Abstract:
1. A method for designing a closed-chamber formation test system, comprising: a. collecting data identifying physical and fluid properties of an earth formation and a well drilled through the formation; b. estimating initial parameters of the closed-chamber formation test system for testing the earth formation, comprising an initial pressure in a test chamber of the test system and the test chamber volume, c. simulating a closed-chamber formation test over a period of time by: d. comparing the simulated time to complete the test to a preselected testing time range; e. adjusting initial estimated parameters of the closed-chamber formation test system and repeating c1, c2, and c3 using the data and adjusted parameters, if the simulated time to complete the test is not within the preselected testing time range; f. outputting to a storage medium a final set of parameters for designing the closed-chamber formation test system when the simulated time to complete the test is within the preselected testing time range.
