TEKKON PETROCHEMICAL SERVICES CO. LTD.
CLIENT1, X1 and X2 WELLS DEMULSIFIER TESTS REPORT
TEKKON Petrochemical Services Co. Ltd. supplied OilFit1 oil based demulsifiers showed high quality performance for both X1 and X2 crudes during heat and centrifuge applied bottle tests. The product also showed high efficiency during heat applied 5 hour settling tests.
Upon request and support by CLIENT1, TEKKON Petrochemical Services Co. Ltd. technical team conducted a series of demulsifier bottle and settling tests in order to treat the emulsion observed in X1 well, and X2 well’s free water separation.
Methodology and Testing
Testing Team: TEKKON Petrochemical Services Co. Ltd. technical team
Tested Crudes: CLIENT1 X1 and X2 crudes
Testing Method: Centrifuge applied bottle tests, settling tests
Testing Equipment: Koehler Percentage Graduated Centrifuge Tubes, Centrifuge with built-in heater.
Testing Temperature: 158F (70⁰C)
Number of Demulsifiers Tested: 16
A 2-step testing methodology is applied. The first test consisted of blank and demulsifier dosed, heat applied centrifuge bottle tests, and the second test consisted of heat applied 5-hour settling test.
X1 Treated With OilFit1
X2 Treated With OilFit2
CONCLUSIONS and PROPOSITIONS
Following the data obtained from the tests, the following conclusions are reached:
– OilFit1 product has proven to be able to break down the entirety of the emulsion present in X1 crude, and separate the maximum amount of water. The crude/water separation is clear, and non rigid. No interfaced emulsion/salt formation is present.
– OilFit1 product has proven to be able to break down the artificial emulsion created with 10% synthetic produced water for X2 crude. The crude/water separation was also clear, non rigid, and non interfaced by leftover emulsion or salt formation.
– Within 1 hour, the X1 samples showed above 20% free water (up to 26% at the end of 5 hours). This also shows the efficiency of OilFit1 product , since the product not only managed to eliminate the water from the emulsion, but also collected and separated the small bits of water trapped inside the crude phase.
