| 101 | Plugging a mined-through well | US13269455 | 2011-10-07 | US08727028B2 | 2014-05-20 | Rick D Johnson |
| A system and method of plugging a well bore includes intersecting a portion of a well with a subterranean cavern. A portion of the well may be isolated to prevent accumulation of reservoir fluids in the subterranean cavern by, for example, inserting a packer in the well to form a seal. A sealing material may be pumped into and allowed of solidify in the portion of the well to form a partition between the subterranean cavern and the remainder of the well. The formed partition permits continued production from the well and continued mining in the subterranean cavern. | ||||||
| 102 | Frac adapter for wellhead | US12937525 | 2009-04-29 | US08727020B2 | 2014-05-20 | Bradley Bertrand |
| There is provided a frac adapter configured to couple a frac tree to a wellhead component. The frac adapter may couple the frac tree to a casing head without a tubing head, thereby enabling the well to be fractured before the tubing head is installed. As a result, the tubing head used in well production may be pressure-rated for production pressures rather than for fracing pressures. The frac adapter may be coupled to or integral with the frac tree. In addition, a union-nut coupling may be employed to quickly and easily assemble and disassemble the frac adapter from the wellhead component, such as the casing head. The union-nut coupling may further enable the components to be pressure-tested before the fracturing process is initiated. | ||||||

| A method for placing ball sealers within a well formed within a subterranean formation for sealing holes in a casing of the well is carried out by performing at least one of two operations. The first operation involves providing a tag with at least one ball sealer or a carrier fluid containing the at least one ball sealer to facilitate monitoring of the location of the ball sealer. A tag monitoring device is provided within the well for monitoring the location of the tag. The ball sealer and carrier fluid with the tag are introduced downhole into the well. Information from the monitor device regarding the location of the tag is communicated to a remote monitoring location to the thereby provide an indication of the location of the tag within the well to a surface location. In the second operation a container is provided within the well at a known location downhole within the well. The container contains at least one ball sealer. The ball sealer or sealers are released from the container within the well at the known location in response to an instruction initiated from a surface location. | ||||||

| An apparatus and method is provided for stripping solids and fluids from a string used in the drilling or servicing of a well when the string is removed from the well. The apparatus can comprise two or more pivotally connected arcuate body portions that can be enclosed around the string in a clamshell fashion. The apparatus can further comprise a seal disposed therein to provide a toroidal sealing member around the string when the apparatus encloses the string. A quick release latch mechanism is provided on the apparatus for easy and quick installation on, and removal from, the string. Handles on the apparatus allow personnel to hold the apparatus in a stationary position as the string passes through the apparatus when being raised from the well. In so doing, the sealing member strips solids and fluids from the string. | ||||||

| A containment and protection system for wells in the oil and gas industry may solve the problem of crude oil, salt water and chemicals from absorbing into the ground and contaminating the ground, water and animals. The system may provide safety for landowners, workers and livestock. The system may attach around a wellhead and flowline. The system may be dug into the ground so that it is below the surface casing and then sealed and secured thereto. A lid of the system may close overtop of the well to make it secure and leak proof. The lid may also be insulated to hold in warmth, thereby reducing the need to insulate the wellhead. The system may provide safeguards that may shut down the pump driver or close valves to stop flow from the well and flowline under certain conditions. | ||||||

| 118 | SPLIT NON-WELDED CASING CAP FOR HIGH TEMPERATURE SERVICE | US12399805 | 2009-03-06 | US20090223661A1 | 2009-09-10 | Abram KHAZANOVICH; Irina Khazanovich |
| A casing cap to seal the annulus formed between an upper end of an outer casing and an inner casing. An annular casing cap housing is formed in split portions which when joined at their splits form the casing cap housing to cover and seal the annulus. The joined casing cap split portions form a side wall which surrounds the outer casing. The upper end forms an annular top section adapted to rest on the upper end of the outer casing, cover the annulus and form an upper annular seal to the inner casing. The lower end is adapted to form a mechanical connection, preferably non-welded, to the outer casing and to form an annular seal to the outer casing. Connectors between the casing cap split portions clamp together the sealing surfaces of the casing cap split portions with the sealing element to form pressure-containing, non-welded seals. | ||||||
