摘要： A method is described to predict the composition of favorable bridging agents for a particular situation in which the solution thermodynamics of the chemicals used in the composition of the bridging material is carefully evaluated. Wellbore service fluids are also described that contain materials such as sodium bicarbonate, a material such as a salt containing water in a crystal structure, a material containing at least one boron-oxygen bond, or a non-polymer material having low solubility at low temperatures and high solubility at temperatures close to an expected long-term static bottom hole temperature. The material is provided in aqueous medium in sufficient concentration in the aqueous medium so as to act as a diverting agent during a hydraulic fracturing procedure using the fluid. The wellbore service fluid is pumped through the wellbore and the flow of the fluid is diverted using a plug that subsequently substantially dissolves due to changes in temperature and/or pressure.

摘要： The present Invention relates generally to the field of petroleum production. More specifically, the present Invention relates to a method for stimulation of reservoirs for fluid production. A method of treating a subterranean formation includes the initial stage, wherein a fracture is propped with a conventional proppant mixed with an encapsulated tackifying (adhesive) compound. The amount of encapsulated tackifying compound preferably varies from about 0.01 to about 20 weight per cent relative to the proppant. An encapsulated adhesive compound and proppant may be pre-mixed or a mixture may be prepared on the fly at the well site and than introduced into the subterranean formation. A second stage includes fracture closure that leads to capsule breakage and release of the adhesive compound.

摘要： A method is given for treating a wellbore in a subterranean formation by hydraulic fracturing, slickwater fracturing, gravel packing, and the like, by using plate-like materials as some or all of the proppant or gravel. The plate-like materials are particularly useful in complex fracture systems, for example in shales. They may be used as from about 20 to about 100% of the proppant. Relative to conventional proppants, plate-like proppants demonstrate (a) enhanced crush resistance of the proppant due to better stress distribution among proppant particles, (b) diminished proppant embedment into formation fracture faces due to the greater contact surface area of proppant particles with the formation, (c) better proppant transport due to lower proppant settling rates, (d) deeper penetration into branched and fine fracture networks, and (e) enhanced proppant flowback control. Preferred plate-like proppants are layered rocks and minerals; most preferred is mica.

摘要： Hydraulic fracture dimensions and, optionally, fracture closure pressure and time are determined by adding particulate matter that discharges to create an acoustic signal to the proppant, allowing the particulate matter to discharge, and detecting the acoustic signal with geophones or accelerometers. The particulate matter may be spheres or fibers. The discharge may be explosion, implosion, detonation, or rapid combustion or ignition. The discharge may be triggered by fracture closure or by chemical reaction.

摘要： A method for preparing a formation surrounding a wellbore to bear hydrocarbons through a borehole is disclosed. In one step, a bottomhole assembly is inserted into the borehole. The formation is drilled with the bottomhole assembly. The formation may be characterized with logging tools, probes, sensors, seismic system and/or the like to create first information. One or more fractures are placed in the formation without removal of the bottomhole assembly from the wellbore. Further, continuous drilling of the formation is performed with the bottomhole assembly after/during placing the fractures. Further characterizing of the formation with the probes, sensors/systems or the like is performed to produce second information. Another fracture is placed with feedback from the second information. Repeating the drilling, characterizing and placing of fractures as necessary during the formation preparing process.

摘要： A method of determining wettability of a rock sample, such as from a core sample is described. The sample is preferably crushed or comminuted to a particulate size where micro fractures have been eliminated, but where the particles are still large enough to represent the native rock matrix and texture. The comminuted core sample is exposed to a test fluid for a given period of time. The rock sample can be split into many separate aliquots, and a series of tests is performed using a series of different fluids and/or the same fluid for different exposure times. The excess test fluid residing on the surfaces of sample particles is removed. The test fluid imbibed into the interior of the particulate sample is then measured. The test fluid can be, for example, water, a non-aqueous fluid, and/or a solution of miscible solvents. The technique used to measure the imbibed fluid depends on the solvent (imbibing fluid) being studied. In one example, this technique includes both gravimetric determination and quantitative chemical analysis. The detection of water can be via Karl Fischer titration.

摘要： Solid material required at a subterranean location is supplied from the surface suspended in a carrier liquid and agglomerated below ground by means of a binding liquid. Agglomeration is achieved by arranging that the binding liquid and the particulate solid are similar to each other but opposite to the carrier liquid in hydrophilic/hydrophobic character. The solid and the binding liquid may both be hydrophobic while the carrier liquid is hydrophilic, or vice versa. The solid may be hydrophobically surface modified to render it hydrophobic. The binding liquid may be provided as a precursor which converts to the binding liquid below ground to trigger agglomeration after arrival at the subterranean location. The agglomerates may function as proppant heterogeneously placed in a fracture of a reservoir, or may serve to block an unwanted path of flow. The binding liquid may polymerise after agglomeration so as to stabilise and strengthen the agglomerates.
