- The paper describes a novel approach at predicting the restart pressure of waxy crude oils gelled pipelines using constant stress rheological measurements of their yielding and restart pressure data on our laboratory pipelines. Also, gels formation structure was examined microscopically to establish yielding mechanisms. The significance of this work is (i) sharpened guidance for the multimillions problem of restarting gelled oil pipelines (ii) first scientific evidence that waxy oil gels exhibit true yield stress and yielding, hitherto questioned. This work forms part of a continuing programme on the rheology of waxy crude oils sponsored by the Libyan Petroleum Institute.
