Application of ceramic membranes in the treatment of oilfield-produced

Microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), membrane distillation and their combined processes are often used to treat the produced water. Most previous reports have focused on the influence of oil on the membrane filtration process.

Effective Modified Xanthan Gum Fluid Loss Agent for High-Temperature

Xanthan gum (XG) was widely used as an oilfield chemical treatment agent because of its environmental protection and diverse functions. With the increased drilling depth and formation complexity, the shortcomings such as poor solubility and low resistance to temperature were gradually exposed. In this study, a modified XG derivative XG-g-AAA was synthesized by grafting XG with acrylic acid (AA

The backwash water samples were then used for the laboratory tests without a long storage time, on the day of sampling. The refrigerated samples were treated by the different flocculent additives, applying the so-called ¡®jar test¡¯ procedure according to the water treatment standards [2].

study of a polyamine inhibitor used for shale water-based drilling

Study of a Polyamine Inhibitor Used for Shale Water-Based Drilling

Here, we report a water-soluble shale inhibitor for inhibiting shale hydrate formation. The copolymer denoted as thermogravimetric analysis (TGA) was synthesized via triethanolamine, two maleic anhydrides, and glacial acetic acid. The infrared (IR) and gas chromatography (GC) results indicated that TGA is a low molecular weight polymer inhibitor (IR) and is the most commonly used method to
