Tackling an underperforming well
The downturn we are facing is here for the foreseeable future. Oversupply is a current reality and, for at least the next couple of quarters, the various stakeholders in oil and gas must operate with ingenuity to maximize asset value whilst minimizing cost. No longer can oilfield companies continue to operate as they did at $100 oil and expect an outcome that is sustainable at $30 oil. To meet the expectations of operators and other stakeholders changes must be made, new areas of innovation and cost efficiency must be explored.
One such area in which efficiencies can be made is wellbore cleanup. Operators around the world are becoming increasingly aware of the importance of a clean wellbore throughout the productive life of a well. In addition to achieving effective cleanup of new wells, the uniform removal of production related damage such as carbonate scales may also be required to maximize well performance. Chemical cleanup is a key area where innovative reservoir chemistry can cost-effectively make a substantial impact on asset performance.
Tailored treatments that are proven to work
Since 1994 Cleansorb has pioneered the use of in-situ acidizing in the oil and gas industry. It remains the only specialty oilfield chemicals company entirely focused on in-situ acidizing, particularly as a component of filter cake breaker systems. With knowledge of a drilling fluid’s composition followed by testing of representative fluid samples, Cleansorb is able to select the appropriate breaker chemistry. This ensures a breaker fluid formulation customized to the operator’s needs to maximize drilling damage removal and optimize well performance.
Effective cleanup of filter cake yields real benefits
In a heavy oil reservoir located in Asia, a series of wells were drilled with OBM and completed with standalone screens set across multiple producing zones separated by shales. No mud damage removal treatment was used before well activation and production rates were well below expectations. A suitable ORCA for OBM formulation was identified in Cleansorb lab tests, independently validated in a third party lab and applied in the field on producing wells. Highly effective drilling damage removal was evident with five wells averaging pre-treatment production rates of 300bbl/d increasing to an average of over 1000bbl/d after ORCA for OBM treatment.
Stand out with higher production rates
Cleansorb’s patented reservoir chemistries are designed to uniformly dissolve drilling fluid filter cakes or other acid-soluble damage to deliver increased production rates. This is consistently delivered through tailored formulations. With ORCA and DEEPA treatment costs being a fraction of total well development costs, investing in proven wellbore cleanup fluids pays dividends on the eventual cost of completing wells efficiently, delivering better production rates and extending the life of wells.
Cleansorb’s innovative reservoir chemistry solutions can help operators achieve their goals of improved production at reduced cost to stand out from their peers.
