An apparatus includes a dissolvable gauge cutter, a temperature sensor, and a pressure sensor. The dissolvable gauge cutter is made of a dissolvable alloy. The dissolvable gauge cutter is configured to be disposed within and travel through a tubular installed within a wellbore. The dissolvable gauge cutter is configured to dislodge solids from an inner wall of the tubular as the dissolvable gauge cutter travels through the tubular down to a specified depth within the wellbore. The dissolvable gauge cutter is configured to completely dissolve after reaching the specified depth. The temperature is configured to measure a temperature of a surrounding fluid as the dissolvable gauge cutter travels downhole through the tubular to the specified depth. The pressure sensor is configured to measure a pressure of the surrounding fluid as the dissolvable gauge cutter travels downhole through the tubular to the specified depth.

Computer-implemented systems and computer-implemented methods include the following. A choke/pressure control valve (PCV) gas rate is determined for each well of a group of producing wells. A downstream temperature (DST) gas rate is determined for each well of the group of producing wells. Parameters for a well rate test are determined for each well of the group of producing wells using the choke/PCV gas rate and the DST gas rate. A total gas rate for the producing wells is determined using the parameters. A gas production allocation factor (G-PAF) for the producing wells is determined. A production allocation for each well of the producing wells is determined using the total gas rate.
