Optimizing the Effect of Gambir Sap Extract as an Organic Inhibitor to Reduce Scale Formation at Pertamina Hulu Energi (OK/RT) Peninjauan District, OKU Regency

The formation of scale can cause a decrease in production at the well due to obstruction of flow in tubing flowlines and other production equipment; besides that, it can also cause damage to production equipment. The contents contained in the scale include calcium sulfate, ferrous sulfate, calcium carbonate, and barium sulfate. Among some of the scale content, the highest content of barium sulfate to reduce the content of barium sulfate scale can use inorganic materials such as HCL and H2SO4 for this study using H2SO4 because the dilution solvent is large enough compared to HCL so that it can be used to reduce scale in addition to inorganic materials can also use organic materials such as in this study using gambier sap extract which has a fairly high tannin acid content which is certainly more environmentally friendly and inexpensive.
