    Amélioration des propriétés rhéologiques des fluides de forage à base de biopolymères application aux puits horizontaux
    (2007) Fourar, Karim
    En général, l’étude du comportement rhéologique, de filtration et d’inhibition des fluides de forage sont d’une importance capitale dans le but d’amener l’opération de forage du puit a terme sans aucun problème. Ces caractéristiques vont permettre de maîtriser les propriétés des fluides de forage à base de polymères biodégradables. Le choix a été porté sur ce type de fluide pour des raisons environnementales en vue de leur généralisation sur nos sites de forage

    Shale problems and water-based drilling fluid optimisation in the Hassi Messaoud Algerian oil field
    (2010) Khodja, Mohamed; Canselier, Jean Paul; Bergaya, Faiza; Fourar, Karim; Benmounah, M. Abdelbaki
    Drilling fluid formulation and properties play a fundamental role in drilling operations. Clay minerals behave initially as a beneficial rheological adjuvant in drilling muds. Nevertheless, the contamination of oil reservoirs by clay minerals present in the drilled geological formation (shales) may generate major problems during drilling as plug formation. In this context, our study deals with the optimisation of drilling conditions in the Hassi Messaoud Algerian field. The mineralogical heterogeneity of this field is first discussed. The rheological and filtration characteristics of water-based muds with different polymer and electrolyte concentrations are investigated. The physical and chemical changes of both drilled formation and drilling fluid during the drilling process are studied. Therefore, depending on the clay present in the geological formation, an optimised drilling fluid system using a new filtration procedure is proposed. A good correlation is found between filtration/rheological properties and inhibition
