Gravel packs are placed in the screen-casing annulus across perforated intervals and in perforation tunnels to prevent the production of formation fines and sand. Frac packing—our STIMPAC service—combines gravel packing with fracturing, creating wide, highly conductive fractures connecting the reservoir to the wellbore.
Alternate Path technology includes shunt tubes and nozzles used on screens to bypass bridges and fill in voids. It is compatible with most gravel- and frac-pack systems.
Single-zone gravel and frac packing can be performed by a conventional system requiring multiple trips or by a more efficient system in a single trip.
In complex reservoirs, multiple zones can be isolated and treated independently or in a single pumping operation, with either commingled or selective production, using a range of technologies, including The MZ-Xpress system for performing multizone fracturing and gravel packing in a single trip.
