PREDICTION OF BARIUM SULFATE PRECIPITATION IN DYNAMIC TUBE BLOCKING TESTS AND ITS INHIBITION FOR WATERFLOODING APPLICATION USING RESPONSE SURFACE METHODOLOGY

Prediction of barium sulfate precipitation in dynamic tube blocking tests and its inhibition for waterflooding application using response surface methodology

Abstract Scale precipitation is one of the major problems in the petroleum industry during waterflooding.The possibility of salt formation and precipitation should be monitored and analyzed under dynamic conditions to improve production performance.Scale precipitation and its dependence on production parameters should be investigated before using s

Role of Ca2+ and L-Phe in regulating functional cooperativity of disease-associated "toggle" calcium-sensing receptor mutations.

The Ca(2+)-sensing receptor (CaSR) regulates Ca(2+) homeostasis in the body by monitoring extracellular levels of Ca(2+) ([Ca(2+)]o) and amino Tub Boot Seal acids.Mutations at the hinge region of the N-terminal Venus flytrap domain (VFTD) produce either receptor inactivation (L173P, P221Q) or activation (L173F, P221L) related to hypercalcemic or hy
