Abstract:
An apparatus for hydrocarbon production testing, and intended to be mounted in a well having an expected permeable first formation to be production tested, and an expected second penneable formation, said apparatus comprising: one or more sensors, meters, regulators, or controllers for carrying out a corresponding hydrocarbon production sensing, measuring, recording pressure condition or flowing rate determination step relative to hydrocarbon fluid traveling within the well, said apparatus further comprising one or more channel-forming pipes having fluid ports which, within the well, establish a hydrocarbon fluid flow path between the first formation to be production tested and the second permeable formation, and said one or more channel forming pipes being designed to be isolated, testing in use, relative to fluid flow to or from a surface from which the well extends, and at least one seal element provided within the well in order to restrict the fluid flow between the first and second formations to said fluid flow path so as to avoid fluid communication between the two permeable formations other than through said fluid flow path.
