Abstract: A method and apparatus for use in hydrocarbon exploration. The method and apparatus improve downhole flow back control in oil and/or gas wells by controlling fluid entry into the well bore. Either a single limited entry opening or a small cluster of limited entry openings is provided in a well liner or casing and cement sheath allowing fluid communication between a region of a well bore and a subterranean reservoir. The method also uses the limited entry opening or the cluster during an injection treatment of the subterranean reservoir to control fluid entry. The method also provides a proppant flow back treatment following the injection treatment of the subterranean reservoir.

Abstract: A bottomhole assembly (BHA) and method for stimulating a well includes setting a packer of the BHA in a wellbore. The BHA includes the packer and a jetting tool coupled to a tubing string. Process fluid is pumped down the tubing string and jetted with the jetting tool to perforate a formation. Stimulation process fluid is pumped down an annulus of the wellbore to fracture the formation.

Abstract: The invention relates to methods and apparatus for creating multiple fractures in subterranean formations. The apparatus is a jetting tool having a plurality of sets of jetting nozzles so that the sets of nozzles are substantially parallel to one another such that parallel cavities may be formed substantially simultaneously in the formation. The jetting nozzles may be adapted to provide a fluid jet that flares outwardly from the nozzle. The nozzles also may be aligned such that cavities in the formation overlap to form a single cavity. The nozzles may be further adapted so that holes jetted into the casing thereby are still spaced from one another. Methods of fracturing subterranean formations using the apparatus are also disclosed.

Abstract: The invention provides a method of treating a subterranean formation penetrated by a wellbore, the method comprising the steps of: (a) mixing a particulate and an active material to obtain an at least partially coated particulate, wherein: (i) water forms a contact angle of less than 90 degrees with a surface of the particulate, (ii) the active material is capable of forming a coating on the particulate, (iii) the active material forms a contact angle less than 90 degrees with the particulate, and (iv) water forms a contact angle of greater than 90 degrees with a layer of the active material; (b) mixing the at least partially coated particulate and a carrier fluid to obtain a treatment fluid; and (c) introducing the treatment fluid into the subterranean formation through the wellbore to deposit the at least partially coated particulate into the subterranean formation.

Abstract: Methods of initiating a fracture tip screenout, that comprise pumping an annulus fluid into an annulus, between the subterranean formation and a work string disposed within a wellbore penetrating the subterranean formation, at an annulus flow rate; and reducing the annulus flow rate below a fracture initiation flow point so that the fracture tip screenout is initiated in the one or more fractures in the subterranean formation, are provided. Also provided are methods of fracturing a portion of a subterranean formation and methods of estimating a fracture initiation flow point.

Abstract: A system and method for fracturing a hydrocarbon producing formation in which a fracturing tool is inserted in a wellbore adjacent the formation, and fracturing fluid is introduced into the annulus between the fracturing tool and the wellbore and flows to the formation.

Abstract: According to one embodiment of the invention, a flow conditioning system for fluid jetting tools includes a housing having a plurality of jet nozzle openings and a fluid straightener disposed within the housing. The fluid straightener is defined by one or more vanes, and the vanes form a plurality of flow channels within the housing. Each flow channel is associated with at least one jet nozzle opening.

Abstract: A wellbore completion design is provided, which creates a convective flow action that separates water and sand from hydrocarbons during production of the hydrocarbons from a subterranean formation. A deviated section of the wellbore creates the desired effect. The wellbore completion design may include a secondary bore, which intersects the deviated section of the wellbore at an acute angle, to accumulate the separated water and sand. An injection pump disposed in the toe section of the secondary bore can also be employed to pump the water back into the water containing portion of the subterranean formation. If solids are present in more than trace amounts, the toe section of the secondary bore may be formed at an acute angle to the remaining portion of the secondary bore to prevent blockage of the pump. Alternatively, a tertiary bore may be provided, so that the solids can accumulate in the secondary bore and the water can flow into the tertiary bore.

Abstract: The present invention is directed to a method and apparatus for fracturing a subterranean formation which use a liner fracturing tool. The liner fracturing tool consists of a liner, with at least one jet extending through the liner. During fracturing operations, fracturing fluid is pressured through the jet to form microfractures. Fractures are formed by the stagnation pressure of the fracturing fluid. The jets may be mounted within a jet holder that may be dissolved following fracturing operations to allow reservoir hydrocarbons to flow into the liner more readily.

Abstract: The present invention relates to subterranean well stimulation. More particularly, the present invention relates to improved methods of stimulating subterranean formations during drilling operations. In some embodiments, the present invention discloses methods of stimulating a section of a subterranean formation comprising (a) forming at least a portion of a well bore that at least penetrates a section of the subterranean formation using a drilling operation; (b) stimulation a section of the subterranean; and (c) continuing the drilling operation. In other embodiments, the present invention discloses methods of stimulation a section of a subterranean formation comprising (a) forming at least a portion of a well bore that at least penetrates a section of the subterranean formation using a drilling operation; (b) stimulating a section of the subterranean formation; and (c) continuing the drilling operation.

Abstract: The present invention is directed to a method of isolating hydrajet stimulated zones from subsequent well operations. The method includes the step of drilling a wellbore into the subterranean formation of interest. Next, the wellbore may or may not be cased depending upon a number of factors including the nature and structure of the subterranean formation. Next, the casing, if one is installed, and wellbore are perforated using a high pressure fluid being ejected from a hydrajetting tool. A first zone of the subterranean formation is then fractured and stimulated. Next, the first zone is temporarily plugged or partially sealed by installing an isolation fluid into the wellbore adjacent to the one or more fractures and/or in the openings thereof, so that subsequent zones can be fractured and additional well operations can be performed.

Abstract: A fluid inflatable packer includes a mandrel having an elongated tubular body with a number of openings along its length or other open architecture. An inflatable element is disposed about the elongated tubular body of the mandrel or the interior of the fluid inflatable packer. The inflatable element is exposed to an interior of the mandrel through the openings or otherwise. The inflatable element expands and contracts with pressure of process fluids in the interior of the mandrel or the fluid inflatable packer. The process fluids may be unfiltered and include five or more pounds of sand or other solids per gallon.

Abstract: A bail-type animal trap for small rodents and the like, having a self-setting triggering mechanism. The trap includes a spring-loaded, bail-type striker which is hinged to the upper surface of the base. The striker is releasably retained in the cocked position by a resilient latch which is connected by a wire or rod to a trigger plate which is adapted to hold a piece of bait. The trigger plate engages a stop affixed to the base. The trigger plate includes an integral catch for engaging the stop, and an integral fulcrum which causes the trigger to release when it is either lifted, depressed, or moved sideways. The striker further includes a self-setter which returns the trigger plate to the set position each time the trap is sprung.
