  • Cement slurry fluidlosscontrol additives (FLAs) PetroWiki

    · FLAs are, therefore, used to prevent solids segregation during placement, and to control the rate of fluid leakoff in the static state Factors affecting the use of fluidlosscontrol additives (FLA) Neat cement slurries normally exhibit an uncontrolled API fluid loss of at least 1,500 cm 3 /30 min This value is excessive for most cementingDeepFXL additive: A single additive to provide fluidloss control and shorten transition time to help address shallow water flow concerns HALADVANCE™ 344 Cement Additive Innovative liquid additive to control fluid loss with low concentrations in fresh water, brines, andFluid Loss Additives HalliburtonFluid loss additives reduce water loss through the cement filter cake, which makes them especially useful in squeeze cementing The Polytrol ® FL line of products are effective fluid loss control chemicals for use in differing conditions and requirements, such as high temperatures and high salt concentrations Polytrol ® FL 29 is a dispersing fluid loss additive For primary or squeezeFluid Loss Control Additives BASF

  • Fluid Loss Additives / Cementing Additives by Al Moghera

    Cement Fluid Loss Control Additives Operators can confidently incorporate Al Moghera fluid loss additives into a cement system without adverse effect on thickening time or compressive strength When using these fluid loss additives, cement homogeneity and flow are retained Fluid loss additives also prevent formation damage by discouraging cement filtrate Experience these other advantages of· Action of cement fluid loss additives Two stages are considered with respect to the fluid loss behavior of a cement slurry : 1 a dynamic stage corresponding to placement and 2 a static stage, awaiting the setting of the cement During the first period, the slurry flow is eroding the filter cake as it is growing; thus a steady state, in which the filtration occurs through a cake of constantFluid loss additives ScienceDirectFluid Loss Control Additives Fluid loss control additives are added to cement slurries for the following reasons: To reduce the possibility of dehydration opposite porous zones and consequently flash setting of the cement Loss of fluid from the slurry will result in increasing slurry viscosity and gradient and higher circulating pressuresCement Additives (function and definition) | Planning

  • Fluid Loss in cement slurries for oil well applications

    Most operators will accept fluid loss values below 200250 ml/30min as reasonable good fluid loss control, but for critical jobs like a narrow annulus liner or casing job across permeable hydrocarbon zones, they typically require fluid loss values below 50 or even 15 A basic 158 ppg cement slurry with no chemicals to improve fluid loss will usually have a fluid loss value higher than 1106· Thinking about the fluid loss test, there is always some cement slurry loss of filtrate (water from the cement) but as the test progresses the rate of filtration reduces with time This reduction is caused by the building of a filter cake, whose thickness depends on its own permeability So, to answer the question, fluid loss allows to keep the water in the cement because it builds a barrierA talk about API Fluid Loss Better Well Cementing for ALLcement additive fluid loss weight polymer Prior art date Legal status (The legal status is an assumption and is not a legal conclusion Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed) Expired Lifetime Application number US06/615,394 Inventor Charles George Richard R Gerke Current Assignee (The listed assigneesUSA Dispersant and fluid loss additives for oil
