From 0 to 1,200 with SAS Breaker

The story you know - Well Performance

When it comes to well performance every story starts the same. An operator in Nigeria approached us with a well drilled in 1992 using water based mud and with a current production of 0 bbl/day. Over the years production had gradually declined until finally oil flow stopped entirely. The oil for this particular well was quite heavy at 16 API and gas lifts and acid treatments had all come to nothing.

The story we want - Well Stimulation

We love ourselves a challenge and a non-producing well where the competition has not had any results is almost too good a challenge to ignore.

And so the SAS Breaker 162B was called into action. This microemulsion product has shown itself effective around the world from India to the North Sea and the Middle East. This time Nigeria was the destination for the SAS Breaker 162B.

The well itself was a vertical in sandstone. Using a coiled tubing unit the product was placed in the well and left to soak. It restored the near-wellbore permeability by completely removing the near wellbore damage and water-wetting the sand grains.

After the soak period both strings were opened. The short string production increase from 0 Bopd to 450 Bopd (without gas lift), while the long string production increased from 0 Bopd to 750 Bopd (with gas lift). Both strings have 0% BSW.

A completely dead well was revived and brought back to life producing 1,200 barrels of quality oil per day. Not bad for a happy ending!
