A method and apparatus for treating a subterranean section surrounding a wellbore with a fluid. In one embodiment, the apparatus comprises a three-dimensional tubular element capable of fluid flow in a wellbore with at least one burst disk with a pre-determined pressure rating positioned at a desired location on the tubular wherein the burst disk ruptures at the pre-determined pressure at the desired location on the tubular in the wellbore. The method provides the ability to choose the order in which the subterranean interval sections surrounding a wellbore are treated with fluid.

Hydraulically controlled burst disk subs and methods for their use

A method is disclosed for treating drilling mud discharged from a well wherein the mud contains drill cuttings and paramagnetic materials such as hematite. The drilling mud is first passed through a high-gradient magnetic separator to separate the paramagnetic materials from the drilling mud. The drilling mud is then passed through a centrifuge separator to remove the drill cuttings from the drilling mud.

Method for separation of solids from drilling fluids by magnetic

A process for separating liquid hydrocarbons from a wastewater using acoustic energy below cavitation is disclosed. The wastewater containing the residual hydrocarbons is introduced into a vessel which has at least two groups of acoustic transducers attached to it. Acoustic energy is applied to the fluid at an intensity below cavitation level and sufficient to induce at least one standing wave in the fluid. The liquid hydrocarbons are allowed to coalesce within the vessel to a coalesced droplet size of about 20 microns. These coalesced hydrocarbons are then separated from the wastewater.

Acoustic separation of liquid hydrocarbons from wastewater

A process for separating solids from a fluid using at least one polymer and acoustic energy at or above cavitation is disclosed. The fluid containing the polymer is flowed into a vessel and acoustic energy is applied to the fluid at intensity sufficient to induce cavitation within the fluid. At least a portion of the solids are allowed to agglomerate in at least one position within the vessel. The agglomerated solids are then separated from the fluid.

Solid-liquid separation process using at least one polymer and

A process for dewatering an aqueous fluid containing solids using water-absorbent substances is disclosed. A water-absorbent substance and a body to which the solids will adhere are added to the solids-containing aqueous fluid. The water-absorbent substance absorbs water and the solids coat the solids-adhering body. The water-laden substance may then be separated from the solid-adhering body that is coated with solids, thereby separating the water and the solids.
