20130047717 | CORRECTED POROSITY MEASUREMENTS OF UNDERGROUND FORMATIONS - This disclosure relates to methods and apparatuses for determining the porosity of a formation surrounding a borehole. A drilling fluid penetrates a distance into the formation as a function of time. First and second porosity measurements are taken, both at a first time and at a second time. The first porosity measurement is of a type selected to indicate a different porosity measurement in the presence of a gas as compared to the second porosity measurement. The first and second porosity measurements are selected to have substantially the same depth-of-investigation into the formation and are affected approximately proportionally by the gas. | 02-28-2013 |
20120316788 | Formation Testing Planning And Monitoring - An example method comprises collecting formation temperature data along a wellbore extending into a subterranean formation, determining test operating parameter values, performing a wellbore hydraulic simulation of the response of wellbore fluid conditions to the test operating parameter values and the formation temperature data, determining whether the response of wellbore fluid conditions is indicative of one of a well control and a well stability problem, and initiating a test based on the determination whether the response of wellbore fluid conditions is indicative of one of a well control and a well stability problem. | 12-13-2012 |
