System and method for hydrostatic bearings

A system, comprising:

• a hydraulic transfer system configured to exchange pressures between a first fluid and a second fluid, wherein the first fluid has a first pressure and the second fluid has a second pressure, and wherein the first pressure is higher than the second pressure, comprising:
• a cylindrical rotor configured to rotate circumferentially about a rotational axis, the cylindrical rotor defining a first end face and a second end face, wherein the first end face is opposite the second end face;
• and
• a hydrostatic bearing system configured to utilize a bearing fluid at a pressure higher than the second pressure of the second fluid to resist axial displacement, radial displacement, or both axial and radial displacement of the cylindrical rotor, the hydrostatic bearing system comprises:
• a first end cover comprising a first surface that interfaces with the first end face of the cylindrical rotor and a first circumferential side surface, the first end cover defines a first plurality of axial apertures that extend into the first surface and a first plurality of radial apertures that extend into the first circumferential side surface, wherein the first plurality of axial apertures fluidly connect to the first plurality of radial apertures within the first end cover, wherein the first plurality of radial apertures are configured to receive the bearing fluid and direct the bearing fluid to the first plurality of axial apertures.

A rotary isobaric pressure exchanger configured to exchange pressures between a first fluid and a second fluid, wherein the first fluid has a first pressure and the second fluid has a second pressure, and wherein the first pressure is higher than the second pressure, the rotary isobaric pressure exchanger comprising:

• a cylindrical rotor configured to rotate circumferentially about a rotational axis, the cylindrical rotor defining a first end face and a second end face, wherein the first end face is opposite the second end face;
