Rumba Solids Control System
The Rumba Solids Control System is the only efficient unit
available where high muci volumes and heavy gumbo concen-
trations are encountered as in the North Sea, Under these con-
ditions conventional shaker systems do not give the required ef-
ficiency. This new SCS system developed by Hutchison-Hayes
provides the necessary equipment to properly handle mud con-
ditioning when drilling large diameter surface hole in pure gum-
bo. During the surface drilling phase the primary solids
separator section is fitted with a perforated plate screen and is
intended to be used for gumbo removal. The gumbo is dis-
charged from the system via shale slides which are equipped
with high pressure water sprays to prevent build up of the gum-
bo, Presereened mud from the primary separator section is dis-
charged into the back tank of the secondary separator section.
The secondary section dual screen deck would be equipped
with a 20 x 20 mesh top and 40 x 40 mesh bottom screen. Thus
giving a 40 x 40 mesh cut at approximately 38 bbl, P.M. in sur-
face hole conditions, Additionally, incorporated in the unit is a by-pass system that allows the operator to use any
combination of screens required. For example, when the surface drilling phase is completed, it is possible to by-
pass the primary separator section and screen only on the secondary separator. The reverse is also possible. Should it
be necessary to change screens on the primary or secondary sections, drilling may continue as each section may be op-
erated independently.
Rumba SS101-102
The Rumba SS101 and 102 Solids Separators provide more solids removal
quickly through controlled elliptical motion of the screens. Amplitude and diree
{ion of this motion varies down the length of the screen to provide maximum
acceleration of solids particles away from the mud stream. In addition, the
adjustable oaskel slope of the 101/102 (from -13° to +3°) provides maximum
efficiency from surface to T.D.
The 101/102 is provided with air-mount basket suspension or with hard rubber
block mounts where temperature extremes preclude the use of air-rnounts,
