The present disclosure relates to gravity feeding coiled tubing (CT) into a live well. A method may include gravity feeding the CT into the live well having a wellhead, a line in fluid communication with the wellhead, a CT stripper and pressure control equipment (PCE) disposed above the wellhead, and a safety valve disposed below the wellhead, the method comprising: injecting a fluid through the line and into the wellbore to displace reservoir fluid positioned above the safety valve such that at least a portion of the reservoir fluid is forced below the safety valve; closing the safety valve; releasing pressure from between the PCE and the safety valve via the line; gravity feeding the CT into the wellbore; isolating pressure between the PCE and the safety valve; manipulating pressures on both sides of the safety valve; opening the safety valve; and gravity feeding the CT past the safety valve.
