Geothermal Power Producer Significantly Increases Production and Revenue

GoalRestore production well to original capacity.

<p class="p1"><strong>Customer Challenge</strong></p> <p class="p2">An Indonesian geothermal power producer was facing issues caused&nbsp;by calcite scaling in a production well. The capacity of the production&nbsp;well decreased from 1,000 tph to 388 tph in one year, a 61% decrease&nbsp;in production. The power plant initially attempted to restore the dying&nbsp;well using a coil tubing unit but this did not improve the situation. To&nbsp;restore the well, the plant reached out to Solenis for help.</p> <p class="p1"><strong>Recommended Solution</strong></p> <p class="p2">After performing a thorough audit of the production well, the Solenis&nbsp;team recommended its novel GeoSol well cleaning program paired&nbsp;with tailored solutions from the GeoSol line of products. Specific&nbsp;products were prescribed to ensure the removal of the calcite&nbsp;blockages from the well while protecting the casing.</p> <p class="p1"><strong>Results Achieved</strong></p> <p class="p2">After completion of the well cleaning program, the flow rate&nbsp;significantly improved to 902 tph at 38 bar, equating to approximately&nbsp;39.6 MW of production. Upon inspection, it was discovered that the&nbsp;well could produce more than its original estimated capacity (see chart&nbsp;below). The Solenis method not only cleaned the well but also&nbsp;enhanced the permeability around the wellbore, contributing to the&nbsp;increased output. Notably, the cleaning program enabled the power&nbsp;producer to increase its revenue by $2.4 million annually and avoid&nbsp;having to drill a new well, which would cost approximately $9 million.</p> <p class="p2"><img style="max-width: 100%; width: auto; height: auto;" src="/link/2b5396241c4f4168a595cca2f2177149.aspx" alt="" width="1254" height="352" /></p> <p><strong>After the novel method&rsquo;s cleaning was completed, the well showed significant increases in flow above the original capacity.</strong></p>
