Patent Images
1. A process for wellbore characterization, the process comprising:
- separating, in a separation vessel, drilling mud from gas produced during drilling of a wellbore;
transporting the separated produced gas from the separation vessel to a downstream process;
measuring at least one of a temperature and a pressure of only the separated produced gas during transport using one or wore sensors;
measuring at least one of a mass flow rate and a volumetric flow rate of only the separated produced as during transport using one or more ultrasonic sensors;
determining at least one of a standard volumetric flow rate and an average molecular weight of the separated produced gas based on the measuring; and
determining properties of the well bore based on the determined standard volumetric flow rate or the determined average molecular weight.

Abstract
An apparatus and a process for wellbore characterization are disclosed, including: separating, in a separation vessel, drilling mud from gas produced during drilling of a wellbore; transporting the separated produced gas from the separation vessel to a downstream process; and measuring at least one of a temperature, a pressure, a mass flow rate, and a volumetric flow rate of the separated produced gas during transport using one or more sensors. Properties of the gas separated from the mud may be used to determine characteristics of a wellbore.
