    摘要： A method of estimating a property of interest downhole according to one aspect of the disclosure may include continuously receiving a core drilled from a formation into an open end of a chamber while removing the core distal from the open end of the chamber. The method further includes obtaining a measurement relating to property of interest of the core using at least one sensor; and estimating the property of interest of the core using the obtained measurement.

    摘要： An apparatus and method is disclosed for measuring a parameter of an earth formation surrounding a wellbore. A Nuclear Magnetic Resonance (NMR) tool and at least one second tool are conveyed in the wellbore on a wireline, the NMR tool having a magnetic influence on a region of the wellbore. The magnetic influence of the NMR tool is removed from the region of the wellbore using a demagnetizing device. The parameter of the earth formation is measured using the at least one second tool. A second demagnetizing device may be used to remove the magnetic influence of the at least one second tool from the region of the wellbore.

    摘要： The downhole tool disclosed herein comprises a body, a flexible member attached to the body, and a transducer housed in the body. The flexible member compresses against one side of the wellbore and urges the body against the other side. The transducer emits a signal to the flexible member reflectable from the flexible member back to the transducer. The signal travel time from the transducer to the flexible member and back is analyzed for estimating the distance between the body and the flexible member. The standoff distance can be estimated from the distance between the body and the flexible member. From the standoff distance, the wellbore diameter is estimated. The tool may also obtain wellbore dimensions by obtaining near side wellbore standoff and using a magnetic ruler to determine bowspring flexing. The magnetic ruler results may be used in conjunction with or without the far side standoff data.
