A tubular injector with snubbing jack and oscillator, which eliminates the need for overhead tubular and oscillator support structure and utilizes resonant vibration to remove tubulars (2) and other objects which are stuck in a well. In a first embodiment the apparatus includes a mechanical oscillator (22) mounted on a snubbing jack (30), wherein the tubular load on the snubbing jack (30) can be released and transferred to the oscillator (22) when the tubular (2) is stuck, for vibrating and loosening the tubular (2) in the well. In another embodiment the apparatus is designed to handle coiled tubing (6) and a snubbing-type jack (39) is used in association with a conventional coiled tubing guide (37) and a coiled tubing injector (14), for guiding the coiled tubing (6) from a reel through the guide (37) and through a hollow tubular stem (9) in the oscillating apparatus (22), into the injector (14) and the well.
A tubular injector apparatus for inserting a jointed tubular into a well bore of an oil or gas well and lifting the tubular from the well bore, said tubular injector apparatus comprising a snubbing jack for selectively inserting the tubular into the well bore and lifting the tubular from the well bore and an oscillator provided on said snubbing jack for selectively engaging the tubular and vibrating the tubular in the well bore.
A tubular injector apparatus for inserting a jointed tubular into a well bore of an oil or gas well and lifting the tubular from the well bore, said tubular injector comprising a snubbing jack for selectively inserting the tubular into the well bore and lifting the tubular from the well bore;
A coiled tubing injector apparatus for inserting coiled tubing into a well bore of an oil or gas well and lifting the coiled tubing from the well bore, said coiled tubing injector apparatus comprising a coiled tubing injector for selectively inserting the coiled tubing into the well bore and lifting the coiled tubing from the well bore;
A coiled tubing injector apparatus for inserting a coiled tubing into a well bore of an oil or gas well, lifting the coiled tubing from the well bore and freeing coiled tubing in the well bore, said coiled tubing injector apparatus comprising a coiled tubing injector for selectively inserting the coiled tubing into the well bore and lifting the coiled tubing from the well bore;
A method of using an oscillator with a snubbing jack in oil or gas well applications for receiving tubulars in a well, said method comprising:
