    Abstract: A measurement device is configured in a shaped charge package to be utilized in a perforating gun section tool string. The measurement device may include for example thermal conductivity detectors (TCD) configured to measure fluid flow velocity and/or thermal characteristics of the flowing fluid. The measurement device may include for example a pair laterally spaced TCDs each having sensor faces positioned co-planar with a surface across which the fluid flows. The measurement device may include a recessed TCD, having a sensor face recessed below an opening in the exterior surface.

    Abstract: Example methods and apparatus for determining downhole parameters are disclosed herein. An example method includes pumping a fluid in a first direction to substantially fill a first area of a fluid flow passageway with the fluid and determining a fluid parameter via a sensor disposed in a second area adjacent the first area. The sensor includes a heater and a temperature sensor. The example method also includes determining if the first fluid has flowed in a second direction into the second area based on the fluid parameter.

    Abstract: Apparatus and methods for determining downhole fluid parameters are disclosed herein. An example method includes disposing a sensor in a fluid in a wellbore. The sensor includes a heater and a temperature sensor, and the fluid is flowing at a velocity of about zero centimeters per second to about ten centimeters per second. The fluid includes particulates, paraffin or asphaltenes. The example method further includes obtaining a first measurement via the heater and obtaining a second measurement via the temperature sensor. Based on the first measurement and the second measurement, the velocity of the fluid is determined.

    Abstract: Example methods and apparatus for analyzing operations are disclosed herein. An example method includes disposing a sensor in a fluid flow passageway. The sensor has a heater and a temperature sensor. The example method further includes obtaining a first response of the sensor to a fluid flowing in the fluid flow passageway and transmitting a signal to a tool to operate the tool. Operation of the tool is to affect a fluid parameter of the fluid. The example method also includes obtaining a second response of the sensor to the fluid flowing in the fluid flow passageway and determining if the tool has operated based on the first response and the second response.
