Abstract
Example methods, apparatus and articles of manufacture to measure gas reservoir formation pressures are disclosed. A disclosed example method includes positioning a downhole bubble sensor in a wellbore formed in a geological gas reservoir formation, trapping a fluid in a portion of the wellbore including the bubble sensor, pressurizing the trapped fluid, reducing pressurization of the fluid until the bubble sensor detects one or more bubbles in the fluid, recording a pressure of the fluid when the bubble sensor detects the one or more bubbles, and determining a formation pressure of the gas reservoir from the recorded pressure.
