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
