Challenge: Place barriers to isolate formations from each other and from the
surface
 Appropriate selection of materials and elements to form the barrier(s)
 30 CFR part 250 – pg 263-264 describes cement
 UK Oil & Gas describes alternative materials
 Individual operator requirements generally more stringent
 Key parameters
 Permeability
 Fluid interaction
 Dimensional stability
 Mechanical properties
 Other (material dependent)

Solution: Resin (WellLock® Resin) and Resin/Cement Composites (LockCem™
Cement)
 WellLock® Resin usage in abandonment operations
 LockCem™ Cement usage in abandonment operations

Halliburton Resin Usage Recommendation for Plugging
 Job designs using the lowest volume of resin to achieve maximum results is
recommended to be employed.
 The length of the resin portion of the plug is recommended to be no more than 20% of
the total plug length, while the remaining 80% of the total plug length is recommended to
be a Portland-based cement, composite cement (LockCem™ Cement) or equivalent.
 If a leak is located, it is recommended to contact the leak pathway with the resin and to
squeeze the resin into the leak pathway as part of the job procedure.

Resin Cement Composite Case Study
Challenge

Rig less abandonment, no cementing equipment, only wireline

Small slurry volumes (2.5 to 5 bbls total)

Abandon bottom part of well and perforate new intervals in close proximity
Solution

Dump bailer run on wireline used to place slurry on top of mechanical base

Small volumes mixed using hand mixer

Resin cement composite system (20% resin and 80% cement by volume)
Results


Dump bailer minimized contamination of small volume in specialized applications

Increased shear bond of LockCem™ Cement allowed shorter plugs

Plug length ranged from 100 to 200 feet

100% success rate on all wells
