FineCem™ Cement – Benefits
Benefits over Conventional Micro-Particle Slurries




Extremely low viscosity for pump-ability
Lower yield points
Enhanced free-water control
Improved stability

FineCem™ Cement – Features
 Excellent pumping properties due
to the ultrafine particle size
– Eliminates need for dispersants
or friction reducers
 Can be moved through the scale
tank of the bulk plant for easy
blending of additives
– Eliminates handling of sacks
in the field
– Simplifies field operations
– Improves safety
 Compatible with all cement
additives and does not require
dispersants

FineCem™ Cement – Tight Casing Leaks
 Remediation for tight casing
leaks that bleed off pressure
and will not accept a
continuous injection
 Can penetrate small leaks
 Repair without prior acid
treatment

FineCem™ Cement – Gravel Pack Breakthrough
 Remediating for undesired
water, gas or steam
production through
gravel pack
 Penetrates the permeability
of gravel packs
 Shuts off unwanted flow

FineCem™ Cement – Primary Cementing
 Lightweight cement
 Achieves early compressive
strengths higher than
conventional lightweight
slurries
– Temperature range from
110°F - 295°F (43°C -146°C),

FineCem™ Cement – From the Laboratory
Flows through the pore space typical of proppant used
in Shale gas fracture stimulation treatments

FineCem™ Cement – From the Field
 Challenge – Shale / Extended-Reach Horizontal
– Perforation would not accept proppant fluid even
under 8,500 psi pumping pressures
– Unable to complete aggressive completion
operation until perforation was sealed
– Time-consuming and expensive option: coiled tubing and snubbing
units brought in to place and set a mechanical tool
 Solution – Alternative: FineCem™ Cement squeeze operation
– Flow easily in highly-pressurized perforation (low rheologies)
– Highly stable slurry with low fluid loss
– Quickly achieves static gel strength, resisting gas channeling
 Results
– 105 feet of cement total above and below retainer
– Zonal isolation verified via successful casing pressure test
– Completion operations resumed and well brought on to production
soon after

FineCem™ Cement – From the Field
 Challenge – Offshore: achieve successful
temporary plug to abandon on first attempt
– Before setting cement plug, stop any
potential flow of formation fluids through
an existing gravel pack section
 Solution – FineCem™ Cement
– Squeeze operation through the screen at
the gravel pack zone using 50 bbl of
FineCem cement
– 50 ft cement plug was set above the
retainer
 Results – Well was successfully
abandoned

prior acid treatment and without
bridging off
 Gravel packs
– Penetrates the permeability to
shut off unwanted flow
 Slimhole conditions for primary
cementing
– Excellent pumping properties
– Achieves early compressive
strength
