... strength (UCS); and core recovery was expected to be a challenge. 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...

... 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...

... ABSTRACT Secondary oil recovery projects in naturally fractured carbonate reservoirs (NFR) often introduce uncertainties and challenges that are not common to conventional waterflood. The recovery mechanism in NFRs relies on ability of fracture network to deliver enough injected fluid...

... Abstract The current available technique to produce shale oil is through primary depletion using horizontal wells with multiple transverse fractures. The oil recovery factor is only a few percent. There is a big prize to be claimed in terms of enhanced oil recovery (EOR). Well productivity...

...-recognized strategy for more efficient hydrocarbon recovery because they provide greater exposure to hydrocarbon drainage areas. In the same manner, horizontal wells can be used to exploit remaining thin attic oil columns. With brownfield development, operators are challenged to steer their production wells...

... Leg 204 marks the first simultaneous use of coring and logging-while-drilling technologies. The test was conducted in 788.5 m water depth at the crest of southern Hydrate Ridge (Site 1249) in July 2002. Eight cores were recovered from Hole 1249B with 32.9% recovery, on average, through a 45 m interval...
