1. An apparatus comprising:
a pressure sensor for measuring a pressure in a wellbore of a formation;
a processor communicably coupled with the pressure sensor; and
a non-transitory machine-readable medium having program code executable by the processor to cause the apparatus to,
obtain a set of measurements with the pressure sensor;
determine an effective wellbore compressibility coefficient based on the set of measurements;
determine at least one of: a fluid parameter or a wellbore parameter, or modify a well operation, based on the effective wellbore compressibility coefficient;
generate a dataset comprising a set of wellbore compressibility values and a set of formation measurements, each of the set of wellbore compressibility values corresponding with at least one of the set of formation measurements; and
train a machine learning algorithm using the dataset.
