Abstract: Methods include introducing a multistage treatment fluid into one or more intervals of a wellbore, wherein the treatment fluid contains one or more stages of a polymer-forming composition and one or more stages of a spacer fluid and initiating polymerization of the one or more stages of polymer-forming composition. Methods may include designing a multistage treatment fluid containing one or more stages of a polymer-forming composition and one or more stages of a spacer fluid, wherein or more stages of the polymer-forming composition comprises a thermosetting polymer; and pumping the multistage treatment fluid into a wellbore, wherein the pumping rate is determined by constructing a model based upon (a) the minimum pumping rate determined from the critical reaction temperature and the downhole temperature, (b) the fracture closing time, (c) the temperature within one or more fractures, and (d) the maximum pumping rate.

Abstract: Procedures include designing parameters for cementation jobs based upon the wellbore geometries and loading conditions. The cementation parameters such as Young's modulus are selected such that longitudinal crack propagation is inhibited. Procedures also include determining critical loading conditions for an already-cemented casing annulus based upon the specified cement properties and wellbore conditions. The critical loading conditions are determined such that longitudinal crack propagation in the cement is inhibited. Techniques are used to improve the friction coefficients between the casing and cement to inhibit longitudinal crack propagation. The treatments can include forming surface patterns that enhance friction and/or making the casing surface oleophopic and/or hydrophilic.

Abstract: Methods and apparatus of adjusting matrix acidizing procedures are disclosed. An example method includes determining parameters of a wellbore fluid during a matrix acidizing procedure using at least a first sensor and a second sensor. The parameters include velocity of the wellbore fluid and a temperature difference between the first sensor and the second sensor. The method also includes, based on the parameters, determining a characteristic relative to an invasion length of a reactive fluid within the formation, the reactive fluid used in association with the matrix acidizing procedure.

Abstract: Methods of treating a subterranean formation penetrated by a wellbore may include injecting a multistage fracturing treatment into the wellbore comprising one or more stages of geopolymer precursor composition containing a geopolymer precursor and an activator, and one or more stages of a spacer fluid; and curing the one or more stages of geopolymer precursor composition. In another aspect, methods of treating a subterranean formation penetrated by a wellbore may include injecting a multistage fracturing treatment into the wellbore that include one or more stages of geopolymer precursor composition, wherein the geopolymer precursor composition includes an emulsion having an oleaginous external phase, and an internal phase comprising one or more surfactants, a geopolymer precursor, and an activator, and one or more stages of a spacer fluid; and curing the one or more stages of geopolymer precursor composition.

Abstract: A method of performing a cementing operation with an expandable cement deployable into a wellbore penetrating a subterranean formation is provided. The method involves determining design parameters of a wellsite, determining at least one estimated eigenstrain of the expandable cement based on the design parameters, selecting the expandable cement based on the estimated eigenstrain, and validating the selected expandable cement by comparing the estimated eigenstrain with the empirical eigenstrain. The design parameters includes a minimum pre-stress of the wellbore sufficient to prevent creation of a microannulus in the wellbore. The estimated eigenstrain is sufficient to generate the determined minimum pre-stress.

Abstract: Embodiments may generally take the form of a degradable composite structure and a method for controlling the rate of degradation of a degradable composite structure. An example embodiment may take the form of a degradable polymer matrix composite (PMC) including a matrix having: a degradable polymer, a fiber reinforcement, and particulate fillers. The fiber loading is between approximately 10% to 70% by weight and the particulate loading is between approximately 5% to 60%.
