Cementing oil-wells has no hidden secrets for us. In fact, we even design special ultra-low density slurries that are at high and extreme temperatures or geothermal wells. Such challenges are overcome by applying ISI professionals’ engineering knowledge and proccesses in our labs. Thus, the most efficient slurries are designed by using local products manufactured by Isi Oilfield Chemicals.
