System for gathering gas from a gas field comprising a high efficient high pressure compressor

A method for controlling a gas mass flow of a system for gathering gas from a gas field, the method comprising:

• measuring an input mass flow at a gas input of a high pressure compressor, wherein the gas input receives the gas gathered from the gas field with a first gas pressure, wherein the high pressure compressor comprises a gas output for providing gas with a second gas pressure to a gas export system, and wherein the second gas pressure is higher than the first gas pressure;
• measuring, by a measuring unit that is coupled to the gas input, an input mass flow value that is indicative of an input mass flow at the gas input;
• receiving, by a mass flow control unit, the measured input mass flow value, wherein a first low pressure compressor is connectable to a first wellhead arrangement of the gas field for receiving the gas from the first wellhead arrangement, wherein the first low pressure compressor is connected to the gas input for providing the gas to the gas input with a first mass flow, wherein a second low pressure compressor is connectable to a second wellhead arrangement of the gas field for receiving the gas from the second wellhead arrangement, and wherein the second low pressure compressor is connected to the gas input for providing the gas to the gas input with a second mass flow;
• and
• controlling, by the mass flow control unit coupled to the gas input, the input mass flow,
• wherein the mass flow control unit is coupled to the measuring unit for receiving the measured input mass flow value, and
• wherein the mass flow control unit is further connected to the first low pressure compressor for controlling the first low pressure compressor and the second low pressure compressor for controlling the second low pressure compressor such that the first mass flow and the second mass flow are controllable for controlling the input mass flow at the gas input such that the measured input mass flow value corresponds to a set point input mass flow value.
