customerCHALLENGEWhile 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


customerCHALLENGECuring 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 may vary between operators


customerCHALLENGEThe risk of lost circulation become more prevalent when drilling formations with:

High Permeability

Natural Fractures

Low ECD Margins (Induced Fractures)


STEELSEAL® Lost Circulation Material

Baroid’s SOLUTION

Highly resilient, dual composition carbon-based material

Background or Pill treatments

Deforms to stress in a multitude of fracture sizes

Increased material resiliency


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


Resiliency up to 120% Compatible in oil-, water-, and

synthetic based fluids High concentrations used with no

adverse effects to drilling performance

Increased lubricity in WBM Non-magnetic material

Will not effect downhole logging tools

key FEATURES

Typical Graphite STEELSEAL®


customer BENEFITS Cost Effective

– Reduce fluid loss and NPT with improved fracture sealing– Can be used as pre-treatment to prevent seepage– Increased ROP

Increased Drilling Performance– Improved fracture plugging, effective in HP/HT wells– Increase lubricity in water-based fluids, reduced torque and drag– No adverse effects to drilling equipment or rheological properties

Versatile – Deform to stress in multitude of fracture sizes– Effective in HP/HT wells– Specifically designed particle size distribution


STEELSEAL® Engineered, Specialty Lost Circulation Material

A highly resilient lost circulation material that gives operators a technically superior solution to mitigate seepage, partial or severe fluid loss rates, preventing non-productive time and saving money.

value PROPOSITION


CASE STUDY: STEELSEAL® LCM and BARACARB® bridging agent help Apache improve wellbore stability and cut costs by 50%

Location: Neuquén, Argentina

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.

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.

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

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

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

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
