A hydraulic setting tool. The tool is configured to allow hydraulic setting of a bridge plug, packer or other radially expansive mechanical well isolation mechanism. Wireline or slickline deployment may be utilized. In either case, parameters of the setting application may be recorded. In the case of wireline deployment such parameters and downhole data may be monitored in real-time allowing an operator to make intelligent setting application adjustments as necessary.

1. A method of setting a downhole radially expandable well isolation mechanism in a well, the method comprising: deploying a hydraulic setting tool into a well using a line, wherein the hydraulic setting tool comprises:a housing sleeve having an annulus;a chamber wall connected with an interior surface of the housing sleeve, wherein the chamber wall traverses the annulus; andan extension located within the annulus, wherein the extension has an extension wall connected therewith and wherein the extension wall traverses the annulus and engages an inner surface of the housing sleeve in a sealing relationship, and wherein the extension wall and chamber wall define a sleeve chamber therebetween, and wherein the extension is in communication with a pump, wherein the extension has one or more ports to provide fluid in the sleeve chamber, and wherein the extension is directly coupled with a mechanism;providing fluid to the sleeve chamber, moving the housing sleeve relative to the extension, thereby setting the mechanism; andmeasuring the pressure in the sleeve chamber using a sensor and recording setting data during the setting of the mechanism. 2. The method of claim 1, wherein the setting data comprises pressure, pump speed, or combinations thereof. 3. The method of claim 1, wherein the setting data comprises stain gauge measurements acquired during setting. 4. The method of claim 1, wherein the setting further comprises: anchoring the mechanism at the location; andsealingly isolating the well at the location. 5. The method of claim 1, further comprising: disconnecting the extension from the mechanism; andremoving the hydraulic setting tool from the well. 6. The method of claim 5, further comprising running a perforating application, stimulating application, or combinations thereof. 7. The method of claim 1, wherein the line is a wireline cable. 8. The method of claim 7, further comprising monitoring setting data in real-time over the wireline cable. 9. The method of claim 8, further comprising adjusting the setting based on the monitoring of the setting data. 10. The method of claim 1, further comprising testing the setting tool in advance of deploying. 11. The method of claim 10, wherein the testing comprises ensuring the tool is capable of effectively achieving the setting. 12. The method of claim 10, wherein the testing comprises determining a predetermined system pressure capacity of the tool. 13. A data acquiring hydraulic setting tool comprising: an extension directly connected with a mechanism at one end and in communication with a pump at another end;an extension wall connected with the extension;a port located below the extension wall;a housing sleeve disposed about the extension, wherein the housing sleeve is configured to move relative to the extension and compress the mechanism, and wherein the extension wall engages an inner surface of the housing sleeve;a chamber wall connected with an inner surface of the housing sleeve, wherein the chamber wall and extension wall form a sleeve chamber therebetween; anda sensor configured to measure the pressure in the sleeve chamber. 14. An assembly for providing isolation in a well, the assembly comprising: an extension configured in communication with a pump at one end;an extension wall connected with the extension;a port located below the extension wall;a housing sleeve disposed about the extension, wherein the housing sleeve is configured to move relative to the extension, and wherein the extension wall engages an inner surface of the housing sleeve;a chamber wall connected with an inner surface of the housing sleeve, wherein the chamber wall and extension wall form a sleeve chamber therebetween;a sensor configured to measure the pressure in the sleeve chamber; anda mechanism directly connected with another end of the extension and operatively aligned with the housing sleeve, and wherein the mechanism is configured to be released from the extension after actuation of the mechanism.
