X-TRA Seal R is advanced self-sealing product were designed for production and non-production zone and both low and high permeability formations according to last global technologies. It is defined as a best new efficient product for drilling in high differential pressure conditions, multi-pressure zone permeable and weak formations.
X-TRA Seal R (LPM Product)
X-Tra Seal R form a thin film on the surface of formation/fracture and sael it. the mechanism used for sealing is inherent in the individual particles used to form the seal. Natural polymers that are activated in all drilling fluids provide the seal between particles. The mechanism used in forming the structure is more conventional in that it uses a high fluid depletion rate to collapse the fluid structure of the pill and rapidly form a seal by creating a bridging mat across a permeable zone, which then rapidly builds into a seal. this product prevents the formation of a thick filter cake while drilling through pressure depleted formations, minimizes if not completely avoids the likelihood of differential sticking imparts borehole stability and stabilizes shale by preventing filtrate invasion into permeable structures.
X-TRA Seal R is easily applied as a one-sack product and creates an effective pressure seal at significantly lower concentrations than is normal for these applications.
