Polymer production at supercritical conditions

Abstract: This invention relates to a process to polymerize olefins comprising contacting, in a polymerization system, olefins having three or more carbon atoms with a catalyst compound, activator, optionally comonomer, and optionally diluent or solvent, at a temperature above the cloud point temperature of the polymerization system and a pressure no lower than lOMPa below the cloud point pressure of the polymerization system, where the polymerization system comprises any comonomer present, any diluent or solvent present, the polymer product, where the olefins having three or more carbon atoms are present at 40 weight % or more, wherein the catalyst compound is a bridged metallocene based on indenyl groups.

Method of drilling and producing hydrocarbons from subsurface formations

Abstract: A method associated with the production of hydrocarbons. In one embodiment, method for drilling a well is described. The method includes performing drilling operations at one or more wells to a subsurface location in a field to provide fluid flow paths for hydrocarbons to a production facility. The drilling is performed by (i) obtaining mechanical specific energy (MSE) data and other measured data during the drilling operations; (ii) using the obtained MSE data and other measured data to determine the existence of at least one limiter; (iii) obtaining and examining lithology data for the well; (iv) identifying a primary limiter of the at least one limiter based on the lithology data; and (v) adjusting drilling operations to mitigate at least one of the at least limiter.

Lithium Ordering in Li x Ti S 2

Abstract: A new electrochemical measurement applied to the Li/Ti${\mathrm{S}}_{2}$ cell reveals subtle changes in slope on the voltage-composition relationship. These anomalies occur at compositions where ordered structures among intercalated lithium are predicted from lattice-gas theories. ${\mathrm{Li}}_{x}\mathrm{Ti}{\mathrm{S}}_{2}$ appears to be a nearly ideal model for the study of composition- and temperature-dependent properties of the two-dimensional lattice gas.
