Abstract:
A mobile chemical mixing and injection unit adapted for use during the extraction of an oil/water/sand slurry from an oil field storage tank wherein said tank has a body of accumulated sand therein. The unit comprises a motorized truck body having a flat bed with a water storage tank and two mixing tanks mounted thereto. A high pressure injection pump pumps water from the water storage tank to the oil field storage tank and creates a slurry. The slurry is pumped to an adjacent settlement tank hopper where the oil, water and sand will stratify. An effective amount of a flocculating agent, coagulating and surfactant are mixed in each of the water filled mixing tanks and then pumped into the slurry to facilitate separation of oil, sand and water. The high pressure injection water and the water for the mixing tanks are replenished by pumping water from the settlement tank hopper thereby ensuring a continuous process until the field storage tank is cleaned.

Abstract:
One embodiment of the invention disclosed is an apparatus for separating a solid material from a mixture containing oil, water, clay, sand, soil and drill cuttings. The apparatus comprise a series of processing cells and wash tanks. Hydrocyclonic devices are also used to further purify the solid mixture for disposal.
Abstract:
An apparatus for removing formation sand from an oil storage tank. The apparatus is mounted to a truck towable trailer so that it may be transported to remote sites. Mounted to the truck towable trailer is a container adapted to accept and dewater a sand-water slurry pumped from the oil storage tank. The slurry is formed by injecting high pressure water from a water reservoir mounted to the truck towable trailer into the approximate centre of mass of the formation sand by way of a pipe having a nozzle generating a spherical spray pattern within the slurry. The pipe is forced into the slurry by way of a two counter-rotating drive wheels in frictional contact with the pipe. Included in the apparatus is a bifurcated conduit adapted for attachment to the storage tank drain port adapted for the injection of high pressure through one branch of the conduit and withdrawal of slurry from the other branch and into the container by way of a slurry pump. The dewatering of the slurry takes place by a plurality of screen filters mounted to the bottom, side and front inside walls of the container. Oil and water extracted from the slurry is recycled back into the storage tank for later removal and treatment. All pumps and conduits are mounted to the truck towable trailer so that the apparatus is self-contained.
