A hydrocyclone separator for separating oil from water includes a substantially cylindrical first portion with a central overflow outlet and at least one tangential flow inlet, at least one converging section, and a tail portion with a central underflow outlet having a substantial length thereof characterized by a slight taper in the range of 1 to less than 15 degree-minutes.

A hydrocyclone separator for separating oil from water includes a substantially cylindrical first portion with a central overflow outlet and at least one tangential flow inlet, an essentially single angled conical second portion, and a substantially cylindrical third portion, with a central underflow outlet. The hydrocyclone separator is made in accordance with the following relationships:

Hydrocyclone separator

A hydrocyclone separation system is disclosed for separating a fluid mixture into at least two separate density components and for precluding remixing of semi-separated higher density components. A first and second hydrocyclone separators each has a central overflow outlet, a tangential fluid inlet, and a central overflow outlet. The first and second hydrocyclone separators are oppositely disposed such that a curved flow direction conduit extends from the underflow outlet of the first hydrocyclone separator to the tangential fluid inlet of the second hydrocyclone separator. Thereby, rotating fluid exiting the underflow of the first hydrocyclone separator is tangentially passed into the inlet of the second hydrocyclone separator precluding remixing of semi-separated higher density components and increasing the overall separation efficiency of the system.

A releasing tool for use in disconnecting a casing or conductor pipe cemented below the marine floor from a riser pipe supported from a floating vessel in which the riser pipe and conductor are held together by a snap ring. This includes cam carrier connectable to the lower end of a longitudinal member, such as a drill pipe, and a releasing pin block carrying radially supported releasing pins which are urged inwardly. When the cam of the cam carrier is urged downwardly with respect to the releasing pin block it forces the releasing pins outwardly through ports in the latch pin of the casing to release the split rings from its engaging position.

A scissored sea-floor well template for positioning spacing of subsea wells or piling in the sea floor. Two arms, each having a pontoon template at each end thereof, are pivotally connected. The two arms are rotated about the pivot to a closed position for transportation to the marine site at which they are to be used. Inasmuch as the template is provided with pontoons, it can be towed and does not have to be loaded on a barge although it could be. Upon reaching the well site the arms are opened so that the pontoon templates assume the desired shape. The arms are then locked in this extended position and the scissor well template is then lowered to the ocean floor.
