برخی مواد مورد استفاده در ساخت گل که در شرکت کلان حفار عرشیا تولید می شود :
1-نشاسته پری ژلاتینه
نشاسته پری ژلاتینه یک نوع نشاسته اصلاح شده می باشد که می تواند در آب سرد حل شده در حالی که نشاسته خام این قابلیت را ندارد. همچنین این نوع نشاسته قدرت جذب آب و تورم بیشتری نسبت به نشاسته خام دارد و به عنوان کاهش دهنده مصرف آب ، کم کننده میزان مصرف گل حفاری ، مقاومت در برابر حرارت ، ایجاد ویسکوزیته بالا ، خنک کننده مته حفاری و جلوگیری از ریزش دیواره های حفاری استفاده میشود. نشاسته با فرمول شیمیایی C12H22O11 به عنوان افزودنی در سیال حفاری مورد استفاده قرار می گیرد. نشاسته ممکن است از سیب زمینی، ذرت، گندم و یا سایر گیاهان نشاسته ای تهیه شود. از جمله مواد مورد استفاده در جلوگیری از هرزروی سیال حفاری، مواد پلیمری مانند نشاسته سبز و قرمز (Red and Green Starch) می باشد که برای تشکیل فیلتر کیک نازک و صاف و ناتراوا درون چاه کارایی بالایی دارند. نشاسته قرمز که تهیه شده از جوانه گندم است برای بهبود نقطه واروی و نشاسته سبز که تهیه شده از سیب زمینی است می تواند برای افزایش گرانروی نیز مورد استفاده قرار گیرد.
