1. A visual inspection system for inspection of lateral wellhead inlet ports and an outermost casing annulus adjacent to a port in oil, gas, and/or geothermal wells, comprising:
a camera insertion system that includes a camera and a light source assembly to inspect a lateral access port of a wellhead,
wherein the camera and light source assembly are configured to be propelled to inspect the lateral access port and a valve attached thereto and to an annular space adjacent to an annular access port, such that the visual inspection is performed in conjunction with an annulus intervention procedure,
wherein the visual insertion system is run in conjunction with an annulus hose insertion apparatus to allow the visual inspection system to be stroked in under pressure, through relevant gate valves to view an annulus area, such that the visual inspection system inspects the annulus access port prior to running the annulus intervention system,
wherein the annulus hose insertion apparatus has a shaft that is configured to extend such that the camera and light source assembly is installed onto the distal end of the shaft,
wherein the shaft is configured to project forwardly to traverse the camera and light source assembly through the lateral access port and any valve attached thereto and into the annulus, and
wherein the shaft is configured to be rotated as it is extended creating a helix that provides full coverage of inner surfaces of the valve, an entryway, and the annulus area and spot rotations at points of interest to investigate specific areas as the shaft is extended.
