Pyrolysis Experiment to Evaluate H2S Generation Potential To semiquantitatively evaluate source rock potential to generate H2S under thermal stress, two separate pyrolysis experiments in open and closed systems were conducted on immature Bakken source rocks. The experimental setups were based...

SEM imaging of fractures created by ScCO 2 injection revealed wider fracture aperture (∼ 4 times) and intense cracking with several lose grains over fractures created by water injection. Based on the experimental results, we have observed...

The availability of direct experimental and field information regarding the pilot becomes an incentive of the current work, which proposes a comprehensive workflow...

... was of particular note from an experimental standpoint. As noted in the methods section, for this sample a brine made from KCl and the Uinta source rock material was used in the experiment. After the brine was created at 65 °C, however, the temperature was allowed to return to ambient room temperature, which...

Previous experimental studies and published field trials have shown that injected surfactants can be an effective means of improving recovery. Most experiments, however, have been conducted at ambient rather...

However, a significant challenge encountered during the process of injecting Carbon Dioxide (CO 2 ) or Nitrogen (N 2 ) to displace oil is the occurrence of asphaltene precipitation and deposition, which can impede production. This work is an experimental study to examine...

To achieve this objective, four experiments were conducted for each cell, and the recovery factors obtained from these experiments were analyzed. The results of this analysis are presented in Figure 2, which shows the recovery factors for all eight experiments...
