A gas lift injection packer assembly, a gas lift injection system that includes the assembly, and methods utilizing the assembly and system. The gas lift injection packer assembly includes a top sub, a packer coupled to the top sub, a bottom sub coupled to the packer, a sleeve disposed within the top sub, the packer, and the bottom sub. The inner diameters of the components of the gas lift injection packer assembly form a continuous passage from end-to-end of the gas lift injection packer assembly such that a downhole tool can be moved through the gas lift injection packer assembly while the gas lift injection packer assembly is sealed in a wellbore. A gas inlet port of the top sub can be formed such that an inner wall of the gas inlet port is the housing for a check valve.
Methods and compositions utilize a sand obtained by combining a dirty sand with a chemical additive, where the combination decreases the water drain time through the sand compared to the sand without the chemical additive. The decrease of water drain time reduces the amount of time to dry the sand after a wash, and when using the sand for proppant, promotes conductivity of fluid through the sand when the sand is in a fracture of a subterranean formation.
Methods of treating a produced water having one or more water soluble organic compounds (WSO) dispersed therein include mixing the produced water with 1 ppm to 50,000 ppm by weight of an adsorbent particulate to form a slurry; and separating a purified produced water from the slurry, wherein the purified produced fluid includes a lower concentration of one or more WSO than the produced fluid, wherein WSO is the fraction of the dissolved and dispersed hexane extractable compounds in the produced water that does not flash off at 85ºC, and adsorbs onto silica gel.
