Case Studies

Case Study #1 | Frac On-site Testing

A Permian Based Operator started a produced water recycling program for their hydraulic fracturing operations. GeoKimika personnel performed a process audit and on-site testing during hydraulic fracturing operations to identify gaps. GeoKimika’s on-site consultants improved treatment program, resulting in a 30% cost-savings on chemicals to the Operator.

Case Study #2 | Drillout Testing Services

A Permian based operator detected iron sulfide and high bacteria counts when bringing their newly completed wells on production. GeoKimika provided on-site testing support during a drillout operation and tasked with improving the process for maintaining water quality. A water management and biocide treatment program were implemented with 55 wells successfully treated.

Case Study #3 | On-site Friction Testing

A Permian based operator had performed pre-job testing in the lab to determine field trial candidates with best compatibility in 100% produced water. However, during fracturing operations, high friction pressures limited the ability to use more than 25% produced water. GeoKimika evaluated the products on-site and determined why performance did not meet previous lab testing results. Based on findings, GeoKimika was asked to recommend ideal candidate for a field trial. The recommended product showed reduced chemical usage by 50% and allowed them to use 100% produced water.

Case Study #4 | Water Monitoring to Optimize Friction Reducer Performance

A major operator in the Permian Basin had on-going fracturing operations with a new source of recycled water. They were faced with higher friction pressures, limiting their ability to achieve rate, and target stages per day. It was believed that water treatment processes were affecting performance, however the water company’s result showed all KPI’s being met. GeoKimika implemented a water and testing protocol and continues to support all recycled water fracs for this operator, ensuring the right friction reducer is used for the current water source.
