CHALLENGE
While an effective wellbore strengthening program is your best
defense against lost circulation, complete prevention is not
always possible. The lack a well thought-out remediation plan for
lost circulation could cause:
 Increased Non-Productive Time
 Decreased Wellbore Value
 Heath and Safety Issues

CHALLENGE
Curing lost circulation becomes more difficult based on
formation type and rate of fluid loss
 Classifications of Fluid Loss*
 Seepage: <10 bbl/hr
 Partial: 10-50 bbl/hr
 Severe: 50-100 bbl/hr
 Total: >100 bbl/hr – no returns
*The range for each classification
vary between operators

Baroid’s
SOLUTION
STEELSEAL® lost circulation material
has a resiliency which allows it to “mold”
itself to all stress regimes within any
fracture, promoting fracturing plugging,
and providing superior sealing

Resiliency up to 120%
 Similar materials show resiliency of <40%

Highly effective in HP/HT environments

Constant and effective fracture sealing in
turbulent down hole conditions

CASE STUDY: STEELSEAL® LCM and BARACARB® bridging
agent help Apache improve wellbore stability and cut costs by 50%
Location: Neuquén, Argentina
CHALLENGE


At 1,800 m measured depth (MD), a short trip was initiated to the conductor shoe at 400 m. After the trip,
wellbore instability and excessive cuttings prevented a return to bottom.
Significant non-productive time (NPT) and costs were associated with stuck pipe, casing issues and additional
trips to condition the wellbore.
SOLUTION


Baroid personnel recommended an engineered WBM formulation
To address wellbore instability issues, the system was further customized with STEELSEAL® Lost Circulation
Material and BARACARB® Bridging Agent additions to seal microfractures and strengthen the formation during
drilling operations.
RESULTS

Based on total rig costs, the Apache Corporation was able to save USD $1.15 million on the well drilled with
the engineered fluid recommended by Baroid

The actual mud costs for the Baroid fluid were also 9% lower than planned.

CASE STUDY: STEELSEAL® LCM sweeps help avoid downhole
losses while drilling depleted zone in surface interval
Location: Texularia Sand/Muscar Field, Venezuela
CHALLENGE



PDVSA planned to drill through the Textularia sand in the La Pica formation, a severely depleted zone in the
surface interval of the MUC-123 well
Previous offset wells in the Muscar field encountered severe lost returns and stuck pipe while drilling the 17-1/2”
surface section
The challenge was to provide an engineered fluid solution that would permit the operator to drill the 17-1/2” hole
in a safe and timely manner and set surface casing to total depth without further occurrences of lost circulation
SOLUTION


Baroid engineers recommended implementing an LCM sweep program when approaching the depleted sand to seal
off the sand and prevent or minimize losses
The unique STEELSEAL® lost circulation was used because of its ability to expand or contract without being dislodged
by changes in differential pressure
RESULTS
 The successful application of the STEELSEAL® LCM sweep pills combination allowed PDVSA to avoid costly
remedial operations and eliminate non-productive time (NPT)
 The offset wells was drilled with zero NPT, saving $160,000 in fluid costs compared to the previous
Muscar wells
