摘要： A method for fracturing a subterranean formation is provided in which inert masking material particles are injected into the formation with a dissolution agent so that the masking material inhibits dissolution where it contacts a portion of one or both fracture faces. The undissolved regions provide support to keep the fracture open after the treatment and the dissolved regions provide a conductive pathway for flow of fluid to or from the wellbore.

摘要： A dry solid composition is disclosed that, when added to an aqueous liquid, provides a slurry that can be used in sandstone acid fracturing. The slurry generates hydrofluoric acid downhole to etch the sandstone fracture faces created. The chemical and physical properties of the composition result in very uneven etching of the fracture faces, enhancing the fluid conductivity of the final fracture. Optionally, inert masking materials may be included in the dry composition, or added to the slurry, to increase the inhomogeneity of the etching and further increase the fluid conductivity.

摘要： A method for stimulating thick or multilayered heterogeneous or homogeneous formations in a single trip without packers involves perforating with tubing conveyed perforation, then injecting a self-diverting acid, then moving the tubing string and perforating at a new location, and then injecting additional self-diverting acid. The sequence may be repeated. The acid is preferably a viscoelastic diverting acid. The self-diverting acid may be alternated with conventional treatment fluid. The job is designed to treat the least permeable zone(s) first and maximizes acid efficiency.

摘要： A method is given for acid fracturing a subterranean formation for improving the flow of fluids. The principal source, optionally the sole source, of the acid is a solid acid-precursor, optionally injected with an additional solid that is inert and that masks a portion of the newly created fracture faces so that the fracture face etching by the acid is not uniform. The method ensures a good flow path for fluids between the fracture tip and the wellbore.

摘要： Propped fractures in formations from which fluids are produced are described that have wormholes extending out into the formations from the faces of the fractures at locations distant from boreholes. Methods are given for creating such propped fractures having wormholes in which either a closed propped fracture is formed and then the wormholes are formed, or the entire fracture and channel system is formed before the closure occurs.

摘要： An interface device and method for interfacing instruments to a medical procedure simulation system serve to interface peripherals in the form of mock medical instruments to the medical procedure simulation system computer to enable simulation of medical procedures. The interface device includes a housing having a mock bodily region of interest to facilitate insertion of a mock instrument, such as an endoscope tube, into the interface device. The mock bodily region of interest may be pivotable to simulate various patient orientations. The instrument is engaged by a capture mechanism in order to measure rotational and translational motion of the instrument. An actuator is disposed within the interface device to provide force feedback to the instrument. The measured motion is provided to the computer system to reflect instrument motion on the display during the simulation. Alternatively, the interface device may be configured to accommodate instrument assemblies having a plurality of nested instruments (e.g., sheath, catheter and wire), whereby the interface device individually grasps, measures manipulation of and provides force feedback to the nested instruments. In addition, the interface device may be configured to simultaneously accommodate a plurality of independently inserted instruments.

摘要： A method is given for treating a subterranean formation penetrated by a wellbore with a viscosified fluid. The fluid contains a solid hydrolysable polyacid that upon dissolution and hydrolysis releases an acid that is a breaker for the viscosifying system. Suitable solid hydrolysable polyacids include polylactic acid and polyglycolic acid. The fluid also contains a pH control agent, present in an amount sufficient to neutralize any acid present in the solid hydrolysable polyacid before the injection and to neutralize any acid generated by the solid hydrolysable polyacid during the injection, so that the acid breaker is not available to break the fluid during the injection. In one embodiment the viscosifier is a viscoelastic surfactant fluid system and the solid hydrolysable polyacid is of a size selected to be a fluid loss additive, for example in fracturing or gravel packing. In another embodiment, the solid hydrolysable polyacid is used in particles sufficiently small that they enter the pores of the formation. In either case, the viscosifier is broken after the solid releases more acid than can be neutralized by the pH control agent.
摘要翻译：给出了用增稠液体处理井眼渗透的地层的方法。流体包含固体可水解的多酸，其在溶解和水解时释放酸，该酸是用于增粘体系的断裂剂。合适的固体可水解的多元酸包括聚乳酸和聚乙醇酸。流体还含有pH控制剂，其量足以中和注射前固体可水解的多元酸中存在的任何酸，并且在注射期间中和由固体可水解的多元酸产生的任何酸，使得酸性破坏剂不可用在注射期间打破流体。在一个实施方案中，增粘剂是粘弹性表面活性剂流体系统，并且固体可水解的多元酸的尺寸被选择为流体损失添加剂，例如在压裂或砾石包装中。在另一个实施方案中，固体可水解的多元酸以足够小的颗粒使用，使得它们进入地层的孔。在任一种情况下，在固体释放比可以被pH控制剂中和的酸更多之后，粘稠剂被破坏。
