The Influences of NP100 Surfactant and Pine-Oil Concentrations on Filtrate Volume and Filter-Cake Thickness of Microemulsion-Based Drilling Fluids (O/W)
Autor: Agostinho C. B. Junior, Raphael R. Silva, Giovanna L. R. Leal, Tarsila M. Tertuliano, Rafael P. Alves, Alfredo I. C. Garnica, Fabiola D. S. Curbelo
Publikováno v: Energies, Vol 14, Iss 16, p 4965 (2021)
In this work, nonionic surfactant NP100 and pine oil influences on the filtrate volume (FV) and the filter-cake thickness (thkns) of microemulsified drilling fluids were studied. A ternary phase diagram was obtained to define the microemulsion region

Publikováno v: Energies, Vol 13, Iss 12, p 3135 (2020)
Over time, oil production in a reservoir tends to decrease, which makes it difficult to flow through the reservoir to the well, making its production increasingly difficult and costly. Due to their physical properties, such as reducing the water/oil

In the cementing operation, it is necessary that the entire circumference of the annular is filled by the cement slurry and that it develops adhesion to the casing and formation. For this, an efficient removal of the drilling fluid is necessary, whic

Microemulsion is a thermodynamically stable dispersion consisting of an aqueous and an organic phases, both stabilized by surfactant molecules and when in need, co-active surfactant. The nature and structure of these components are essential in the f
