Usage of additives of barite formation fluid invasion jobs is a common Thing. Barite formation fluid invasion using many constrained problems. Such as pore blockage by particles barite’s rock and clay can’t resolve the problem. To replace the position of barite as an additive in the formation fluid invasion is used bri ne, but the problems faced lies in the level of fluid salinity brine, brine content consist of several types of cation and anions, the most risk ions are the strong polar anion. Strong polar anion (high salinity) result collapse formation by clay moisture adsorption (Osmosis). While the low salinity result inmoisture adsorbtion into the clay /formation or can be called “Swelling”. To overcome the problem of non polar brine is the answer, this solution can be categorized as a inert substance (a substance not reactive with formation). The lack of this reactive answer all the problem in the formation fluid invasion jobs. Inert in non-polar brine is used nitrated (NO3) and phosphate (PO4) , while its companion with sodium and potassium as its cation. The solution used for the reference is CaCl2 and KCl (a solution of polar). To compare this is done base on the standard API 19B section 4 test. The result of this study showed non-polar brine is more recommended in the formation than the others, and indirectly make BOPD increase. Besides that using non-polar brine can minimize corrosion effects and All the products in nature will turn into either/both Nitrogen and Phosphorous Fertilizer. * University of Trisakti ** PT.
