Dajan Srl is an UNI EN ISO 9001:2004 and UNI EN ISO 14001 certified service company. Its service core business is mainly based on slick-line, wire-line and coiled tubing related operations.

Slick-line:These activities allow the lowering and / or retrieving tools in a alive well (under pressure) through the use of a special steel wire (harmonic) with a diameter of 0.108 "- 0.125" - 0.140 ". The tools run can be instruments for measuring well data (i.e. pressure and temperature), for manipulation of well components (safety valves, circulation valves, plugs, etc.) or for well intervention (i.e. fishing operation).The tool string (composed of fishing neck + stem weight bars + tool specific for the operation to be performed) is connected to the wire after it has been passed through the stuffing box and then inserted in the lubricator; all is raised and connected to the BOP on top of the wellhead. At this point, the well can be opened and the operation carried out in the conditions of maximum safety.

Wire-line: It uses a mono-conductor electrical cable with an outer armature of 5 - 6 millimeters diameter which creates a pathway for electrical telemetry and communication between the surface and the equipment at the end of the cable. The Well Head Equipment is the same as the Slickline one if not for the stuffing box that in this case becomes a flow-tube as the hydraulic seal on the 'rough' surface of the armored cable is achieved by injecting special grease (sealing). The electric-line is used in all those operations in which continuous monitoring is required like production logging, well pressure build up in SRO, video camera as well as of well intervention and pipe recovery operations.

Coiled tubing: it is a continuous tube of steel (coiled tubing) usually with diameter from 1 inch to 1.5 inches. Dajan offers instead a light version with diameters starting from ¼ ". This tube is wound on a drum driven by a suitable hydraulic power unit. The hydraulic seal on the tube is carried out using the appropriate stuffing box (stripper); the presence of a lubricator (riser / s) and a BOP is required to allow the release and recovery of the equipment from the well while a special injection head serves for the movement of the tube into / out from the well. The coiled tubing allows to move and then to perform a variety of tasks such as: washing, facelift, injection of chemicals, acid treatments, cementing and, if equipped with appropriate equipment also Housekeeping and millings.
