摘要： Tubewaves are used for detection and monitoring of feature state to enhance stimulation operations and remediate failure conditions. For example, proper sealing of perforations may be confirmed based on lack of a reflection of a tubewave by the perforations. Alternatively, at least one of amplitude, frequency, attenuation, dispersion and travel time associated with a tubewave and reflection may be used to determine feature state. If a sealant fails during treatment then the failure condition is indicated by appearance of a tubewave reflection. Consequently, the stimulation operation can be stopped in a timely manner, and remediation by means, for example, of pumping diversion fluid or dropping of balls, can be reinitiated until the difference between the expected responses and responses measured by the instrument along the segment to be stimulated confirm that sealing has taken place and that stimulation of the intended zone can resume. Further, specific remediation steps may be selected based on response of the borehole system to tubewaves. The efficacy of the selected remediation steps may also be determined by response of the borehole system to tubewaves during or after execution of those steps.

摘要： A field-responsive fluid which enters a semi-solid state in the presence of an energy field is improved by use of a plurality of energy field responsive particles which form chains in response to the energy field. The particles can be (a) composite particles in which at least one field-responsive member having a first density is attached to at least one member having a second density that is lower than the first density, (b) shaped particles in which at least one field-responsive member has one or more inclusions, and (c) combinations thereof. The particles improve the field-responsive fluid by reducing density without eliminating field-responsive properties which afford utility. Further, a multi-phase base fluid including a mixture of two or more substances, at least two of which are immiscible, may be used. The multi-phase base fluid improves the field-responsive fluid because surface tension between the boundaries of the immiscible substances in conjunction with chains formed by field-responsive particles tends to stop or retard creep flow, resulting an improved dynamic or static seal.
摘要翻译： 通过使用响应于能量场形成链的多个能量场响应颗粒来改善在存在能量场的情况下进入半固体状态的场响应流体。 颗粒可以是（a）复合颗粒，其中具有第一密度的至少一个场响应构件附着到具有低于第一密度的第二密度的至少一个构件，（b）成形颗粒，其中至少 一个场响应构件具有一个或多个夹杂物，和（c）它们的组合。 颗粒通过降低密度来改善场响应流体，而不消除提供效用的场响应特性。 此外，可以使用包括两种或更多种物质的混合物的多相基流体，其中至少两种物质是不混溶的。 多相基础流体改善了场响应流体，因为不可混溶物质的边界与由场响应颗粒形成的链结合的表面张力倾向于停止或延缓蠕变流动，导致改进的动态或静态密封。

摘要： A self-adaptive cement system includes cement, water and at least one additive that reacts or/and expands in contact with oil and gas. Several chemical products have been identified including rubber alkylstyrene, polynorbornene, resins such precrosslinked substituted vinyl acrylate copolymers and diatomaceous earth. These additives have the effect of making the cement self-healing in the event of physical failure or damage such as micro-annuli. The self healing property is produced by the contact with subterranean hydrocarbon fluids, the potential repair mechanism is thus activated if and when needed in case of start of loss of zonal isolation. In another embodiment, the expansion is deliberately induced by pumping a hydrocarbon fluid in the vicinity of the set cement.
