    摘要： A sample while logging tool for downhole fluid sampling and production logging may include a sample collector sub and a sensor sub. The sample collector sub may include a body defining a bore extending from a first end to a second end. One or more sample chambers may be housed in the bore. The sample chamber may collect a fluid sample. At least one probe may be coupled to the sample chamber to measure fluid properties of the collected fluid sample within the sample chamber and transmit the fluid properties. A piston may be coupled to the first end having a gate distal to the first end. The piston may be actuated to open and close an opening of the sample chamber. Additionally, the sensor sub may measure and transmit data on fluids within a well to form production logging data.

    摘要： A method comprises receiving a measurement of a pressure in a subsurface formation at a number of depths in a wellbore formed in the subsurface formation across a sampling depth range of the subsurface formation to generate a number of pressure-depth measurement pairs and partitioning the sampling depth range into a number of fluid depth ranges. The method comprises performing a fitting operation over each of the number of fluid depth ranges to determine a fluid gradient for the type of the reservoir fluid for each of the number of fluid depth ranges. The method comprises generating a solution set of one or more solutions based on the fluid gradient of the reservoir fluid for each of the number of fluid depth ranges determined from performing the fitting operation, wherein each solution defines a partitioning of the sampling depth range and the fluid gradient of each fluid depth range.

    摘要： A method of determining a fluid parameter includes receiving, by a processor and from a plurality of sensors coupled to a flexible tube, fluid information. The flexible tube includes a throat arranged in a first position with respect to a fixed end. The fluid information includes a strain or pressure at a first portion of the flexible tube and a strain or pressure at a second portion of the flexible tube. The method also includes determining a first fluid parameter of the fluid and transmitting, from the processor to a controller operationally coupled to the throat, second position information including a second position of the throat different than the first position. The method also includes receiving, with the throat in the second position, second fluid information and determining, based on the second fluid information, a second fluid parameter of the fluid.
