation of the labile crosslinker and when the particle expands, the cationic sites in the polymer adsorb to negative sites of the rock in the formation, thus diverting water to lower permeability regions and improving oil recovery. However, many other uses are possible. | 12-16-2010 |
20100314114 | SWELLABLE POLYMER WITH ANIONIC SITES - The invention is directed to stable crosslinked water-soluble swellable polymers and methods for making same. More particularly, the invention relates to a composition comprising expandable polymeric particles having anionic sites and labile crosslinkers and stable crosslinkers, said particle mixed with a fluid and a cationic crosslinker that is capable of further crosslinking the particle on degradation of the labile crosslinker and exposure of the anionic sites so as to form a gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into target zone and when the heat and/or suitable pH of the target zone cause degradation of the labile crosslinker and the particle expands, the cationic crosslinker crosslinks the polymer to form a gel, thus diverting water to lower permeability regions and improving oil recovery. | 12-16-2010 |
