Case History: Scale and Paraffin


Date: -


Location:

Gulf Mexico, West Texas, South Texas and Colorado

Formation:

Miocene, Wolfberry, Eagle Ford Shale and Williams Fork-Cameo

Treatment:

The solid scale and paraffin inhibitor were place down hole in the fracture fluid with the sand. The product is nominally within the mesh size of 20/40 proppant. When the well begins to produce, the scale and paraffin inhibitor is slowly desorbs into the water phase of the production, inhibiting the disposition in the near-well bore area and tubing.

Results:

A Gulf of Mexico operator wanted to treat an Asphaltene problem down hole. A solid paraffin inhibitor was used to treat the formation. After 6 months, the well was producing oil and no production problem associated with Asphaltene plugging or disposition.

A West Texas operator was experiencing declining production rates due to scale problem. A solid scale inhibitor was used to treat the formation. The operator has treated more than 120 wells and continues to treat eight wells per month. The longest standing treatments have provided more than 2 years of intervention protection. According to the operator the only intervention has been to replace a single rod pump and parts and no scale was found on the down hole equipment.

A South Texas operator was experiencing paraffin deposition. A solid paraffin inhibitor was used to treat the formation. The operator specified that the treatment life must exceed 6 months, be economical and ultimately increase production. A six well field trail was completed with no remediation required after 55,000 barrels of oil were produced.

A Colorado operator was interested in an approach to treating scale and corrosion problem down hole. A solid scale and corrosion inhibitor was used to treat the formation. In the 10 months since the treatment no corrosion or scale related failure have been reported. The customer has reduced expense related to lost production, downtime and rig work.
