摘要： A method for estimating a property of an earth formation, the method includes: conveying a carrier through a borehole penetrating the earth formation; irradiating the formation with neutrons from a neutron source disposed at the carrier; detecting a first signal from the formation due to the irradiating using a first radiation detector, the first signal being related to a saturation of a fluid in the formation; detecting a second signal from an element in the formation due to the irradiating using a second radiation detector, the second signal being related to an element emitting the second signal in the formation; and estimating the property from the first signal and the second signal.

摘要： A perforating system having a perforating gun with a gun body formed from a ductile material. The gun body deforms under pressure while maintaining sufficient structural integrity to remain intact, and without rupturing or leaking. A flowable material can be inserted within the gun body that provides additional support to the gun body.

摘要： A lock for a perforating gun system comprising, a housing, a cylinder formed in the housing, a piston assembly disposed within the cylinder, and anchoring arms coupled with the piston assembly. Detonation of the shaped charges of an associated perforating gun produces a pressure surge which is communicated to a surface of the piston assembly. Appropriate movement of the piston assembly outwardly rotates the anchoring arms into anchoring engagement with an associated tubular. Thus the pressure from the detonation event will anchor a perforating system within its associated tubular.

摘要： A perforating system having a perforating gun with a high pressure gun body. The gun body can be thickened so that no empty space is present between it and a corresponding gun tube. Alternatively, the gun body could be a solid cylinder with slots radially formed therein to receive a shaped charge. In another embodiment, a flowable material, such as foam, fluid, sand, ceramic beads, eutectic metal, and combinations thereof, is provided in the space between the gun body and gun tube.

摘要： A method and system for cementing and perforating a wellbore in a single step by coupling a perforating gun with a wiper plug. The method includes injecting cement in a wellbore having casing therein and an annulus between the casing and wellbore. A wiper plug is dropped on the cement having a perforating gun attached to the wiper plug. The plug is forced downward pulling the perforating gun along. The downward motion of the plug in turn pushes the cement out the bottom end of the casing and into the annulus. The cement in the annulus is allowed to set and the perforating gun is activated.

摘要： A method of completing a wellbore that includes providing wellbore casing having shaped charges and permanent pressure gauges on an outer surface of the casing. In an example of use, the casing is inserted into the wellbore and cement is injected into an annulus formed between the casing and wellbore. The shaped charges are strategically deployed on the casing so they aim towards a wall of the wellbore and are spaced apart along the casing. Thus detonating the shaped charges creates perforations into a formation around the wellbore and places the pressure gauges into pressure communication with the formation. Pressure readings are delivered to the surface from the pressure gauges in the form of signals.
摘要翻译： 一种完成井筒的方法，其包括在壳体的外表面上提供具有成形装料和永久压力计的井眼套管。 在使用的示例中，将壳体插入井眼中，并且将水泥注入形成在壳体和井筒之间的环形空间中。 成形的装料战略性地部署在壳体上，因此它们朝向井眼的壁并且沿着壳体间隔开。 因此引爆成形的电荷会在井筒周围的地层中产生穿孔，并将压力表与地层压力连通。 压力读数以信号的形式从压力表输送到表面。
