Jun 18, 1991· Fluid loss control additives for oil well cementing compositions . United States Patent . Abstract: A cementing composition useful in cementing oil, gas and water wells, comprising water, hydraulic cement and an effective amount of water soluble fluid loss additive comprised of a blend of a copolymer of acrylamide/vinyl imidazole in a ...
The effects of the additives are reduced or enhanced by modifying the additive or by using additional additives. For most downhole requirements, more than one additive is needed. This giveandtake relationship between additives is the basis of cementslurry design. Effects of additives
Dec 12, 2017· Hence, for a cement slurry you plan to use for example inside a casing, fluid loss is not a relevant factor in the design. Now, fluid loss property of a cement slurry is also connected to free water and stability of the slurry, so for a useful cement slurry even inside casing, good fluid loss (normally, meaning low) is indirectly a factor.
Fluid Loss Additive for Fresh Water Cement Slurries. Description. Fluid Loss Additive for Fresh Water Cement Slurries is acclaimed for its pure and effective composition. We offer this chemical in different grades and specifications to meet the diverse requirements of clients.
Jul 03, 2016· Cement slurries employed in narrow annular gaps, < 3/4" clearance, might require lower fluid loss values. For squeeze cementing we define the fluid loss according to the job objectives, the formation permeability, and the fluid injection rate. The following table provides a reference to select the required fluid loss value:
To convert the total amount of fluid loss into an API fluid loss value, three parameters are needed: the permeable formation area, the mudcake thickness and its permeability. Static: A maximum acceptable value of the thickness of the cake builtup during the waiting on cement .
A chemical additive used to control the loss of fluid to the formation through filtration. In cementing operations, loss of the aqueous phase can severely affect the performance of the slurry and set cement. In almost any operation, loss of fluid to the reservoir formation carries a .
Loss of fluid from a slurry design, can have serious effects on many key slurry parameters and cement placement. When a fluid loss additive is included in a cement slurry design, it will help maintain desired characteristics and properties such as rheology, thickening time, density and compressive strength.
Well cementing is the process of introducing cement to the annular space between the wellbore and casing or to the annular space between two successive casing strings. ... Cement is introduced into the well by means of a cementing head. ... Uses latex additives to achieve fluid loss.
Cementing Additives are chemicals and materials which is added to acement slurry to modify the characteristics of the slurry or set cement. Cement additives may be broadly categorized as accelerators, retarders, fluid loss additives, dispersants, extenders, weighting agents, lost circulation additives and special additives designed for specific operating conditions.
A fluid loss additive for addition to a cement slurry used in cementing a casing string in a wellbore. The additive reduces loss of water from the slurry into the formation, resulting in a better cement job. The additive is comprised of partially hydrolyzed polyvinyl acetate polymer, calcium sulfate, a crosslinker for the polymer, and optionally a deer.
A waterbased fluid loss additive containing an amphiphilic dispersant has been disclosed [52]. The fluid loss additive is a waterswellable AMPS random copolymer, and the dispersant is a hydrotrope of sodium cumene sulfonate. The ability of a hydrotrope to increase the water solubility of some compounds is known as hydrotropy.
Feb 06, 2001· BACKGROUND OF THE INVENTION. 1. Field of the Invention . The present invention relates to subterranean well cementing operations, and more particularly, to dispersant and fluid loss control additives for well cements, well cement compositions containing the additives and methods of using the compositions.
Fluid Loss Control Agent FLA6 25KG Earth Pro FLA6 is a special blend of products designed to be an effective and economical oil well cement fluid loss additive. Specialty Additives Red Dye 2KG Earth Pro Red Dye is a water dispersible pigment, which can be used as an indicator for
luid loss from cement slurries used in oil well cemening. It is ideal for lightweight cement slurries with long thickening imes. Advantages: Medium temperature (60°–250°F) luid loss addiive. Reduces prema ... CEMENT FLUID LOSS ADDITIVE Appearance at 25ºF White or OfWhite Powder
Comparative tables of fluid loss additives can be found in the internet . Fluid loss additives are also called filtratereducing agents. Fluid losses may occur when the fluid comes in contact with a porous formation. This is relevant for drilling and completion fluids, fracturing fluids, and cement slurries.
Fluid loss control agent. ... Add high temperature fluid loss additive SMP, SPNH, etc. 3) Add asphalt [...] 14 06, 2018 Working principle of CMC filtrate loss reducer ... HIGH TEMPERATURE Oil Well Cement Dispersant; Cementing HTHP Fluid Loss ControlDOOL31; CUSTOMER SUPPORT.
loss controlling additive for oil well cement (Plank et al. 2009). They reported that PVA had very good performance as a fluid loss additive with class G oil well cement from ratio of %2% by weight of cement (bwoc) and it controls the fluid loss by forming a .
When mixed with Class H cement powder, water, a dispersant and deer, this nonionic, low viscosity producing additive will prevent fluid from being lost to the formation in intermediate cementing operations. At bottomhole circulating temperatures of up to 190°F, it is the most commonly used fluid loss control additive in the world.
Jul 25, 2017· Concrete additives are added to the mixture of water cement and aggregate in small quantities to increase the durability of the concrete, to fix concrete behavior and to control setting or hardening. They can either be liquid or powdered additives.
This translates into higher integrity cement, less failure potential and longer term durability During mixing of the cement slurry, many additives that are essential for cement integrity, such as fluid loss additives, and antisettling agents, can result in the generation of and air entrapment.
A novel cement fluid loss additive P1402, which synthesized using the monomers of 2acrylamido2methylpropane sulphonic acid (AMPS), acrylic acid (AA), N,N dimethyl acrylamide (DMAM) and NVinyl2pyrrolidone (NVP) by the method of aqueous solution polymerization.
Fluid Loss Additive for Sea Water Cement Slurries. Fluid Loss Additive for Sea Water Cement Slurries is acclaimed for its pure and effective composition. We offer this chemical in different grades and specifications to meet the diverse requirements of clients.
