Methods for initiating chemical reactions in a wellbore include delivering one or more reactive components via a carrier fluid to the wellbore. The one or more reactive components delivered to the wellbore are configured to enable one or more chemical reactions to occur. The one or more chemical reactions are carried out until a threshold volume of the one or more reactive components is delivered to the wellbore.

Systems and methods of initiating energetic reactions for reservoir stimulation

A technique for providing a fluid conduit between a main bore and a substantially non-producing region of a fracture at a horizontal section of the bore. The technique includes forming a micro-tunnel from a location of the bore adjacent the fracture. The micro-tunnel may be directed at the non-producing region with a angled deflector or in a steerable manner. Additionally, the well may be configured with micro-tunneling at the outset or retrofitted with micro-tunnels as a manner of restoring production.

Attaining access to compromised fractured production regions at an oilfield

A slurry for treating a wellbore, comprising a base fluid and a plurality of pre-processed fiber flocks dispersed in the base fluid.

Pre-processed fiber flocks and methods of use thereof

A method for completing a wellbore traversing a subterranean formation includes making electromagnetic resistivity measurements along a lateral section of the wellbore. The resistivity measurements are evaluated to estimate a water content of the subterranean formation along the lateral section. The formation is fractured at selected regions along the lateral section at which the water content is below a threshold and avoiding regions at which the water content is above the threshold.

Engineering completion and selective fracturing of lateral wellbores

A downhole tool system may include one or more containers to hold waste product and a tractor to convey the one or more containers to a storage location within a wellbore. The downhole tool system may also include an anchor to seal against the wellbore and secure the containers at the storage location. Additionally, the downhole tool system may include a disconnect tool to separate the tractor from the containers such that the tractor may be removed from the wellbore while leaving the containers at the storage location.

Systems and methods for downhole deployment of containers

Apparatuses and methods for positioning a flexible hose into a wellbore with a protective housing are disclosed. A flexible hose is contained within a protective housing and both are positioned into a wellbore to a desired depth. Pressure can be applied to an interior of the protective housing, and a packoff seals between the flexible hose and the protective housing, causing the pressure to eject the hose from the protective housing.

Controlled release of hose

A technique facilitates hydrocarbon fluid production. A well is formed in a subterranean region by drilling a borehole, e.g. a generally vertical wellbore. At least one tunnel is formed and oriented to extend outwardly from the borehole at least 10 feet into a formation surrounding the borehole. The orientation of the at least one tunnel is selected such that it extends at a desired angle with respect to a direction of horizontal stress in the formation. A fracture stimulation of the at least one tunnel is performed to create a network of fractures. The orientation of the at least one tunnel ensures that the network of fractures extends through a target zone in a hydrocarbon bearing region of the formation.

Reservoir stimulation comprising hydraulic fracturing through extended tunnels

Methods of delivering reactive components to a geological formation disclosed herein include generating a plurality of microholes along a wellbore, the plurality of microholes comprising one or more openings, and the plurality of microholes are configured to connect the wellbore to the geological formation. Methods further include delivering the one or more reactive components to the plurality of microholes via a carrier fluid, wherein the one or more reactive components are configured to enable one or more chemical reactions to occur, and wherein the carrier fluid is configured to expand, and controlling a flow rate of the one or more reactive components based on whether a volume of the one or more reactive components delivered to the plurality of microholes is greater than a threshold volume.

Methods of treating a subterranean formation are disclosed that include introducing a treatment fluid including shaped particle and/or shaped uniform particles into a subterranean formation via a wellbore, and creating a plug including the shaped particle and/or shaped uniform particles of the treatment fluid.

Methods of zonal isolation and treatment diversion with shaped particles

A method for drilling and fracturing a subterranean formation includes drilling a substantially horizontal pilot well from a previously drilled vertical pilot well. A plurality of substantially vertical sidetracks is drilled from the horizontal pilot well. Fracturing fluid is pumped into the plurality of vertical sidetracks to hydraulically fracture the subterranean formation.

Vertical drilling and fracturing methodology

Methods of treating a subterranean formation penetrated by a well bore, by providing a treatment fluid comprising a blend including a first amount of particulates having a first average particle size between about 3 mm and 2 cm and a second amount of particulates having a second average size between about 1.6 and 20 times smaller than the first average particle size or a second amount of flakes having a second average size up to 10 times smaller than the first average particle size; by introducing the treatment fluid into the well bore; and by creating a plug with the treatment fluid.

Methods of zonal isolation and treatment diversion

Gas fracturing methods and systems utilizing a gas treatment fluid, which may contain a dispersed phase of fluid loss control agent particles. Also, treatment fluids suitable for use in the methods and systems are disclosed.

Gas fracturing method and system

A method may include preparing a map of cement quality for one or more intervals of a wellbore; determining anticipated regions of fluid communication and anticipated regions of zonal isolation from the map of cement quality; and designing a stimulating treatment based on the presence of regions of fluid communication.

Methods of evaluating cement isolations and quality

A method for treating a subterranean formation penetrated by a wellbore, comprising: providing a treatment slurry comprising a carrying fluid, a solid particulate and an agglomerant; injecting the treatment slurry into a fracture to form a substantially uniformly distributed mixture of the solid particulate and the agglomerant; and transforming the substantially uniform mixture into areas that are rich in solid particulate and areas that are substantially free of solid particulate, wherein the solid particulate and the agglomerant have substantially dissimilar velocities in the fracture and wherein said transforming results from said substantially dissimilar velocities is provided.
