Abstract:
A modular ‘Sea Level Gas Separator of Oil Well Effluent’ (SLGOE) unit is devised to prevent damage to the riser/conductor, as well as precluding the gas entrainment reaching the rig, upon a well blow-out. The effluent, after a blow-out, is let into ‘gas-separator’ tank of the unit, entering as a down-flow, whereby instantaneous separation of the gases is effectuated. Massively clustered top outlets let off the rising gases to a distant destination. An immensely pressured gas entrainment is attenuated by enormous receptive volume of the multiple upstream outlets of the tanks, the containing volume and pressure of a gas being inversely proportional. The gas entrainment is further precluded to entrain into the down-streaming oil of the tanks, reaching a different destination. When the drilling conductor is breached, an ‘oil separator’ tank separates the oil from admixed water, whereby the pollution of oceanic water is also precluded.

Claim (Index 5):
The preferred prototype embodiment of the SLGOE unit of claim of  1 , wherein the prototype modular SLGOE unit is set forth as: (1) an Emergency operational SLGOE unit (an EOS unit) within the rig vicinity, connected to the well's annulus \u2018A\u2019 and functions to separate the diverted oil-gas effluent, when the production tubing is damaged with or without damage to the well's marine riser; (2) a multi-operational SLGOE unit (a MOS unit), within the rig vicinity, wherein it functions to separate oil-gas effluent on a regular basis and also after a well blow-out, receiving the blown-out effluent from the damaged production tubing, with or without a damage to the well's marine riser, the details of said operations arc as set forth below\u2014\n (1) the EOS unit\u2014\n (a) the drilling conductor and the marine riser are closed from the rig by an air tight closure of any size and configuration, with provisions to undo, said closure located about the rig level, \n (b) a sturdy \u2018production tubing shield\u2019 envelopes the production tubing up to the rig level serving to protect the deployed structures of the riser upon a blow out; (ii) a wide effluent \u2018diversion tube\u2019 starts in the bottom of the annulus \u2018A\u2019 and rises to a level above the surface water, where it emerges from the riser and the conductor to enter the gas separator tank of the EOS unit about the rig site, (iii) the course of the \u2018diversion tube\u2019 with multiple converging tubules is set forth to adapt to the structural complexity of the riser interior, whereby the deployed structures within the riser are protected from being otherwise blown off by a pressured gas entrainment; (iv) the diversion tube is normally closed by one way outlet valves about its emerging site from the riser, said outlet valves opening upon moderate pressure; (v) the common gas collection tube leaving the EOS unit's modular has similar one way outlet valves opening upon moderate pressure; (vi) the atmospheric air is normally not contained, in the modular the tanks, the gas receptacles, and the tubular system of the EOS unit, after they are evacuated initially to be replaced by oxygen free air, \n (c) following tubing, effluent enters the \u2018production tubing shield\u2019 (PTS) to then be flowing into the diversion tubing to reach the EOS unit; (ii) Following damage to the PTS\u2014with the rig level closure sealing the riser and the conductor from the rig, the pressured effluent is forced into the \u2018diversion tubing\u2019 to reach the EOS unit, wherein by gaseous separation within the tanks, the gas entrainment is attenuated, with the oil and gas reaching their separate destinations; (iii) following damage to production tubing the effluent finds its way also to the rig level through a partially damaged production tubing, however bypasses the rig flow through the MOS unit, for eliminating its gaseous components to be then returned, (iv) wherein a production tubing is not yet installed, the blown out effluent, whether of single or of admixed element(s), entering only the \u2018diversion tubing\u2019, \n (d) following damage to the riser with the well's drilling conductor intact, and the rig level closure sealing the riser and the conductor: (i) the effluent flows into the diversion tubing to reach the EOS unit, wherein by gaseous separation within the tanks, the gas entrainment is attenuated, with the components of oil and gas reaching separate destinations; (ii) the effluent finds its way into a Partially damaged production tubing, however bypasses the rig to flow through the MOS unit, for eliminating its gaseous components to be then returned to the rig, the events not different from those wherein only the production tubing is damaged, \n (e) following damage to the drilling conductor, the damaged production tubing, the riser and the conductor communicate with the ocean water, and the effluent's flow through both the production tubing and the diversion tubing stop, the pressure and fluid level within the riser and the conductor equalizing with ocean waters, though some flow through the production tubing may continue, the set forth mechanical forces being partially operable, \n (f) wherein there is damage to the drilling conductor and the effluent is flowing into the ocean waters: (i) a strong rubber sheath with its top hardware is articulated with and cemented to the complimentary hardware located all around the drilling conductor at different strategic levels, the chosen higher level of the conductor hardware deemed to surpass all the breaches to the conductor; (ii) a bottom level hardware about the bottom edges of the rubber sheath, surpassing the diameter of disruption (DOD) about the ocean grounds, is cemented to the ocean floor, while the liquid column within the conductor/riser is suctioned out from the rig level; (iii) following, the well is sealed with a pneumatic sealer, followed by a permanent structuring of a \u2018NEW INNERMOST REPARATIVE CASING\u2019 to seal all the leaks including those to the distant ocean craters, \n \n (2) the MOS unit\u2014\n the MOS unit located in the rig vicinity, though otherwise similar as a prototype model, is multi-operational as set forth below\u2014 \n (a) the MOS unit receives the effluent directly from the production tubing/oil collection system, however, initially by-passing the rig, \n (b) it receives the well effluent at all times, to separate its gaseous elements, and additionally, it receives the effluent after a blow-out, as part of the blown-out effluent, apart from flowing into the annulus A, also flows through the production tubing to the rig level, \n (c) separated gas either entrained or not, reaches a distant destination. \n (d) separated oil returns to the rig, transiting through an oil tank wherein oil at high pressure threshold is let out through massive pipe with one way valves, \n (e) the atmospheric air is initially not contained in the modular, the tanks, the tubular system, and the gas receptacles of the MOS unit, after they are evacuated and replaced by oxygen free air,
