Abstract: A retrievable compression set packer is sequentially released. First the sealing element is allowed to relax. Then the upper slip has wedging action that forces it against a surrounding tubular relaxed. After that the upper slips are pulled up to retract them fully allowing the packer to come out. These sequential actions are done with a mandrel movement in one direction. The sealing element is released with undermining a collet by aligning collet heads with a recess on the mandrel. The slip force release happens with mandrel movement forcing a ring into a wedge such that circumferential force on slip segments is reduced or eliminated when the wedge is pushed out of its conforming slot allowing for circumferential flexibility of the slip seat. The mandrel then picks up a slip ring that retracts the slip segments on the slip seat and the packer is removed.

Abstract: The devised modular of ‘Subsea Level Gas Separator of Oil Well Effluent (SLGOE) precludes giant gas entrainment entering the rig. The effluent, past the BOP, is diverted by gravity through a ‘diversion’ tube, into the bottom of 1-3 ‘gas separator’ tanks, creating fountain-like flow. The downstream, syphoned from an ‘oil passage tank’, joins the partitioned collection system past the ‘diversion’ tube. The large top outlets of ‘all’ tanks let off ‘instantly’ rising gases. In another embodiment of two ‘gas separator’ tanks, oil flows from the top of the first. Its bottom outlet directs it into the top of the second. From it, oil is siphoned to the collection system. The large top outlets of both tanks instantly let off gases. In either device, the gas ‘instantly’ separates from the effluent tossed into aerial milieu of the tanks, a simplest model conceivable, the laws of nature taken advantage of.

The method comprises positioning an acoustic device in a well located within the geological formation and performing an acoustic treatment impacting a muddled zone in cycles comprising one or more manipulated waves of ultrasonic pressure on the muddied zone.
