Patent number: 10301930Abstract: A method for determining the presence of a leak in a pressure system. The method includes receiving pressure data of the pressure system after shut-in of the pressure system, determining a pressure slope based on the pressure data, entering a passing state in response to the slope being less than a predetermined slope threshold, exiting the passing state in response to the slope being greater than the predetermined slope threshold, and generating a passing indication as a result of remaining in the passing state for at least a predetermined time period.Type: GrantFiled: October 17, 2013Date of Patent: May 28, 2019Assignee: INNOVATIVE PRESSURE TESTING, LLCInventors: Charles M. Franklin, Richard A. Cully

Patent number: 10161243Abstract: A method for determining the presence of a leak in a pressure system. The method including receiving pressure data of the pressure system after shut-in of the pressure system, determining a pressure slope and a pressure curvature based on the pressure data, and generating a failing indication as a result of the pressure slope being above a predetermined threshold and the pressure curvature indicating that the slope is constant or increasing in absolute value.Type: GrantFiled: October 17, 2013Date of Patent: December 25, 2018Assignee: INNOVATIVE PRESSURE TESTING, LLCInventors: Charles M. Franklin, Richard A. Cully

Patent number: 9983091Abstract: A method for identifying a leak in a pressure system. The method includes receiving, from a pressure sensor, pressure data of a fluid contained in the pressure system, determining a slope and curvature of the pressure data, determining a ratio of the curvature to the slope of the pressure data, and monitoring the ratio over a period of time. The method also includes, as a result of a non-constant component of the ratio exceeding a predetermined threshold, generating an indication that a leak may be present in the pressure system, or as a result of the ratio including no non-constant component or a non-constant component below the predetermined threshold, generating an indication that no leak is present in the pressure system.Type: GrantFiled: March 4, 2016Date of Patent: May 29, 2018Assignee: INNOVATIVE PRESSURE TESTING, LLCInventors: Charles Mark Franklin, Richard A. Cully

Publication number: 20160363500Abstract: A system includes a memory and a processor coupled to the memory. The processor receives a description of a pressure system, including a plurality of components to be tested, where each component has a required test pressure. The processor generates a first test sequence that tests the required test pressure of each of the plurality of components, where the first test sequence includes a first number of steps. The processor also iteratively generates a second test sequence that tests the required test pressure of each of the plurality of components, where the second test sequence comprises a second number of steps. The processor stores a representation of at least one of the first test sequence and the second test sequence in the memory, and the second number of steps is less than the first number of steps.Type: ApplicationFiled: January 23, 2015Publication date: December 15, 2016Applicant: Innovative Pressure Testing, LLCInventors: Charles M. FRANKLIN, Richard A. CULLY

Patent number: 9518461Abstract: A method for determining integrity of a wellbore. The method includes underbalancing a volume of fluid in the wellbore, receiving pressure data of the wellbore after shut-in of the wellbore, determining a pressure curvature based on the pressure data, and generating a failing indication as a result of the pressure curvature indicating that the slope is constant or increasing in absolute value. The failing indication indicates fluid communication across a wellbore boundary.Type: GrantFiled: January 23, 2015Date of Patent: December 13, 2016Assignee: INNOVATIVE PRESSURE TESTING, LLCInventors: Charles M. Franklin, Richard A. Cully

Patent number: 9207143Abstract: A leak detection system includes a pressure system that requires leak and/or pressure testing. A pressure sensor coupled to the pressure system senses a first pressure at time t0, after which fluid pumping system provides a selected volume of test fluid to the pressure system. The pressure sensor senses a test pressure at time t1 and at selected intervals ānā to time t(n+1) and transmits a signal reflective of the pressures at each time to a computer system for recording and storage on a computer readable medium. A software application operating on the computer system is configured to calculate a leak detection value, which is a function of a ratio of the first pressure at time t0 and the test pressure at time t1; the test pressure at time t1 and the test pressure at time t2; and so on to a test pressure at the timen and the test pressure at the time t(n+1). A graphical output displays the leak detection value as a function of time.Type: GrantFiled: November 8, 2011Date of Patent: December 8, 2015Assignee: Innovative Pressure Testing, LLCInventors: Charles M.
