    摘要： A package and methods for treating a wellbore using the same. In one embodiment, the method comprises servicing a wellbore in contact with a subterranean formation by placing a material in the wellbore, wherein the material is disposed within a closed container. The material is suitable for use in a wellbore and is capable of plugging a flow pathway. The method further comprises releasing the material from the container. In an embodiment, the material is a swelling agent, which may plug a permeable zone.

    摘要： Methods of cementing in a subterranean formation include passing a swelling agent to a permeable zone in a subterranean formation. The swelling agent is combined with a carrier fluid before being passed to the permeable zone. Upon contacting an aqueous fluid, the swelling agent swells in the permeable zone. The aqueous fluid may already be present in the subterranean formation, or alternatively, it may be introduced to the subterranean formation after passing the swelling agent into the subterranean formation. The swelling agent substantially inhibits a cement slurry subsequently pumped into the subterranean formation from passing through the permeable zone. The cement slurry therefore continues flowing down through the casing and up through the annulus where it sets and forms a strong cement column.

    摘要翻译： 在地层中固井的方法包括使溶胀剂通过地层中的可渗透区域。 溶胀剂在被传送到渗透区之前与载体流体结合。 在与含水流体接触时，溶胀剂在可渗透区域中膨胀。 含水流体可能已经存在于地层中，或者可以在将溶胀剂通入地层之后引入地下地层。 溶胀剂基本上抑制随后泵送到地层中的水泥浆通过可渗透区。 因此，水泥浆料继续向下流过套管并向上流过其所在的环形区并形成一个坚固的水泥柱。

    摘要： An additive for addition to conventional well treatment fluids to enhance the ability of the fluids to be recovered from subterranean formations, to generate a foam in association with the fluids and/or to enhance the ability of the fluids to remove water and other connate fluids interlocked with gas in the formations. The additive includes about 25% to about 50% by volume of a microemulsion generating component which forms an acid and/or water external microemulsion when added to the treatment fluid, and about 50% to about 75% by volume of a foaming agent component. The foaming agent component includes at least one nonionic surface active agent having an HLB of from 12 to 22. The additive is particularly suitable for addition to foam fracturing fluids useful for stimulating tight or otherwise unconventional gas formations. Also provided are a gas well treatment composition employing the inventive additive and a method of treating a subterranean formation in which the inventive composition is employed.

    摘要： An improved method for fracturing oil wells is disclosed and claimed herein. In particular, the present invention involves the determination of the direction of fracture propagation, i.e., perpendicular to the minimum stress existing within a given formation and the alignment of perforations produced by a variety of perforating devices with the previously determined direction of fracture propagation. The methods disclosed and claimed herein will eliminate many problems encountered in the prior art, including reducing the pressure required to initiate fractures and reducing the undesirable effects of near well bore tortuosity.

    摘要： Methods of completing poorly consolidated subterranean formations bounded by one or more consolidated formations to prevent sand production from the poorly consolidated formations are provided. The methods basically comprise the steps of drilling a well bore into the consolidated boundary formation adjacent to the poorly consolidated formation, creating a propped fracture communicating with the well bore in the consolidated boundary formation which extends into the poorly consolidated formation and producing fluids from the poorly consolidated formation into the well bore by way of the propped fracture.

    摘要： A fracture oriented completion tool system for use in a casing string in a wellbore. The completion tool comprises a casing valve having a radioactive source therein, the orientation of which may be determined by use of a detector apparatus, such as a rotational gamma ray detector. The casing valve thus may be aligned with the fracture of a zone of interest in the well. A plurality of casing valves may be used, with at least one having a radioactive source. A swivel connection may be used to interconnect the casing valve so that housing ports therein may be aligned as the casing is run into the wellbore. In one preferred embodiment, the swivel connection is a locking swivel connection. A method of positioning a casing string in the well utilizing the completion tool is also disclosed.
