• The BPS™ Maxx is designed for use in horizontal completions to establish injection of fluid at the toe without intervention. This feature eliminates the need for intervention using traditional tubing- conveyed perforating guns or wireline tractors as a means of gaining access to the formation at the toe. Eliminating intervention reduces cost and risks normally associated with these operations. Once activated, the high flow area of the BPS Maxx allows for greater injection rates to support plug-n-perf or frac sleeve operations.

    The BPS Maxx uses the same field proven technology used with our standard BPS Toe Initiation Sub (over 20,000 installations), but with approximately 3 times greater flow area than our standard offering. Larger flow areas mean less risk in plugging from debris left in the casing after cementing operations. The BPS Maxx is an integrated part of the production casing or liner and can be used in both cemented and uncemented applications. Full ID through the tool eliminates the need for special wiper plugs, thereby reducing operational risk and cost. The BPS Maxx is actuated by applying pressure from the surface of the well. BPS Maxx Toe Initiation Subs can be installed as a single toe port or in multiples to create a full stage cluster. The large diameter of the ports reduces friction pressures through the injection ports.
