Background

A client was having challenges with successfully isolating high water concentration zones using swell packers in their infill wells in an offshore field in Canada. It is believed that the high water concentration was a result of near-by water injectors breaking through via high permeability zones and faults. The client approached Welltec® regarding this challenge, and a solution was developed with a high level of collaboration between Welltec sales, manufacturing, and operations.

Operation

Initially 2 x 812WAB5:5 were successfully installed the 1st of 2 wells for water breakthrough isolation and a further 5 x 812WABs were successfully installed in a further well.

Achievement

Incoporation of the Welltec Annular Barrier® (WAB), as a robust, rapid set alternate to the previously failed swells, lead to a significant reduction in water cut and an Increase in production.
Furthermore the lead time for initial supply was very short (1 month). As Welltec were able to provide a timely and superior WAB solution, this was another added value differentiation, that drove the client to work with Welltec Completions.

WAB® open hole zonal Isolation maximizes production, reduces water-cut, and eliminates risk and uncertainty associated with swell packers while making more efficient use of CAPEX.
