    Arabic Abstract

    في هذه الرسالة تم تقييم عدة مخاليط من الاحماض العضوية وحمض الفلور لتحفيز الصخور الرملية. عادة, يتم استخدام الاحماض العضوية كبديل لحمض الكلور لتجنب السلبيات مثل التفاعل السريع, التآكل و عدم التوافق مع بعض انواع الصخور. تركز هذه الرسالة على التفاعلات بين هذه الاحماض وانواع مختلفة من الصخور والترسبات التي تتكون اثناء هذه التفاعلات والعوامل التي تؤثر عليها. كما يوفر هذا العمل تحقيق منهجي للتفاعلات الكيميائية بين الاحماض والصخور تحت عدة متغيرات. أخيرا, تعرض نتائج تجارب "الكورفلود". بالإضافة إلى ذلك, فإن هذه الدراسة تلقي الضوء على النتائج والتوصيات الرئيسية.

    English Abstract

    Different organic-HF acid mixtures have been used to stimulate sandstone formations. Typically, they are used as alternative to regular mud acid in order to overcome its potential limitations such as rapid spending, high corrosion rate and incompatibility with sensitive clays. This study focuses on identifying the type of precipitations that occur during reactions of organic-HF acids and on determining the factors that affect these precipitations. This work also provides a systematic investigation of the chemical interactions of various sandstone minerals with three different organic-HF acids over a wide range of parameters. Finally, the results of coreflood experiments using organic-HF acid mixtures are presented. In addition, this study highlights the main findings and recommendations as well.
