This session recognises that effective scale inhibition remains a challenge for many operators in terms of high cost chemical deployment systems, selection of appropriate chemicals and the ability to monitor reliably and in real time the efficiency of inhibition. The knowledge base is growing rapidly thanks to on-going research and some exciting new developments, which authors of the papers presented in this session are kindly going to share with us.
Notable work discussed here includes recent advances in mineral scale control with a combination of polymeric dispersants and phosphonate inhibitors and a novel evaluation method using a test rig able to reproduce downhole flow at realistic rates.
A well-documented challenge associated with calcite inhibition measurements is addressed in a new way with a laboratory test method that can be applied to a broad range of production conditions.
The results of a study of electromagnetic devices on the scaling process provide a welcome assessment of the potential of this non-chemical scale inhibition method, which has for some time captivated the attention of researchers. And to highlight the latest in novel developments, an experimental example of using graphite as a sacrificial scaling material for calcite scale management, using electrochemically enhanced deposition, is presented.
