OIL WELL CEMENT and ADDITIVES


Unique Drilling Fluids is fascinated with cement, cement additives and their resulting slurries. The complex chemistry of cement is for lack of a better word a mystery. Obviously there are theory's with respect  to its structure but any field or lab cement chemist can tell you that cement has a mind of its own. Some call it a living organism for it is continuously changing.  Our CEO is partial to cement and their additives and has integrated his knowldege and insight into the company's product portfolio. Our reseach extends to the cementing sector and our cost-effective cementing chemicals are of high quality. We encourage and participate in cement projects all over the world. We are presently working with companies in countries such as India (New Delhi), Libya (Tripoli), Mexico, Yemen, USA, Dubai and are excited about new developments and the projected growth of cementing and its affiliated applications. We are also co-inventors on an unconventional cementing philosphy which attacks the cement at the atomic monolayer and will give us better control over its random behavoir. This idea is patentable, publishable and will hopefully simplify applications and gives us safer and more predictable results. Our philosophy when it comes to slurry designs and additives, is to optimize the slurry's effectiveness while using the minimum concentration in regards to additives. Hence, obtaining a very intelligent slurry design inexpensively. This can only be done through research and development.



SLUR-TROL-HP-A Specially Designed High Temperature Cement Slurry System

This high performance slurry design is specific for high temperature wells that suffer excessive fluid loss and gas migrating problems. We generally advise or formulate our slurry's based on clients data and or complaints in regards to the current environment and product combination that they use. They come to us to not only supply products but to help fix their problems. Obviously this combination differs with respect temperature and pressure but we generally recommend this system for troublesome high temperature wells. CFL-UQ4 is a unique blend of  synthetic polymeric material, that provides filtration control for extreme temperatures and demanding environments. CD-U9L is the liquid equivalent to our high temperature dispersant and also provides an adequate amount of filtration control for our SLUR-TROL-HP system. CSB-LA-2 is a multifunctional cement additive. It is an effective anti-gas migrating agent, fluid loss additive, bonding agent, matrix intensifier, elasticity improver and also a corrosion inhibitor. CSB-LA is our neat gas migrating agenting lacking the stabilizer and ideal for certain situations. Together with CR-Q10-L, a high temperature liquid retarder, good fluid loss and a pumpable slurry is obtained. Density modifiers (light weight slurries or weighting agents are used to optimize the clients desired  density requirements. UDF never take short cuts and release products unless they have been carefully tested and proven under simulated conditions pertinent to the clients request and well needs. We tailor design slurry's according to your cement program and well  requirements. Hence, Giving The Well What It Needs!"  Please Contact Unique's Technical Division to inquire about products and services.
