C&P Presents: “The Myth and Facts about Diversion”
Fluids introduced into a wellbore for stimulation applications typically take the path of least resistance and therefore frequently go into areas where there are open flow paths. In many cases, these are neither areas you want to stimulate to enhance production by using a refracturing operation in unconventional reservoirs, nor areas from which formation damage needs to be removed by using an acidizing operation in carbonate reservoirs. Recently developed solid particulate degradable diverters promote efficient plugging, which helps to create nearly impermeable seals and aids fluid diversion. These solid particulate materials are capable of degrading over time from a solid polymer state to a clear, nondamaging, liquid monomer solution, eliminating the need for mechanical removal after intervention. Although several field applications exist for this technology, less attention has been paid to the underlying physics and controlling parameters. This presentation describes how different advanced modeling (analytical and numerical), experimental, and field data mining approaches can be used to design and optimize different stages of fluid diversion. Application of lessons learned and engineered design key practices are shown by means of case studies.
