Methods and systems for measuring neutron sigma of downhole reservoir as a function of time for a predetermined testing volume are disclosed. The methods and systems of the present invention analyze the testing volume while maintaining the formation in the testing volume in an unchanged and undamaged state and while dynamically flowing fluids in and out of the testing volume. The systems and methods of the present invention are especially important in determining petrophysical information about the reservoir as well as the in-situ effect of substances on enhanced oil recovery.

Systems and methods for monitoring changes in a formation while dynamically flowing fluids

Methods and systems for collecting high quality reservoir samples and determining producibility of those samples are disclosed that provide for a non-stop and no shock sampling process. The systems and methods of the present disclosure are especially important collecting samples of reservoir samples in a manner that most closely resembles production fluids and maintains the reservoir at or near the draw down pressure during the pumping and sampling processes.

Apparatus and methods for tools for collecting high quality reservoir samples

Methods and systems for delivering EOR substances and determining their efficiency in real time, or near real time, are disclosed. The systems and methods of the present disclosure are especially important in determining petrophysical information about the reservoir as well as the in-situ effect of substances on enhanced oil recovery.

Apparatus and methods for evaluating formations

Method for determining the density (D) of a multiphase fluid (F) flowing through a pipe () and containing a gas (G) which determines a fluctuation of the actual instantaneous density of the fluid (F), said method comprising the following steps: defining a series of consecutive time periods (S, S) which are shorter than the time length corresponding to the highest frequency-component of the fluctuation of the actual instantaneous density; conveying through a section () of the pipe () a photon beam () suited to undergo an attenuation while crossing the fluid (F); counting the actual number (A) of photons of the beam () which cross the pipe () during a first time period (S) of the series; calculating a corrected count (C) as the weighted average value of the actual count (A) and of the corrected count (C) calculated for the preceding time period (S); converting the value of the corrected count (C) into a corresponding value of the density (D) of the multiphase fluid (F) for the first time period (S) through a predefined function.
