Paper: (2015027)REVIEW OF ONSHORE TEXAS PARAFFIN PROBLEMS AND MITIGATION TECHNIQUES

: Paraffin is one of the major flow assurance problem in west and south Texas.  The mitigation techniques for the case of onshore paraffin deposition is different from the offshore case.  Chemical treatment is used instead of a pigging method for the onshore case.  The current reliable methods for the onshore paraffin treatment are (1) downhole chemical injection, (2) solid paraffin inhibitor pumped during hydraulic fracturing, (3) hot water or oil circulation.  The magnetic conditioning is also being 

used in some field, despite the lack in the understanding of this method.  

This paper reviews the current understanding in paraffin deposition problem (single-phase, oil-water, gas-oil), mitigation technique and its current development.
