Title: Prospektvurderings- og letemodellverktoy for forekomstkartlegging
Inventor: HANTSCHEL THOMAS
IPC: G01V1/28
Filed: 2012-06-08
Abstract: Prospektvurderings- og letemodellkartleggingsverktøy beskrives. For vurdering av potensielle ressurser gir systemeksemplene dynamisk sammenknyttede sannsynlighetskart, transformert i sanntid fra geologiske egenskaper. Inndata geologiske kart eller andre data knyttes dynamisk til resulterende sannsynlighetskart, slik at endringer i inndatakartene automatisk oppdaterer sannsynlighetskartene i sanntid. Brukere kan generere tilpassede risikomatriser som dynamisk forbinder geologiske kart med sannsynlighetskart via et innholdsrikt grensesnittverktøy og slippe kart direkte inn i matrisen. En transformator kan programmatisk konvertere det geologiske domenet til sannsynlighetsdomenet. Brukeren kan navigere inndatakart, velge områder av interesse, og dra-og- slippe geologiske egenskaper direkte inn i en usikkerhetskalkulator og distribusjonsgenerator for usikkerhetsvurdering direkte basert på den geologiske virkeligheten. Et fletteverktøy kan programmatisk forene flere geologiske tolkninger av et prospekt. Fletteverktøyet beregner en enkelt sannsynlighetsverdi for suksess for flere geologiske egenskapsverdier i hver gradnettnode.

Filed: 1993-10-22
Abstract: 2.1. Polyoxymethylene (polyacetal) is an excellent material from which, in particular, rigid articles can be produced in high accuracy. However, since polyoxymethylene is acid-sensitive, the object of the present invention is to provide a polyoxymethylene which has been stabilised towards acids. 2.2. By addition of from 0.01 to 5 parts of an alkali metal salt of a polybasic acid, for example oxalic acid or citric acid, and/or from 0.01 to 5 parts of a polyalkylene glycol, for example polyethylene glycol, and/or from 0.1 to 100 parts of a thermoplastic polyurethane, in each case based on 100 parts of a polyoxymethylene, the latter is stabilised against acid attack, where, in particular, the combination of an alkali metal salt, in particular of an oxalate, with a few parts of a thermoplastic polyurethane is advantageous. The weight loss of a stabilised POM can be less than 3% compared with non-stabilised POM on exposure to acid. 2.3. Areas of application in which the products are exposed to acidic agents, such as irrigation equipment, dishwashers and to the sanitary sector.
