Exclusive Interview with Mr. David Eshemitan (Sinopec Int'l Petroleum E & P Co. Nigeria Ltd)
The Challenge is to carry out studies that tell you best technology to employ. This takes some times to do and must be carried out by an expert who knows what he or she is doing. Some studies would have to detail short term and long term process technology. You should consider and settle for long term measures. Short term measures are basically for emergency nature such as the need to sustain production versus temporal measure to manage produced water. However, this points to poor planning or forecast in the first instance. Measures should have been in place before first production started. Beside I bet, which authority would allow you to operate when conditions for protection of the environment and life has not been met? Studies would consider proximity of nearby facilities natural and manmade that supports the process technology. Distance to sea or reservoir for re-injection. If process technology entails discharge of treated water into sea, then the technology must meet specification as in parts per million (ppm) of
pollution allowed or sets by national authority for the operating standard that discharges to sea water. The ideal situation is not to allow any pollution at all and that is the greatest challenge for the oil and gas industries.
For discharge to sea involves the right process technology, pipelines and land acquisition as the case may be. For re-injection process technology, you must consider factors such as whether for well recovery or to fill voids. However, it is always most times for well recovery supports. This requires further studies to ensure best positions for re-injection so as not to destroy the well formations. Whichever, technology chosen must also consider factor of the amount of water to be managed, capital investment recovery and robust technology that is best available to manage.
Talking about robustness, there are trends everyone in the oil and gas industries are looking for now: Availability of modules, cheap technology, maintainability, less manning, fire resistance protections, low operating cost, spare availability, quick and easy set-up and dismantling time and mobility. It is not limited to these. Many are also looking at sizes especially small size with moderate automations yet can handle large volume of produced water. I mean manufacturers/designers would consider not making anything complex like rocket science where companies will exhaust resources in manpower training in the operation of the process technology. Many would also consider integrating international standards with local technologies, standards in achieving the overall specific and peculiar goals. In conclusion, there is selection studies for the best option to take, there is engineering studies and construction activities for your chosen process technology.
Not enough? Join us at the world leading Produced Water Management Summit 2015 from 24-27
February 2015 in Singapore to hear more discussions and sharing on Produced Water Management, where global oil and gas operators gather at Singapore to discuss and share produced water management strategies through real-life case studies to overcome key challenges in produced water production control, treatment technology selection and facilities design, produced water re-injection and disposal management.
P.S. Limited Opportunities to Attend/Exhibit/Sponsor this summit is available. Email us at enquiry@equip- global.com for more information
