Abstract: A method for hydraulically fracturing a subterranean reservoir. A fracturing fluid comprising a clay stabilizer is provided at an uphole temperature. The uphole temperature allows the fracturing fluid to be for provided at a downhole temperature in the reservoir greater than a cloud point of hydrocarbons in the reservoir. The fracturing fluid is injected into the reservoir at a controlled injection rate to propagate a fracture in the reservoir and mitigate vertical height growth of the fracture. Proppant is introduced into the fracturing fluid to provide a fracturing slurry. The fracturing slurry is injected into the reservoir at the controlled injection rate to prop the fracture.

Abstract: An adsorbent unit for a refrigerant accumulator having a housing with a bottom wall and a side wall and a U-shaped pipe with a return bend adjacent the bottom wall and with first and second pipe portions extending from the return bend along the side wall, and a filter body extending outwardly from the return bend, the adsorbent unit including a porous adsorbent container, adsorbent in the container, first and second end portions on the container, a first tab extending outwardly from the first end portion of the container, an elongated slot in the first tab mounting it on the first and second pipe portions, a second tab extending outwardly from the second end portion of the container, an aperture on the second tab mounting it on the filter body, and a separate compartment on the adsorbent unit containing a refrigerant tracer dye.
