摘要： A composition and method are given for self-destructive fluid loss additives and filter cakes in wellbores and subterranean formations. The fluid loss additives and filter cakes are formed from a mixture of particulate solid acid-precursors, such as a polylactic acid or a polyglycolic acid, and particulate solid acid-reactive materials, such as magnesium oxide or calcium carbonate. In the presence of water, the solid acid-precursors hydrolyze and dissolve, generating acids that then dissolve the solid acid-reactive materials. The composition is used in oilfield treatments such as drilling, completion and stimulation where it disappears when it is no longer needed without the use of mechanical means or injection of additional fluids.

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： 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. To achieve agglomeration, 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.

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： This invention relates to methods for stimulating oil production from well by pumping reactive stimulation fluids from the well into the formation. The methods are particularly relevant to cold heavy oil production. This invention provides methods of stimulating production from a formation surrounding a well, comprising pumping a fluid from the well into the formation so as to create a hydraulic fracture, wherein the fluid contains one or more reactive species that destabilise cohesive forces in the formation matrix, and allowing the fluid to leak of into the formation and react with the formation matrix so as to produce a destabilised zone in the formation around the location of the fracture such that formation fluids and sand particles can be produced from the formation through the zone and into the well. The methods preferably comprise selecting the fluid so as to produce an at least partially unconsolidated formation matrix in the destabilised zone. It is particularly preferred to produce fluids from the formation so as to cause worm-holing in the destabilised zone. The fluid can contain additives in liquid form, solid or granular form. It is also preferred that the fluid acts as a diluent for heavy oil and can also modify formation fluid rheology.

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.
