Herein is described a fluid that is useful in consolidating a formation without the use of a gravel pack and screen. In particular, the fluid is useful in consolidating heterogeneous formations where the permeability is not uniform over-the total formation thickness, e. g. a formation having at least a first layer and a second layer, wherein the permeability of the first layer is greater than that of the second layer. The fluid comprises at least one of a resin, a curing agent, and a surfactant, wherein the fluid is self-diverting. Optionally, a catalyst or other additives, such as an oil wetting agent, can be used. Fluids of the present invention are self-diverting, i. e. in a formation comprising at least a first layer and a second layer, wherein the first layer has a higher permeability than the second layer, the depth of penetration of the fluid into the second layer will be greater than that predicted from the permeability ratio (the ratio of the permeability of the first layer to that of the second layer). Self-diversion can be achieved by structuring the fluid by incorporation of another phase, either liquid or gas, or by using an additive in the fluid. Also disclosed are methods for using such a fluid to consolidate a formation, especially a heterogeneous formation.

A method is given of fracturing a subterranean formation including the step of a) pumping at least one device actively transmitting data that provide information on the device position, and further comprising the step of assessing the fracture geometry based on the positions of said at least one device, or b) pumping metallic elements, preferably as proppant agents, and further locating the position of said metallic elements with a tool selected from the group consisting of magnetometers, resistivity tools, electromagnetic devices and ultra-long arrays of electrodes, and further comprising the step of assessing the fracture geometry based on the positions of said metallic elements. The method allows monitoring of the fracture geometry and proppant placement.

A method and apparatus for producing gas from a hydrate formation includes the use of at least one wellbore which penetrates the hydrate formation and further extends into an aquifer below the hydrate formation. The aquifer provides relatively warm water which may be produced up and into the hydrate formation thereby causing the release of gas from the hydrate. Suitable flow control and monitoring equipment may be included to control the flow of water produced from the aquifer and gas produced from the hydrate formation.

A method and apparatus for improving reservoir communication includes, in one arrangement, causing creation of tunnels in surrounding formation of a well interval, and applying treatment fluid to the tunnels. A local transient underbalance condition is created in the well interval after creation of the tunnels in the formation and application of the treatment fluids.

A hydraulic fracturing method is disclosed that includes designing a fracture treatment including a fluid pumping schedule to fracture a subterranean formation according to a design model that accounts for cumulative filter cake thickness, including polymer concentrated at the fracture surfaces, to provide a propped fracture width effectively greater than the cumulative filter cake thickness, and injecting fluids through a wellbore into the formation essentially according to the fluid pumping schedule of the fracture treatment design. A fracturing method is also disclosed that includes placing a high breaker loading in the filter cake. A composition is disclosed which comprises a fluid viscosified with a polymer and a fluid loss additive comprising a delayed breaker.

Methods and tools are described to reduce sanding including the steps of fracturing the cement sheath in a localized zone around the casing and having the fractured zone act as sand filter between the formation and openings in the casing, with the openings being best pre-formed but temporarily blocked so as to allow a conventional primary cementing of the casing. The fracturing step can also be used for remedial operation to reopen blocked formation or screens.

A method of treating a subterranean formation penetrated by a wellbore includes preparing a treatment fluid with shear thinning, non-monotonic rheological properties, injecting the treatment fluid into the subterranean formation, and inducing shear rate softening phase transition in the treatment fluid. The non-monotonic rheology properties can be such that in the relationship between shear stress (σ) versus strain rate ({dot over (γ)}), where {dot over (γ)}

A method for optimizing fracture treatments includes interpreting a nominal pump schedule corresponding to a nominal value for each fracture control parameter. The method further includes interpreting environmental variables, and interpreting probability distributions for each of the environmental variables that is uncertain. The method further includes defining an objective function such as a net present value of each fracture treatment over a 365 day period following the fracture treatment. The method includes determining an optimal value for each fracture control parameter according to the objective function by determining the fracture control parameter values that yield the best mean net present value given the variability in the environmental variables as described by their probability distributions.
