OLI ScaleChem ScaleChem predicts mineral scaling potentials of 70+ solids for virtually any oil and gas well and processing facility in the world. The program computes the gas-liquid-oil-solid chemistry of produced fluids, and provides the operator and engineer with vital chemical data about their wells, surface facilities, and water injection and disposal operations. ScaleChem works with brines, gases, and hydrocarbons, collected as samples and input into the program. Calculation types include a generalized scale scenario for well profiles; mixing waters to find safe (non-scaling) ratios; reservoir saturation to simulate downhole conditions; and facilities wth simple mix and separate abilities to simulate collection and disposal. Output includes the (thermodynamic) scale tendencies for all solids in the model, as well as scale amount produced, if any. ScaleChem uses OLI's AQ model for a fixed chemistry:

Industry standard ScaleChem was written orginally by Shell Oil Company using the OLI thermodynamic model. OLI has maintained, extended and support ScaleChem and ScaleChem clients since then. ScaleChem is predictive to 300 C (600F), 1,500 bar, 70 wt% electrolytes (Na+,Ca+2, Cl-, etc.), and 60 wt% methanol or ethylene glycol. In addition, ScaleChem simultaneously computes scale tendency and deposition at key process points. |
