ABSTRACT:
A method for running tools in an oil or gas well includes the running of an elongated small diameter tubing string from a coil stored on a reel down into the oil and gas well. A fluid conveying carrying tool is secured to the lowermost distal end portion of the coil tubing string so that fluid can circulate from the coil tubing wound upon the reel into a tool assembly. Fluid (or pressurized gas) can be introduced into the well through the tubing so that it circulates through the tubing and then into the tool carrier. A tool such as a wire-line tool is supported by the tool carrier so that pinching can be applied to the tool with the coil tubing string with the tool carrier forming a load transfer interface between the coil tubing string and the wire-line tool.
