Formation fluid analysis apparatus and related methods are disclosed herein. An example apparatus includes a sample platform coupled to production tubing disposed in a wellbore and a first chamber defined by the sample platform. The first chamber is to capture a fluid flowing through the production tubing. The example apparatus includes a second chamber coupled to the sample platform. The example apparatus includes a first sensor coupled to the sample platform and a controller. The sample platform, the second chamber, and the first sensor are to be communicatively coupled to the controller. The controller is to selectively instruct the second chamber to one of depressurize or pressurize the fluid, the first sensor to generate fluid data for the fluid during the depressurization or the pressurization of the fluid and conduct a pressure-volume analysis for the fluid based on the fluid data.
