Methods and apparatus for obtaining an indication of fluid in-flow in a section of a gas well having multiple perforations through which fluids comprising gas and/or liquid enter the well are described. In an example, the temperature within the section of the gas well is monitored at a plurality of locations. The locations comprising (a) a first set of locations, at or near a perforation; and (b) a second set of locations at which the temperature is substantially independent of the effects of the inflow of gas at a perforation. An indication of temperature excursions at the locations is obtained and used to obtaining an indication of the inflow of fluids to the well by relating the indications of temperature excursions from the second set of locations to liquid inflow and relating the indications of temperature excursions from the first set of locations to liquid and gas inflow. |
