a wellhead device comprising a lower portion that is in communication with a well and configured to receive a mixed fluid produced therefrom, wherein the wellhead device also comprises an upper portion that is physically separated from the lower portion such that the upper portion is not in direct communication with the well; and

a sand separation device coupled to and external from the wellhead device, wherein the sand separation device is configured to receive the mixed fluid from the well via the wellhead device, separate at least some solids from the mixed fluid to produce a separated fluid, and provide at least some of the separated fluid back to the wellhead device;

a sand storage tank in communication with the sand separation device, wherein the sand storage tank is configured to receive the solids from the sand separation device;

a bypass line extending from the sand storage tank; and

a separator skid, wherein a recovered fluid from the sand storage tank flows through the bypass line and is combined with the separated fluid from the upper portion of the wellhead device to produce a combined fluid that is introduced to the separator skid.
