Abstract
A system for evaluating the leak tightness of a connector, or multiple connectors. The system uses an administrative server having a library of pressure and temperature information on various connectors, as well as the ability to report pressure and temperature data to a network as uncorrected and corrected responses. The system uses a data logger for recording pressure and temperature readings and also reporting corrected and uncorrected responses using one or more equations to shorten the test time by at least 50 percent or to about 5 minutes or less. The system uses a test pump for applying pressure to a connector to generate a corrected pressure which indicates leaks when the corrected pressure changes.
Claims21
A system for evaluating leak tightness of at least one connector for control conduits usable with field completions, well drilling, or combinations thereof, comprising:
- a. an administrative server comprising an administrative processor and administrative data storage, wherein the administrative data storage comprises a library of pressure and temperature information on connectors and equations, in an administrative dynamic information database, computer instructions for producing a report of recorded pressures and temperatures and corrected pressures and pressure decay rates, and computer instructions to transmit the report of recorded pressures and corrected pressures and computed pressure decay rates using at least one network;
- b. a data logger in communication with the administrative server, wherein the data logger comprises a data logger housing for supporting a display, wherein the display is connected to a data logger processor with data logger data storage, at least one USB port, a power supply, and a parallel port;
- and wherein the data logger data storage stores at least one equation that produces a pressure decay rate for at least one connector secured to a control conduit at a defined pressure over time for at a defined temperature, and wherein the data logger data storage further comprises computer instructions for:
- (i) instructing the data logger processor to record pressure readings from at least one connector;
- (ii) instructing the data logger processor to record temperature readings from the at least one connector;
- (iii) instructing the data logger processor to generate a report of an uncorrected responses using the recorded pressure readings and recorded temperatures readings;
- and
- (iv) instructing the data logger processor to generate a report of a corrected response using the recorded pressure and temperature readings and at least one equation;
- c. a test pump in communication with the data logger, wherein the test pump is adapted to produce pressures of at least 10,000 psi and flow pressurized test fluid from a fluid source, which comprises a reservoir of test fluid to the connector;
- and, a test pressure exceeding a desired corrected response pressure is applied with the test pump to the connector, the test pump is isolated, pressure and temperature readings are recorded into the data logger data storage, pressure and temperature readings are presented on the display, the recorded pressure and temperature readings are processed by the data logger processor using at least one equation to produce a corrected pressure, the corrected pressure is displayed, and when the corrected pressure changes, an alarm is provided indicating a leak between the connector and the control conduit and wherein the test is completed within 5 minutes.
