Statistical Analysis Of Polymer-Based Gel For Water Shut-Off Treatment In Oilfield Application

Air yang dihasilkan di telaga minyak akan mengurangkan pengeluaran minyak dan gas dan ia merupakan sisa terbesar di dalam industri minyak dan gas. Untuk mengurangkan pengeluaran air yang tidak diingini, rawatan kimia menggunakan polimer adalah fokus dalam kajian ini. Biopolimer gam xanthan dan bahan...
