POWELTEC IS AN INDEPENDENT SERVICE COMPANY DEDICATED TO THE IMPROVEMENT OF OIL AND/OR GAS FIELD PRODUCTION BY THE USE OF POLYMER TECHNOLOGY

Thanks to its deep knowledge in polymer technology POWELTEC is one of the leaders in the following domains

MAIN DOMAINS OF ACTIVITY

WATER SHUT-OFF / CONFORMANCE CONTROL

Water Control is a major issue for oilfield operators. POWELTEC WSO/ CC processes have been successfully applied in more than 100 field cases worldwide, including oil and gas wells, multi-layer waterflooded wells, vertical and horizontal wells, fractured formation, sandstone and carbonate reservoirs, etc.
 

SAND CONTROL

Sand problems strongly affect oil and gas production, increasing operating and maintenance costs and damaging well and surface equipment. POWELTEC has obtained remarkable results in the treatment of gas wells and offshore oil wells by simple bullhead treatment, Sand mitigation can last several  years. Re-treatments have also been performed with same efficiency.
 

EOR / POLYMER FLOODING

POWELTEC staff has been involved in all the major breakthroughs achieved in polymer EOR for 45 years. The design of the first polymer flood pilot in Daqing (China) (the largest polymer flood project worldwide), the conception of the first heavy oil horizontal well polymer flood in Pelican Lake (Canada), and the first deep offshore polymer flood in Dalia (Angola) are evidences of this leadership.
 

ALAIN ZAITOUN, CEO

CEO Alain Zaitoun received his PhD in Chemical Engineering in 1979.  After 30 years spent in R&D, he established in 2007 his own company Poweltec. Alain has authored a number of technical publications and patents. He was member of the Steering Committee of the SPE Oilfield Chemistry Symposium and SPE Distinguished Lecturer (2009-2010) on Polymer IOR applications.
Alain Zaitoun​’s team have a comprehensive background and knowledge of O&G operators.

ENVIRONMENTALLY FRIENDLY

Different families of products with low environmental impact have been designed for for Water Shut-Off, Conformance Control and Sand Mitigation.
The products are environmentally friendly. They can be used at high temperature and high salinity.
Many of them are CEFAS registered for applications under severe offshore regulations.

R&D PROGRAMS

POWELTEC keeps building its expertise through extensive R&D activity in partnership with universities, research centers, chemical manufacturers and oil field operators. Recent POWELTEC R&D activity has been devoted to EOR polymers for high temperature reservoirs (up to 120°C) and the development of an innovating generation of WSO/Conformance and Sand Control products that can be used in harsh conditions (high temperature/high salinity) and in complex reservoirs (fractured carbonates).

POWELTEC breaking news - WSO in fracturated carbonate oil Wells

The 6th Water Shutoff treatment campaign with Daleel, involving two horizontal and one vertical wells, has been achieved in September 2024.  In total, 38 WSO treatments have been performed since 2019, with a success rate of 75%.  Some wells treated several years ago continue to produce additional oil today, thus showing the remarkable longetivity of the Poweltec WSO technology combining Microgel and Gel. All treatments have been performed by simple rigless bullhead chemical injections and are thus very cost effective on top to be low-risk technology.  Additional oil produced so far is estimated as 500,000bbl and continue to grow for wells initially almost watered out.

Several papers have been published around this project (SPE 203394, SPE 217009, SPE 218438).  Next one should be presented at the OPES 2025 (Muscat), in May 2025.
