Determination Of Virgin Formation Temperature
US Patent:
6905241, Jun 14, 2005
Filed:
Mar 13, 2003
Appl. No.:
10/249068
Inventors:
Alexander Zazovsky - Houston TX, US
Sammy S. Haddad - Mandeville LA, US

Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
G01K001/16, G01K003/04, E21B047/00, G01V009/00
US Classification:
374134, 374 25, 374102, 7315201, 702 11, 324324, 324332
Abstract:
A method for determining virgin formation temperature of earth formations surrounding a borehole is provided. The time duration of drilling fluid circulation and the time after cessation of drilling fluid circulation at the borehole depth regions of interest are tracked. At a particular borehole depth region of interest, fluid flows from the formations into a device in the borehole, and the temperature of the fluid as a function of time with respect to initiation of fluid flow is measured. The thermal history of formations surrounding the particular borehole depth region is modeled for a cooling phase during drilling fluid circulation, a temperature build-up phase after cessation of drilling fluid circulation, and a formation fluid flow phase after initiation of fluid flow. The model and temperature measurements are used to determine a trend of temperature evolution and the virgin formation temperature by extrapolation from the trend.

Assignee:
Schlumberger Technology Corporation - Sugar Land TX
International Classification:
E21B 49/00
US Classification:
7315205
Abstract:
A method is disclosed for determining viscosity and density of fluid from formations surrounding an earth borehole, including the following steps: (a) suspending a formation testing device in the borehole; (b) drawing formation fluid into the device; (c) causing the fluid to flow in a flow line under a first set of conditions; (d) causing the fluid to flow in the flow line under a second set of conditions; (e) measuring a first fluid pressure differential in the flow line during fluid flow under the first set of conditions, and measuring a second pressure differential in the flow line during fluid flow under the second set of conditions; and (f) determining density and viscosity of the fluid as a function of the first and second measured pressure differentials.

International Classification:
E21B 47/00
US Classification:
7315239, 73 6456, 7315223, 7315224, 7315225, 7386323, 16625001
Abstract:
A method and apparatus for testing formations surrounding an earth borehole. The method includes the following steps: providing a tool movable through the borehole; providing a flow line in the tool; establishing fluid communication between the formations and the flow line of the tool; and providing a sand trap in communication with the flow line of the tool for trapping sand flowing with fluid from the formations.
Method Of Predicting Formation Temperature
US Patent:
2003010, Jun 5, 2003
Filed:
Nov 30, 2001
Appl. No.:
10/006612

International Classification:
G01K013/00, G01K001/14
US Classification:
374/136000, 374/141000
Abstract:
The present invention discloses a method of calculating a static formation temperature in a reservoir penetrated by a wellbore. One embodiment of the present invention comprises estimating the static formation temperature and calculating a formation fluid temperature at the wellbore, the calculation based, in part, on the estimated static formation temperature. The temperature of a sample of formation fluid at the wellbore is measured. The calculated formation fluid temperature at the wellbore is compared with the measured temperature of the sample of formation fluid. The static formation temperature is predicted by altering the estimate of the static formation temperature until an error between the calculated formation fluid temperature at the wellbore and the measured fluid formation temperature is minimized.
