E21B 43/017
PCT/NO2016/050160JB SERVICES ASHAUGSTAD BAKKEN, Jan Narve
There is described a method and related apparatus for transporting fluid from a well (3) and supplying the fluid into a production header (12). The fluid may be transported through a path (19) between the well and the production header. At least one pump (20) may be provided at a location along the path to drive the fluid along the path. The pump may be operated to apply a vacuum or partial vacuum in the path to allow the fluid to travel along the path from the well to supply the fluid to the production header, e.g. for starting up a well.

6. WO/2017/007329 EQUIPMENT FOR CONTINUOUS OR SEMI-CONTINUOUS CASTING OF METAL WITH IMPROVED METAL FILLING ARRANGEMENTWO12.01.2017
B22D 11/103
PCT/NO2016/000017NORSK HYDRO ASARøen, Geir Atle
An apparatus (1) for continuous or semi-continuous low pressure casting of metal, in particular directly-cooled (DC) casting of extended objects such as a rods, bars or billets (25) of aluminium. The apparatus includes a frame construction with at least one chill or mould (3) having a mould cavity that is provided with an upwardly open inlet (4) and an outlet with cooling means. The inlet of the mould is connected to a distribution chamber (5) receiving liquid metal from a metal store such as a holding furnace via a metal supply channel or launder (6). A flexible launder section (28) is provided between the launder (6) and the metal distribution chamber (5) whereby the frame construction with the moulds (3) and distribution chamber can be raised and lowered to enable complete filling of metal to the moulds. Subsequently it is possible to control the metal level in each respective mould cavity in relation to the metal level in the launder and thereby controlling the low pressure casting.

7. WO/2017/007330 MECHANICAL TREATMENT SYSTEM FOR SLOP WATER AND METHOD FOR USE OF SAMEWO12.01.2017
E21B 21/06
PCT/NO2016/050137SOILTECH ASBERGSVIK, Oluf
A treatment system (1) for slop water is described, the treatment system (1) comprising : - a decanter (2) including at least an inlet (21) for the slop water which is to be purified and an outlet (22) for a water phase, - a separator (4) connected to the decanter (2) downstream thereof; and - an analyser (3) including an analyser unit (31) placed upstream of the inlet (21) of the decanter (2) of the treatment system (1) for determining the solids and oil content of the slop water. What is characteristic of the treatment system (1) is that the analyser (3) of the treatment system (1) further includes a second analyser unit (32) downstream of the decanter (2) for analysing the water phase coming out therefrom; and that said analysis of said water phase determines: - whether the water phase will be returned for re-purification in the decanter (2); or - whether the water phase will be passed on to the separator (4), and in that case the settings thereof.
