Operasi pengeboran High-Pressure, High-Temperature (HPHT) dengan narrow mud window menuntut sistem fluida inovatif untuk mengatasi kegagalan lumpur berbasis barite konvensional. Tinjauan komprehensif ini menganalisis 15 referensi teknis yang mengevaluasi penggunaan fluida berbasis cesium formate. Fluida ini memberikan solusi unik yaitu kemampuan mencapai densitas ekstrem (hingga SG > 2.0 ) sambil tetap solids-free, sehingga secara drastis mengurangi Equivalent Circulating Density (ECD) dan risiko kerusakan formasi. Tinjauan ini mengkaji aplikasi multifaset, tidak hanya sebagai lumpur pengeboran tetapi juga sebagai fluida komplesi dan fluida pembawa gravel pack (OHGP) berdensitas rekor (SG 2.06) di lapangan Martin Linge. Data lapangan dari Kvitebjørn dan Valemon secara konsisten menunjukkan kinerja sumur yang superior, clean-up alami tanpa stimulasi, dan produktivitas jangka panjang yang melebihi ekspektasi. Makalah ini juga membahas diskrepansi antara data laboratorium dan kinerja lapangan yang sukses , menyoroti stabilitas termal dan tantangan operasional fluida formate.
