    摘要： The present invention is a method and apparatus for real time in-situ measuring of the downhole chemical and or physical properties of a core of an earth formation during a coring operation. The present invention comprises several embodiments that may use electromagnetic, acoustic, fluid and differential pressure, temperature, gamma and x-ray, neutron radiation, nuclear magnetic resonance, and mudwater invasion measurements to measure the chemical and or physical properties of the core that may include porosity, bulk density, mineralogy, and fluid saturations. The present invention comprises a downhole apparatus coupled to an inner and or an outer core barrel near the coring bits with a sensor array coupled to the inner core barrel for real time gathering of the measurements. A controller coupled to the sensor array controls the gathering of the measurements and stores the measurements in a measurement storage unit coupled to the controller for retrieval by a computing device for tomographic analysis.

    摘要： The present invention includes a method for treating a hydrocarbon-bearing clastic formation having brine. The method includes contacting the hydrocarbon-bearing clastic formation with a fluid, which at least one of at least partially solubilizes or at least partially displaces the brine in the hydrocarbon-bearing clastic formation, and subsequently contacting the hydrocarbon-bearing clastic formation with a composition. The composition includes a nonionic fluorinated polymeric surfactant and solvent. When the composition is contacting the hydrocarbon-bearing clastic formation, the nonionic fluorinated polymeric surfactant has a cloud point that is above the temperature of the hydrocarbon-bearing clastic formation.

    摘要： A method and apparatus are disclosed for cleaning the wellbore and the near wellbore region. A sonde is provided which is adapted to be lowered into a borehole and which includes a plurality of acoustic transducers arranged around the sonde. Electrical power provided by a cable is converted to acoustic energy. The high intensity acoustic energy directed to the borehole wall and into the near wellbore region, redissolves or resuspends the material which is reducing the permeability of the formation and/or restricting flow in the wellbore.
