The novel percussion method was deployed to test the acquisition technology under real field conditions and provide a basis for comparing the method with conventional coring and core analysis methods. Percussion core samples were acquired...

..., even for wireline operations. Formation pressures can exceed 30,000 psi, and differential pressures over 5,000 psi also exceed the capabilities of traditional rotary coring tools. New technology has been introduced to enhance the recovery of rotary sidewall cores to improve operations and capabilities...

... recovery process designed to enhance sweep efficiency during gas flooding. In this study, we propose a new method to improve oil recovery via synergistically smart seawater with CO 2 . This new method takes advantage of the relative strengths of both processes. We hypothesized that SW depleted in NaCl...

Any missing weight weight loss in the sample that is not commensurate with the oil and water weight recoveries is also accounted for. Water saturation of the fluid-sum porosity is first calculated by assuming...

... of the service. Demonstrating this improved recovery increases the value derived from rotary cores in terms of potential data applications and enhances the viability of reducing conventional coring costs. The planning process uses a wide range of initial inputs that are further refined as additional information...

... be measured volumetrically. Additionally, this fluid recovery can also be measured in weight. A key point is that the fluid summation for processing raw data into porosity can be completed using either weight or volume. Some vendors use weight as a standard process, whereas others use volume. As will be shown...
