Wellhead platform systems for use in extracting and testing multi-phase raw mixtures

A system for use in a wellhead platform to extract multi-phase raw mixtures via a plurality of wellheads and provide same to an export line, the system comprising:

• a controller operable to dynamically configure the system to be in one of a well testing mode, a low pressure mode, or an unloading mode based on at least a received wellhead flowing pressure (WHFP) measurement, wherein:
• the well testing mode is configured when the WHFP is between about 3 to 60 barg;
• the low pressure mode is configured when the WHFP is between about 3 to 20 barg;
• and
• the unloading mode is configured when the WHFP is equal to or less than about 3 to 5 barg;
• a separator subsystem including:
• a separator assembly having a separator inlet section for receiving the extracted multi-phase raw mixtures, a separator container body for housing the received multi-phase raw mixture, a separator gas outlet section for separating gas, and a separator liquid outlet section for separating liquid, wherein the separator gas outlet section is configurable by the controller to provide gas directly to the export line when in the well testing mode;
• a separator blowcase assembly having a separator blowcase container body, a separator blowcase liquid inlet section connected to the separator liquid outlet section for receiving liquid into the separator blowcase container body, a separator blowcase liquid outlet section, and a separator blowcase gas inlet section;
• a scrubber subsystem including:
• a scrubber assembly having a scrubber inlet section, a scrubber container body, a scrubber gas outlet section for separating gas, and a scrubber liquid outlet section for separating liquid, wherein:
• the scrubber inlet section is configurable by the controller to receive gas directly from the separator gas outlet section when in the low pressure mode;
• and
• the scrubber inlet section is configurable by the controller to receive gas directly from the export line when in the unloading mode;
• and
• a scrubber blowcase assembly having a scrubber blowcase container body, a scrubber blowcase liquid inlet section connected to the scrubber liquid outlet section for receiving liquid into the scrubber blowcase container body, a scrubber blowcase liquid outlet section, and a scrubber blowcase gas inlet section;
• a first stage compressor subsystem comprising a first stage compressor gas inlet section, a first stage compressor for compressing gas, and a first stage compressor gas outlet section, wherein the first stage compressor gas inlet section is configurable by the controller to receive gas from the scrubber gas outlet section, the first stage compressor is configurable to compress the received gas, and the first stage compressor gas outlet section is configurable to output the compressed gas when in the low pressure mode or the unloading mode;
• and
• a second stage compressor subsystem comprising a second stage compressor gas inlet section, a second stage compressor, and a second stage compressor gas outlet section, wherein the second stage compressor gas inlet section is configurable by the controller to receive gas from the first stage compressor outlet section, the second stage compressor is configurable to further compress the received compressed gas, and the second stage compressor gas outlet section is configurable to output the further compressed gas to the separator blowcase gas inlet section and the scrubber blowcase gas inlet section when in the low pressure mode or the unloading mode.
