This work has developed and evaluated a microemulsion-based drilling fluid formulation with characteristics to be applied in oil wells. The microemulsion was formulated solution of water/glycerol, pine oil, Tween 80, nonionic biodegradable surfactant. physical chemical properties the obtained this were investigated through rheology filtration analysis, solids content, aging, lubricity, toxicity, thermal degradation. A non-toxic oil-in-water (O/W) high lubricity (0.07638) stability suitable...
In this work, nonionic surfactant NP100 and pine oil influences on the filtrate volume (FV) filter-cake thickness (thkns) of microemulsified drilling fluids were studied. A ternary phase diagram was obtained to define microemulsion region, where a 2k factorial design used with addition four center points axial points. Twelve defined later in formulation investigated fluids. The results showed that increase oil’s concentration increased FV thkns, withthe being most influential component...

Microemulsion is a thermodynamically stable dispersion consisting of an aqueous and organic phases, both stabilized by surfactant molecules when in need, co-active surfactant. The nature structure these components are essential the formulation microemulsified systems. For this, construction phase diagrams can be fundamental tool to characterize ideal experimental conditions for existence operation microemulsions. Thus, present work had as objective obtain comparison between microemulsions...
In the cementing operation, it is necessary that entire circumference of annular filled by cement slurry and develops adhesion to casing formation. For this, an efficient removal drilling fluid necessary, which requires its chemical composition compatible with slurry. The objective this work formulate a in micro emulsified system test compatibility assess effects unwanted contamination can have on properties test, rheological compressive strength contaminated different volumetric proportions...
Drilling fluid additives play an essential role during drilling operations. The acceptable choice with the correct properties interferes deeply operation's success and well's total costs. Shellfish shells are residues from consumption of mollusks. These rich in calcium carbonate, additive widely used fluids as a bridging material. Furthermore, no studies have investigated using these seashell microemulsion-based (MEDFs). This work aimed to use residue powder (SSRP) material fluids. For this...
Um dos fatores mais importantes para que a perfuração de um poço petróleo seja bem sucedida é composição do fluido perfuração. Portanto, essencial esses fluidos sejam formulados modo garantir eficiência e segurança da poço. Este trabalho teve como objetivo analisar influência duas argilas, uma delas organofilizada, na microemulsionados, denominados FP1 FP2. Os resultados obtidos mostraram argila bentonita organofílica desempenhou papel importante diminuição parâmetros reológicos no volume filtrado
