Innovative liquid additive to control fluid loss with low concentrations in fresh water, brines, and seawater with effectiveness up to 400°F (204°C). There are following 10 types of additives of cementing: accelerator, retarder, defoaming agent, drag reduction agent (dispersant), fluid loss additives, anti-gas migration agent, spacer fluid, latex, reinforcing agent and weighting agent. Properties Suppliers. The wide-temperature-range additive, part of the UNIFLAC universal fluid-loss additive system, is a custom-made liquid polymer that is less sensitive to small temperature or concentration variations. In a wellbore annulus, fluid can be displaced from the slurry while it is passing though constricted areas, or to the formation, resulting in an increase in the equivalent circulating density (ECD), which can lead to formation fracture (lost circulation) or flash set (dehydration). On 30 th May 2020, BASF SE, a key player in the chemical industry, has confirmed that it plans to start its smart Verbund project in Zhanjiang, Guangdong.The first plants would manufacture engineering plastics and thermoplastic polyurethane to meet the increasing needs of diverse growth industries in the market across Southern China and across Asia. additives methods control fluid cement slurry fluid loss Prior art date 1990-07-31 Legal status (The legal status is an assumption and is not a legal conclusion.
