Descripción
The mechanical approach of utilizing high-pressure water for scale removal has gained wider acceptance by multinational despite facing poor downhole performance challenges (cavitation) that need abrasion compensation (sand). Although sand particles have side effect of jeopardize the integrity of the well completion. The replacement of sand with stealing beads was excellent with good post descaling well completion integrity at the expense of environmental complexity. While the recent single nozzle, solid free aerated jetting descaling technique was characterized with poor scale coverage and high descaling time. This novel experimental scale removal technique utilizes multiple high-pressure spray of up to10MPa and low flow rate of 12 l/m from multiple flat fan nozzles of different arrangement and stand-off distance. Housed in a constructed simulated production tubing chamber with vacuum and compression capacities to remove constructed wax deposit (paraffin) of different shapes signifying different growth stages of paraffin in production tubing.
