SAS Breaker Products Put to the Test in India

Our customer, based in Asia, was experiencing difficulty in meeting production expectations from new wells. They drilled using Oil Based Muds (OBM) in a heavy oil reservoir. They were using thermal stimulation in order to decrease the viscosity of the oil. However, no mud damage treatment had been used before activating the well and they were not producing the expected volumes. SAS Production Services knew that our products could help. 

The operator was aware that the drill-in fluid damage was significant and beyond the capabilities of their usual treatment methods. Many lab tests were conducted and the SAS Breaker products were a clear winner, outperforming the other potential solutions being considered.

SAS Breaker treatment fluid was used to dissolve and displace the OBM used to drill the wells. The operator decided to use remedial treatments based on displacing SAS Breaker for OBM fluid into the screens spanning the reservoir sections, using coiled tubing.

SAS Breaker products are a patented approach using unique microemulsions to mobilize hydrocarbons in the skin created by the OBM. SAS Breaker products can be combined with most available acids and acid precursor products. This aids to dissolve calcium carbonate that is often found in OBM and filtercake. The fluid was placed in each well using coiled tubing and left downhole for the required soak period. The wells were then returned to production.
