The Cameron Time Saver Wellhead System
is a conventional two-string wellhead system with
specialized features to enhance safety and reduce instal-
lation times. This system is ideally suited for drilling out
and running the surface and production casing strings
with a conventional drilling rig, then subsequently
fracturing the well and completing it with a smaller
completion and workover unit.
System Design Features
Safety The need for hammer wrenches for BOP and
tubing spool nipple up is eliminated with the use of a
simple union nut, requiring fewer personnel and less
time spent under the rig floor. What used to be a two-
man operation requiring two hours or more can be
accomplished in minutes with a single person using a
purpose-built spanner wrench. Another safety
enhancing feature is the special Time Saver frac
mandrel. This tool is used to isolate the tubing spool
outlets and top flange during well stimulation. Using
this piece of equipment in conjunction with a high
pressure frac tree, frac pressures of up to 10,000 psi
can be safely achieved in a 3000 or 5000 psi wellhead.

rotary table. Once landed, casing can then be cemented
and the running package retrieved, allowing rig opera-
tions to continue without waiting on cement. This saves
time when compared to conventional flanged wellheads
which often require several hours of waiting on cement
prior to installation of the casing head, which then must
be welded requiring more non-productive rig time.
In addition, the casing head is sized to allow
clearance for a 1.0” line to be run in the event that
remedial cementing at the surface is required. An
optional mandrel casing hanger is available for the
production casing. This hanger eliminates the need
to wait on cement and nipple down the BOP prior to
hanging off the pipe in the casing head. A retrievable
packoff is used to isolate the annulus after the hanger
has been run.
Versatility The Time Saver wellhead is available in
3000, 5000 and 10,000 psi working pressures,
and uses standard bowl preps for casing and
tubing hangers. The wellhead may be used
with either slip-type or mandrel type casing
hangers. The mandrel hanger is fluted which
allows for taking cement returns through the BOP stack
rather than through the casing head outlets, making this
one of the most versatile wellheads while saving time.

Tubing Spool Available with a 7-1/16”3000 psi or 5000 psi flanged top or a 4-1/16” 10,000 psi flanged top. Bottompreparation is available in sizes from 4-1/2” up to 7” casing. Outlets arethreaded or studded depending uponoperator preference.
Frac Mandrel The frac mandrel israted to 10,000 psi and can bepre-installed in the tubing spoolor on the frac tree, saving timeonce out in the field.
Casing Head Available with 5000 psi rating and a standard 11” Cameron IC-2 bowl. Typical bottom preparations are API female threaded connections.
Casing Hangers Standard Cameron IC-2 slip-type hangers are available, or a fluted mandrel hanger with aretrievable pack off may be used.
The Time Saver Wellhead is easily converted from production mode
to frac mode.
Union Nut Allows easy installation andremoval of BOP adapter, production treeand frac mandrel.
