    All core holders are built with high quality stainless steel and can include wetted parts made from Hastelloy C or 316SS. DCI’s core holders for measuring electrical resistivity are electrically isolated and include electrical feed thru for multi-tap measurements (up to 8 electrodes). Other core holders include measuring pressure or temperature gradients along the core. The pressure taps can be combined with the electrodes to make both pressure and resistivity measurements on the same core. A few of the options that can be configured for each core holder are listed below:

    • Core holder type
    • Maximum pressure
    • Maximum temperature
    • Wetted parts
    • Jacket material
    • Number of pore pressure ports
    • Type of confining and pore pressure ports
    • Confining temperature probe

    Because quality is of the utmost importance, all core holders are pressure tested to insure trouble free operation.

    DCI can provide mounting brackets and stands for your core holder. The most popular is a pivoting mount frame that allows for horizontal or vertical orientation of the core holder. Others include roller-supported frames or stands for banks of core holders. There are a number of stand options available.

  • Acoustic Separator/Two Phase Separator   •   Accurate and precise two phase fluid measurements

    The two phase acoustic separator allows for precise volumetric measurements of each phase in the separator. The precision bore tubes and proprietary data reduction techniques provide high accuracy, high resolution data.

    The acoustic separator paired with CFAS™ technology makes an infinite volume two phase separator with back pressure control. CFAS™ technology is one of the most accurate, and economical way to record sample saturation with two phase flow. See the Acoustic Separator/Two phase separator page for more information.

    Precision Measurements

    The two phase acoustic separator consists of two precision bore tubes mounted vertically in a base connection block. One tube acts as a separation tube, where two immiscible fluids of different density separate due to gravitational forces. The second tube is the sensing tube where a meniscus between the two fluids is undisturbed by any flow in the separation tube. The higher density fluid communicates between the two tubes in the base connection block. The lower density fluid communicates through a similar connection block mounted to the top of the two tubes. An acoustic transducer mounted in the base of the sensing tube uses the reflection time of acoustic waves reflected from the meniscus between the two fluids to measure the volume of the higher density fluid in the separator. Proprietary data reduction techniques provide high accuracy, high resolution data.

    Better Design

    DCI uses longer precisely machined bores with smaller diameters to increase resolution. In this design a small change in volume creates a larger increase in reflection time thus giving better resolution and increased accuracy. The electronics for the two phase separator give the user the capability to adjust signal amplitude and trigger level making the most difficult to detect meniscuses easily visible.

    Continuous Flow Acoustic Separator Technology

    DCI’s CFAS™ technology (Patented) incorporates the two phase separator with two VPA syringe pumps to provide highly accurate measurement of the volume of two different phases that are produced in a core flood experiment, even when the volumes of fluids produced exceeds the volume capacity of the two phase separator. In this arrangement, one of the VPAs is operated in external transducer feedback mode, with the analog signal from the two phase separator as the feedback signal. In this mode, the VPA receives any of the higher density fluid that is produced and maintains the meniscus level at a constant level in the separator. Thus, the VPA provides a very accurate measurement of the volume of the higher density fluid that is produced. The second VPA is connected to the upper outlet port of the two phase separator (outlet for the lower density fluid). This VPA operates in a pressure feedback mode, thus controlling the back pressure in the two phase separator, and on the sample in the core flood experiment. Any of the lower density fluid that is produced by the experiment is received by this second VPA, and the volume received is measured precisely. Using dual cylinder syringe pumps in each of these two functions provides the ability to receive infinite volume of either fluid that is produced by the system. This allows volumes of fluid larger than the capacity of the two phase separator to flow through the sample while equilibrium is established, and still maintain a precise measurement of each fluid volume that is produced.

    Software

    Software for the two phase separator is provided with every unit and displays the volume of the lower density fluid as well as graphical representation of fluid levels inside the cylinders. The acoustic separator software is easily integrated into more complex systems such as core flooding programs to keep track of produced fluids and saturation state.

  • Steam Generator   •   High pressure, high temperature steam for EOR core floods

    The Steam Generator produces super-heated steam at temperatures and pressures up to 350°C and 2,500 psi. Temperatures are set using a Watlow controller with digital readout. The controller has an integrated high temperature limit shutdown to protect the system from overheating. Outlet fluid temperature is measured with a thermocouple and can be monitored with the digital panel display. A VPA Syringe Pump or HPLC pump can be incorporated to deliver water through the system. For safety an emergency stop button is present on the front panel.

    The bench top steam generator produces super-heated steam as a standalone unit and can be easily incorporated into any core flooding systems. The system consists of a coiled tube wrapped around a heater cell enclosed in insulation.  The inlet end of the coiled tube connects through a bulkhead to an external pump.  The pump delivers water into the tube at a constant flow rate set by the user.   Pressure is typically controlled by a customer provided back pressure regulator.  There is a thermocouple on the outlet of the coiled tube to measure the temperature of the steam.  This temperature can be read on a display found on the front panel.  The temperature of the steam is controlled using a temperature controller on the front panel.  There is also an emergency stop button on the front panel to shut off power to the heaters immediately if necessary.

    The Gas Booster Cart consists of a gas booster that is mounted to the bottom of a wheeled cart and plumbed to various pressure regulators, valves and gauges which are conveniently mounted on the top of the cart.  The Gas Booster Cart takes bottle pressure gas and boosts it to a higher pressure.  The cart requires 100 psi air to do this.  It can boost gas up to 10,000 psi or 20,000 psi and store up to 2 Liters of boosted gas. The amount of time it takes to boost gas to a higher pressure depends on the starting pressure of the gas, the desired final pressure of the gas and the air delivery capability of the pressurized air source. The boosted gas is connected to a pressure regulator and can be regulated to any required pressure below the boosted gas pressure.  Contact a DCI engineer if different specifications are needed.
