Downhole phase separation in deviated wells

A system comprising:

• a packer configured to be disposed in a deviated portion of a well formed in a subterranean formation, the packer configured to form a seal with an inner wall of the well;
• a first tubular extending through the packer and having a cross-sectional flow area that is smaller than a cross-sectional flow area of the well, the first tubular comprising:
• a first inlet configured to receive a wellbore fluid;
• and
• a first outlet portion comprising a first outlet and perforations formed on a side wall of the first tubular adjacent the first outlet, the perforations configured to induce separation of a gaseous portion of the wellbore fluid from a remainder of the wellbore fluid, such that the gaseous portion flows uphole through an annulus between the inner wall of the well and the first tubular;
• a second tubular comprising:
• a second inlet configured to receive at least a liquid portion of the remainder of the wellbore fluid;
• and
• a second outlet configured to discharge the liquid portion of the remainder of the wellbore fluid;
• and
• a connector coupled to the first tubular and the second tubular, wherein:
• the connector is coupled to the first outlet portion of the first tubular, such that the connector is configured to prevent flow of the wellbore fluid from the first tubular through the connector and such that any fluid that flows into the first tubular via the first inlet flows out of the first tubular through the perforations of the outlet portion,
• the connector is configured to fluidically connect the second tubular to a downhole artificial lift system disposed within the well, uphole of the connector, and
• a sump for accumulation of solid material from the wellbore fluid is defined by a region of the annulus between the inner wall of the well and the first tubular, downhole of the second inlet of the second tubular and uphole of the packer.
