Long-term zonal isolation issues with oilfield cement annuli commonly result from cyclic temperature and pressure loading during the lifetime of the well.

Gulf Operations has developed MaxSeal^® to penetrate areas previously inaccessible to conventional cement slurry, such as tight casing leaks, gravel packs, small fractures, channels, or microannuli.

Lost circulation is the partial or complete loss of drilling fluid and/or cement slurry to the formation during drilling or cementing operations or both.

Gulf Operations’ LossCure^® is a cross-linking polymer designed to cure loss of circulation and form a permanent seal.

In sandstone reservoirs, operators often face sand production problems due to the degradation of reservoir rock around the wellbore under high-velocity fluid flow. In many cases, the sand consists of fines which are not retained by stand-alone screens or gravel packs.

Gulf Operarions is developing SandBlock^® technology for sand consolidation that will reduce the production of sand, improves oil production, increasing the recovery factor and life of the oil wells.
