Abstract: A geographically based lottery game is described where prizes are allocated based on the geographic location or residence of the lottery player. The lottery terminal determines the player's residence and sets parameters for the lottery ticket, such as the count of symbols to be picked and the range of the symbols. Prizes are then awarded within the geographic area.

Abstract: Every County Wins is a lottery draw game that involved counties within a particular state within the United States. The percentage of people within that county will determine how many people and how much the prize will be. A person will go to a lottery dealer within. their county and purchase a quick draw Every County Wins Ticket. That ticket will consist of their ticket number and number or letters to identify their county. On the designated draw date a computer generated program will pick a ticket that has been sold in that county. The person with that ticket will be the winner. There will be a draw for every county within the state. People living in larger counties will have more winners. The computer program may pick 2 or 3 winners pending on the population of people in that county.

Abstract: Systems, tools, and methods are presented for processing a plurality of spectral ranges from an electromagnetic radiation that has been interacted with a fluid. Each spectral range within the plurality corresponds to a property of the fluid or a constituent therein. In one instance, a series of spectral analyzers, each including an integrated computational element coupled to an optical transducer, forms a monolithic structure to receive interacted electromagnetic radiation from the fluid. Each spectral analyzer is configured to process one of the plurality of spectral ranges. The series is ordered so spectral ranges are processed progressively from shortest wavelengths to longest wavelengths as interacted electromagnetic radiation propagates therethrough. Other systems, tools, and methods are presented.

Abstract: A computer accepts dead-oil properties of a reservoir fluid sampled from a well. The dead-oil properties are the measured composition of the reservoir fluid after volatile components of the reservoir have substantially vaporized. The computer analyzes the dead-oil properties and a constraint to produce estimated live-oil properties of the reservoir fluid. The live-oil properties are the composition of the reservoir before the volatile components have substantially vaporized. The computer uses the estimated live-oil properties to make a decision regarding the well.

Abstract: A method includes obtaining a plurality of master sensor responses with a master sensor in a set of training fluids and obtaining node sensor responses in the set of training fluids. A linear correlation between a compensated master data set and a node data set is then found for a set of training fluids and generating node sensor responses in a tool parameter space from the compensated master data set on a set of application fluids. A reverse transformation is obtained based on the node sensor responses in a complete set of calibration fluids. The reverse transformation converts each node sensor response from a tool parameter space to the synthetic parameter space, and uses transformed data as inputs of various fluid predictive models to obtain fluid characteristics. The method includes modifying operation parameters of a drilling or a well testing and sampling system according to the fluid characteristics.
