A de-sanding tank with a vertical exterior wall and an interior conical bottom with a solids outlet located at a lower tip of the conical bottom. Downwardly and tangentially oriented water jet nozzles within the tank cause a swirling action to remove solids. An enclosing space located between the vertical wall and the conical bottom has a honey-combed structure of closed pore foam as reinforcement for the conical bottom. Compartments within the honey-combed structure fill with water as the vessel is placed in service to add support for the conical bottom. Water enters the compartments via downwardly facing bottom openings that fill a common void located at the bottom of the enclosing space and then into the compartments. Weep holes provided between the top of each compartment and the interior of the tank allow the air from the compartments to enter the tank as the compartments fill.

A method and apparatus for separating the constituents of a drilling fluid into two or more groups based on particulate size and specific gravity in a continuous flow process.

Provided is a backflow collection system that includes a collection vessel having an upper section and a lower section, the collection vessel having a side opening configured to receive backflow from an oil/gas well, as well as a discharge port proximate an upper end of the upper section configured to discharge pressurized gas from the collection vessel. The backflow collection system may further include an auger coupled proximate the lower section of the collection vessel, the auger configured to receive solid and liquid matter from a bottom opening in the lower section, and when elevated remove at least a portion of the solid and liquid matter from the collection vessel, the collection vessel designed such that when fluid is contained therein it acts as a liquid/gas seal to prevent the pressurized gas from exiting through the bottom opening in the lower section of the collection vessel.

A method and system for treatment of flow-back and produced water from a hydrocarbon well in which fracturing operations are carried out using a phase separation and creating of positive charge in the water.

Treating and conditioning liquid sludge and a solidified sludge cake obtained thereby are disclosed. A first emulsion of sludge is formed in an in-line container fed at a first flow rate Q owing to the impact of the sludge with air injected into the container at a rate Q, where Q>5Q, in a first region which has a small volume of less than 0.05 m3. The first emulsion is then transferred into a second region of the container extending over a first length, and is then discharged via a component which generates a head loss in a chamber extending over a second length. A flocculant is injected in order to obtain a second coagulated emulsion, which is at least partially degasified. The matter in suspension in the second emulsion obtained in this way is then filtered or decanted.
