| 121 | GUIDED LOCKING RAM BLOCKS | US15629522 | 2017-06-21 | US20170362911A1 | 2017-12-21 | Herbert Jay Read; Mark F. Alley |
| A ram block assembly enables a very high shearing, breaking, or parting force by utilizing guide rails and passageways within the ram block assembly to accept the rails and gird the rails against deviation from intended trajectory. The ram block rails and cavities enable application of extreme forces, opposing and concentrated within a small area, when actuating the ram block assemblies into the “open” or “close” positions. The ram block assemblies move in opposition, approaching each other and applying opposing forces against any material positioned between the ram block assemblies, and deforming, severing, breaking, shearing, parting, tearing and/or cutting, as the case may be, any said material positioned between the ram block assemblies. The severing of materials in the wellbore is known as “shearing,” and the apparatus performing this shearing operation as shear rams, shear ram blocks, shear blocks or shears. | ||||||
| 122 | Method For Recovering Tubular Structures From A Well And A Downhole Tool String | US15536489 | 2015-12-15 | US20170328160A1 | 2017-11-16 | Georges Emile Arnaly |
| This invention relates to a method for recovering a tubular structure (3) from a well (1), wherein a so-called free point is defined as the location where the tubular structure is stuck in the well. The method comprising providing a downhole tool string comprising a pipe-severing tool and an upper part of the downhole tool string; lowering the downhole tool string into the tubular structure to release the free pipe. Before the step of triggering the pipe-severing tool to sever the tubular structure, the method includes releasing the pipe-severing tool and subsequent withdrawing the upper part, of the downhole tool string away from the free point towards the surface over at least a predefined distance. The invention relates to a downhole tool string for use in such method. | ||||||

| An apparatus is used in cementing and perforating casing in a borehole. A cement head disposed on the casing has first and second containers. A first plug positioned in the first container deploys from the cement head in the casing in advance of cement slurry. An assembly positioned in the second container deploys from the cement head in the casing after the cement slurry. The first plug lands on a float collar on the casing, and a breachable passage in the first plug opens and allows the cement slurry to pass into the borehole annulus. The assembly has a wiper and has one or more charges. The wiper wipes the casing as the assembly is displaced down the casing with displacing fluid. Eventually, the assembly lands at the first plug, and hydraulic pressure applied in the casing activates the one or more charges to perforate the casing. | ||||||
