CTAB grafted PAM gel and its application in drilling fluid

FTIR spectra confirms the formation of PAM complex by grafting of CTAB with PAM. On comparing PAM complex spectra with PAM it is observed that few peaks disappeared like peaks at 3341.4 cm ?1, 3185.16 cm ?1,1657.5 cm ?1 of PAM and formation of new peaks at 1462.31 cm ?1, 960.26 cm ?1 confirms the structural modification.

Shale inhibition by low-molecular-weight cationic polymer in water-based mud - Journal of Petroleum Exploration and Production Technology

34 Citations Explore all metrics Abstract The presence of oligomers possessing amine or ammonium functionality in drilling fluid plays an important role in stabilizing the shale formations during drilling with water-based mud. In this study, we have compared the activity of neutral to charged amine polymers towards shale stabilization.

Applied Sciences | Free Full-Text | Zwitterionic Polymer P (AM-DMC-AMPS) as a Low-Molecular-Weight Encapsulator in Deepwater Drilling Fluid

In deepwater oil and gas drilling, the high-molecular-weight encapsulator aggravates the thickening of the drilling fluid at low temperatures. Therefore, it is hard to manage the downhole pressure, and drilling fluid loss occurs. In this paper, a zwitterionic polymer P(AM-DMC-AMPS) which was the terpolymer of acrylamide, methacrylatoethyl trimethyl ammonium chloride, and 2-acrylamido-2
