Glycerin-based fluids are proposed as a promising alternative to inhibited in the drilling of highly-reactive formations. However, even with use these fluids, it is still possible observe occurrence problems related balling drill bits and pipes, such agglomeration accretion cuttings. This study aims analyze how interaction between expandable minerals from reactive formations glycerin-based affects stability oil wells, focusing on extent phenomenon. For this purpose, bentonite pellets were...
A study was made of the influence ionic strength (S) on apparent (AV) and plastic (PV) viscosities water loss (WL) sodium bentonite suspension with polymers. Na-bentonite dispersed in (4.86% w/w) different strengths (S = 0.0, 0.015, 0.030 0.045 M) followed by addition polymer. Three polymer samples were studied, i.e., low viscosity carboxymethyl cellulose (CMC BV), polyanionic (PAC), partially hydrolyzed polyacrylamide (HPAM). The results indicated that presence salts increased salinity...
This study aims to evaluate how the operational procedure adopted for pellets placement and exposure subsurface conditions influences mechanical integrity of bentonite plugs used as barrier elements in abandonment petroleum wells. To this end, two methodologies were obtain plugs: from first methodology, immersed diesel or olefin, which are proposed displacement fluids offshore operations, then, hydrated deionized water; second representative onshore directly water. After that, tested by...
Plug and abandonment (P&A) operations demand valuable time resources with operational procedures materials to establish the well barrier element. This study proposes use of a water-based fluid as liquid element for temporary abandonment, based on esti-mates its lifespan survival probability downhole conditions acquired through acceler-ated life tests. For that, formulation was tested exposed 95, 110, 140 150°C, intervals ranging from 1 10 days. After temperature exposure,...
The use of residential construction wastes and residues from the red ceramic industry in alternative mortars was studied. Specifically, influence surface area these residues, determined by Blaine method, mechanical behavior those were investigated. materials are two hydrated limes four pozzolanas (a residue bricks tiles, wastes, one artificial pozzolana). These characterized using studies chemical composition, thermal differential analysis, x-ray diffraction. ground to obtain a distribution...
One of the operational challenges regarding use bentonite pellets as sealing materials in abandonment offshore fields consists their placement inside well. This study aimed to analyze interaction fluid media, consisting saline solutions (NaCl, CaCl2 and KCl) organic compounds (diesel, glycerin olefin), with pellets, for applications displacement fluids oil well operations. The physical integrity contact was verified through visual inspections dispersibility tests. Linear swelling tests were...
Este trabalho teve como objetivo estudar a influência do tipo de ferramenta, da velocidade e tempo agitação nas propriedades reológicas dispersões quatro amostras argilas bentoníticas sódicas industrializadas no Estado Paraíba, Brasil. Foi realizado um planejamento fatorial 2³ para avaliar os fatores entrada (tipo agitação) sobre as viscosidades aparente plástica o volume filtrado. As foram preparadas na concentração 4,86% em massa argila (24,3 g 500 mL água deionizada) utilizando...
Este trabalho tem por objetivo avaliar o efeito da utilização de compostos poliméricos na aditivação bentonitas Boa Vista, PB, consideradas qualidade inferior, para em fluidos perfuração à base água, visando a melhoria das suas propriedades reológicas e filtração. Foram estudadas uma amostra argila bentonítica três amostras aditivos poliméricos, sendo poliacrilamida parcialmente hidrolisada duas carboximetilcelulose diferentes graus viscosidade. O dimensionamento composições do composto...
The influence of carboxymethylcellulose, CMC (filtrate reducer) and xanthan gum (viscosifier) in plastic apparent viscosity at yield strength the volume filtrate composition drilling fluids based on water was investigated statistical design. Five formulations consist a range concentrations used commercially were utilized design experiment. prepared accordance with company standards Petrobras. Regression models calculated correlated properties compositions. relevance validation confirmed by...

Resumo O problema da estabilidade do poço em formações expansivas frustrou os engenheiros de campos petróleo desde o início exploração e gás natural. A folhelhos ricos argila é profundamente afetada por suas interações físicas químicas complexas com fluidos perfuração. Assim, estas rochas alto teor mostraram alterações significativas, tais como inchaço ou expansão, quando colocadas contato aquosos para a adsorção moléculas polares água íons hidratados dissolvidos no meio. Essas mudanças...
RESUMO Amidos e seus derivados são utilizados em praticamente todos os setores industriais. Na indústria petrolífera podem ser empregados como aditivos controladores de filtrado, quais controlam eficazmente a perda fluido para formação rochosa adjacente. O presente trabalho teve objetivo avaliar o uso amidos, mandioca milho, na mineração, redutor filtrado fluidos perfuração poliméricos poços petróleo gás. estudo foi realizado três etapas: primeira etapa, cinco diferentes tipos amidos...
Este trabalho avalia a influência dos cátions Ca2+ e Mg2+, através da eletrodiálise, na reologia de dispersões argilas bentoníticas Boa Vista, PB. As argila foram preparadas com 4,86% em massa, realizado o processo eletrodiálise uma membrana polimérica catiônica, um reator bancada, sendo utilizadas tensões 7, 10 13 V tempos ensaios 40, 80 120 min, segundo planejamento fatorial do tipo 2² + 3 experimentos no ponto central.
