Overview
Because of logistical delays for permitting, transporting, and storing
explosives, an operator in Indonesia sought a way to mitigate the risks
and costs associated with using explosives to punch and cut tubing for
a plug and abandonment (P&A) operation. Deck space was limited on
the proposed vessel so Halliburton recommended an integrated
cased-hole (ICH) combo unit capable of performing multiple
intervention solutions using slickline, electric line, and fishing.
A service package was proposed that included nonexplosive pipe
recovery solutions to cut and punch the tubing. Halliburton’s unique
integrated solution helped the operator to improve job efficiency,
reduce HSE exposure, and minimize overall operating expenses.
By integrating multiple intervention solutions into
a single unit, the customer was able to minimize
risks and costs on its deepwater project located
offshore Indonesia.
CHALLENGES
SOLUTIONS
RESULTS
Mitigate costs and risks associated
with explosives
Using explosives for the P&A
operation would require logistical
delays for permitting, transporting,
and storing explosives.
Halliburton proposed nonexplosive
approach
A service package was recommended
that included nonexplosive pipe
recovery solutions to cut and punch
the tubing.
Safety risks and expenditures minimized
The use of a nonexplosive approach
to punch and cut the tubing eliminated
the need for explosive permits,
explosive security escorts, and costly
transportation of explosive materials.
Required both slickline and electric
lines for operations
This P&A operation needed electric
line and slickline for the first phase
of the operation. Deck space was
limited so the operator needed a way
to accomplish both services with a
limited footprint.
Integrated cased-hole combo unit
saves space and money
Halliburton suggested a unique ICH
combination unit. Slickline, electric
line, and fishing could all be performed
efficiently from this single unit.
Decreased expenses a result of
simplified logistics
The space-saving combo unit was
able to perform all the necessary
services and required only one crew
vs two, lowering transportation and
change-out costs, bed space, and
daily crew rates.

CASE STUDY: Unique integrated solution offers safer way to minimize operating costs
Unique integrated cased-hole unit efficiently and safely addresses P&A project needs
An Indonesian operator needed a way to mitigate the risks and costs associated with using explosives to punch and cut tubing
for a P&A operation. This was due to logistical delays for permitting, transporting, and storing explosives. The P&A operation
required the services of both electric line and slickline to perform the first phase of the operation. Due to the deck space on the
proposed vessel, the operator needed a way to accomplish both services with a limited footprint.
Halliburton proposed an integrated cased-hole combo unit to perform multiple intervention solutions using slickline, electric
line, and fishing from a single unit. For nonexplosive challenges, Halliburton proposed a service package that included
nonexplosive pipe recovery solutions to cut and punch the tubing without the use of explosives.
The combination of slickline/electric-line unit reduced personnel on board and eliminated changing between electric-line and
slickline units. The P&A project was performed with one integrated crew instead of separate slickline and electric-line crews.
The logistics were simplified during crew change, which also led to savings on transportation, bed space, and daily crew rates.
Logistics and transportation costs of both the electric-line unit and slickline unit were reduced to a single transportation cost.
A single dual-purpose pressure control equipment (PCE) configuration simplified the services performed by slickline/electric
line. The nonexplosive approach to punch and cut the tubing eliminated the need for explosive permits, explosive security
escorts, costly transportation of explosive materials, and possible time delays. The ability to combine technologies enabled
Halliburton to create a unique integrated solution, which in return improved job efficiency, reduced HSE exposure, and
minimized overall operating expenses.
