The effect of testing conditions on the performance of lost circulation materials: understandable sealing mechanism
Lost circulation materials (LCMs) are added to drilling fluids to mitigate lost circulation (LOC) problems. Designing the fluid requires a good understanding of sealing mechanisms and all the parameters affecting the sealing performance.
Products OSS offers a complete range of premium quality specialised drilling, completion and workover fluid additives. If you are experiencing a problem or looking to enhance performance, our experienced technical team can supply, recommend and
Experimental Investigation on Plugging Behavior of Granular Lost Circulation Materials in Fractured Thief Zone
Lost circulation of drilling fluid occurs frequently when drilling in fractured formations. Granular lost circulation material (LCM) is still widely used as a cure to combat the circulation loss

- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- When was polyacrylamide first used in drilling mud?
- Polyacrylamides were first introduced as an additive to drilling muds in the 1960s. The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers.
