... development. Additional challenges included low porosity-low mobility reservoirs where fluid collection at low contamination in reservoirs with elevated temperatures of approximately 410°F (210°C) is considered a necessity. This operator pioneers the use of novel hostile wireline formation testers globally...

... being recorded as ‘Dry’, ‘Tight’ and ‘Supercharged’. However, by exploiting the extreme limits of new generation formation testers such as low volume and relatively lower rates, we were able to overcome these difficulties and record valuable formation pressures. The electromechanically controlled...

By calibrating the high resolution flow model with dynamic test data from a formation tester Interval Pressure Transient Test (IPTT), the model can be used to predict the well performance. We investigate several key characteristics of thinly laminated reservoirs...

... traditional wireline formation testers becomes very complicated in view of these factors. In fact, 20 samples were acquired from this region and the laboratory deemed all of them non-representative. The OBM contamination levels in all these samples were more than 15%. It was thought that a focused sampling...
