Hydraulic pipe
recovery tool
Churchill Drilling Tools, a provider of dart activated drilling
tools, has launched the HyPR™ (hydraulic pipe recovery)
system for the rapid recovery of stuck pipe. The tool can cut
the cost of stuck pipe situations by enabling operators to get
back on track more quickly.
HyPR, claimed to be the world’s first hydraulic pipe recovery
tool, was premiered at the Deepwater Operations Exhibition in
Galveston, Texas, USA, in November. The tool was developed
following extensive collaboration between Churchill Drilling
Tools and deepwater and Gulf of Mexico drilling teams.
When drilling challenging wells, stuck pipe situations can be
a costly interruption, incurring mobilisation wait times and
uncertain recovery attempts and delays.
The HyPR tool offers a simple method to quickly recover the
drill pipe and to begin side-tracking straight away. It also
delivers a clean cut for operators wanting to maximise BHA
recovery options.
Churchill Drilling Tools director Mike Churchill said, “Churchill
has already forged a strong reputation in the Gulf of
Mexico, where our dart technology has been recognised
for its versatility, capability and reliability in challenging
environments. What is exciting for the company is that the
HyPR system is the first product conceived and developed
specifically for the GOM market and we are expecting it to
deliver significant time savings for operators in the region.”
The HyPR system consists of a robust full-strength sub,
strategically positioned in the drill string. It is severed in
around an hour by launching and pumping through a HyPR
jetting dart, which lands inside the sub. The dart takes only
a few minutes to arrive and, with a relatively short period of
pumping, will part easily under a small loading, simultaneously
producing a perfect fish-neck for subsequent operations.
The expected mode of use is to set a kick-off plug, before
coming out of hole with the recovered pipe. However, the
system also provides jarring and internal wireline access for
further recovery operations.
The tool is available in a range of sizes and connections
to suit any drill string configuration. It is a natural partner
to Churchill’s DAV™ (dart activated valve), which can be
positioned below to allow circulation to first be regained in
pack-off situations. It is also compatible with a wide range
of drilling jars.
The system contains no explosives or high energy sources,
and no specialist equipment or personnel are required. It is
particularly useful in expensive or remote locations where
external assistance is more costly to mobilise.
