| 201 | METHOD AND SYSTEM FOR ENABLING ACQUISITION OF BOREHOLE SURVEY DATA AND CORE ORIENTATION DATA | EP17743487.5 | 2017-01-23 | EP3408492A1 | 2018-12-05 | MCLEOD, Gavin; BROWN, Kelvin; JABBAL, Gertej Singh |
| A system (10) and method (50) of enabling the acquisition of borehole survey data and core orientation data in a single instrument trip in a core drill (12) having a drill string (18) and an inner core barrel assembly (16). The method uses a borehole survey tool 14 that is arranged to at least log its position in three-dimensional space. The borehole survey tool (14) is run down the drill string (12) in which the inner core barrel assembly (16) is installed. The inner core barrel assembly (16) is arranged to either provide or facilitate detection of an indication of tool face of a core sample (24) held in the inner core barrel assembly (16). The indication of tool face is then transferred mechanically or electronically to the visiting borehole survey tool (14). | ||||||

| A head assembly includes a body, a spearhead operatively associated with the body and configured to translate axially relative to the body, and at least one latch operatively associated with the spearhead and the body. The latch is configured to move between an extended position and a retracted position relative to the body in response to axial translation of the spearhead relative to the body. In an extended position, the latch covers more than 25% of the circumference of the body adjacent the latches. | ||||||
| 203 | FLOAT VALVE SUB | EP16827823.2 | 2016-07-21 | EP3327248A1 | 2018-05-30 | SHIMMOTO Yuichi; MIYAZAKI Eigou; AKIYAMA Keita; KAWAHARA Masaki; SUZUKI Tomoaki |
A recess that accepts a float valve cover, such as an extension, a ground-out portion, a cut-out portion, or the like, is formed inside an external cylinder assembly of a drill string. Thus, when the drill string is provided with a float valve, the inner diameter of the drill string can be expanded and a larger diameter core can be collected using a finer drill string. |

| 204 | PRESSURE CORING ASSEMBLY AND METHOD | EP12757038.0 | 2012-03-09 | EP2686515B1 | 2018-02-07 | KINSELLA, Doug |
| A wireline or drill pipe retrievable coring tool with an inner barrel to receive a core, a bottom coring tool valve operable to seal off a bottom of the inner barrel and at least one pressure canister operable to receive fluid from the core in the inner barrel.

| A latching system has a latch body, a latch carrier and two latch dogs. The latch dogs are retained in the latch carrier by two pins. The latch carrier is located within the latch body. The latch body has slots through which the latch dogs can extend. The pins pass through both latch dogs and through longitudinal slots in the latch carrier. The pins are fixed at their opposite ends to the latch body. When the latch carrier is moved axially the latch dogs move parallel to each other between: a latching position where the latch dogs extend from the latch body and latch carrier and can engage a latching mechanism; and a release position where the latch dogs retract inwardly. | ||||||
