20080204013 | LOGGING METHOD FOR DETERMINING CHARACTERISTIC OF FLUID IN A DOWNHOLE MEASUREMENT REGION - For use in logging downhole in an earth borehole, a method for determining a characteristic of oil that may be present in a downhole measurement region, includes the following steps: providing a plurality of crude oil samples; determining the viscosities of the crude oil samples; performing test measurements, using a predetermined operating mode, on media including the crude oil samples to obtain test data; applying a test processing procedure to the test data to obtain an output test parameter relating to the test data and the predetermined operating mode; deriving, for the plurality of crude oil samples, a correlation relating the output test parameter to the viscosities of the crude oil samples; performing downhole measurements in the measurement region with a logging device, operated with substantially the predetermined operating mode, to obtain logging data, and applying a measurement processing procedure to the logging data to obtain an output logging parameter; and determining the oil characteristic using the output logging parameter and the correlation. | 08-28-2008 |
20090091320 | Methods and Apparatus for Monitoring a Property of a Formation Fluid - Methods and apparatus for the characterization of formation fluids are disclosed. A downhole tool disposed in a borehole penetrating a subterranean formation obtains a NMR measurement, effects a change in a characteristic of the formation fluid, and obtains another NMR measurement subsequent to the change. Alternatively, the downhole tool effects a radial gradient of a characteristic of the formation and obtains NMR measurements at two or more selected radial distances from the wellbore wall. A parameter representative of the subterranean formation or the formation fluid is further determined from the NMR measurements. | 04-09-2009 |
20090139321 | DETERMINATION OF FORMATION PRESSURE DURING A DRILLING OPERATION - A drilling operation wherein a borehole can be drilled through earth formations with a drill bit at the end of a drill string, using recirculating drilling mud that flows downward through the drill string, exits through the drill bit, and returns to the earth's surface in the annulus between the drill string and the borehole wall, at least a portion of which has a mudcake thereon, and a surface pumping system for pumping the mud to recirculate. Determining true formation pressure, including the following steps: providing a measurement device, having a probe, on the drill string; controlling the mud flow rate to obtain a first measured borehole pressure and measuring, with the probe of the measurement device, as a corresponding first probe pressure, the pressure in the formation adjacent the mudcake; controlling the mud flow rate to obtain a second measured borehole pressure and measuring, with the probe of the measurement device, as a corresponding second probe pressure, the pressure in the formation adjacent the mudcake; and deriving the true formation pressure from the first and second measured borehole pressures and the first and second probe pressures. | 06-04-2009 |
20090143991 | MEASUREMENTS IN A FLUID-CONTAINING EARTH BOREHOLE HAVING A MUDCAKE - A method for determining true formation pressure in formations surrounding a fluid-containing borehole having a mudcake on the surface thereof, including the following steps: at a particular location in the borehole, monitoring the electrokinetic potential across the mudcake; modifying the borehole pressure at the particular location in the borehole; and determining the true formation pressure in the formations surrounding the particular location as being the borehole pressure at which the electrokinetic potential is substantially zero. | 06-04-2009 |
