Sample preparation pressure-volume-temperature (pvt) cell for viscosity sample preparation with ectromagnetic viscometer (emv)

A method for determining viscosity of a fluid using a pressure-volume-temperature (PVT) electromagnetic viscometer (EMV) system, comprising:

• receiving, by a sample preparation cell disposed within the PVT EMV system, the fluid from a fluid supply reservoir;
• adjusting, under control of a controller configured to operate the sample preparation cell, temperature system, and EMV, a temperature of a temperature control chamber disposed within the PVT EMV system using the temperature system;
• executing, for each set pressure in a plurality of set pressures, the following steps, wherein each set pressure in the plurality of set pressures is below a bubble point pressure of the fluid:
• adjusting a pressure of the fluid in the sample preparation cell to the set pressure,
• homogenizing the fluid by stirring the fluid with a stirrer disposed within the sample preparation cell,
• degassing the fluid by removing released gases from the sample preparation cell though a venting fluid line in fluid communication with the sample preparation cell and a gas capturing system configured to remove released gases from the sample preparation cell,
• transporting a volume of the fluid from the sample preparation cell to the EMV,
• measuring the viscosity of the volume of the fluid in the EMV,
• transmitting the viscosity measurement to the controller, and
• removing the volume of the fluid from the EMV;
• and
• planning a wellbore to penetrate a hydrocarbon reservoir based on the measured viscosities,
• wherein the planned wellbore comprises a planned wellbore path.
