Abstract: Methods, systems, and computer readable storage mediums for managing downhole operations are disclosed. To manage downhole operations, the temperatures of various components of tools used in downhole environments may be taken into account. To preserve the life of the components of the tools, cooling flows may be used to retain temperatures of the components within operating ranges. By retaining the temperatures of the components within the operating ranges, the components may be less likely to become damaged, become impaired, and/or operate in undesired manners.

Abstract: Embodiments presented provide for formation testing in geological stratum that exhibit low permeability. In embodiments, a drill pipe supplied acid and/or proppant is injected into the low permeability stratum through action of a formation tester, thereby altering the permeability of the geological stratum.

Abstract: Methods and systems for conveying a WFT via drill pipe within a wellbore penetrating a subterranean formation and setting two packers of the WFT on opposite sides of a zone of interest of the formation, thereby isolating an interval of an annulus between the WFT and a wall of the wellbore. DTT of the formation is then performed by operating two WFT pumps of the WFT to pump fluid from the formation via the isolated interval, through the WFT, and out of the WFT to the wellbore, while operating mud pumps to pump drilling mud into the wellbore and thereby convey a mixture of the drilling mud and the pumped formation fluid through the annulus to a mud gas separator. Gas from the mud gas separator is used to measure a surface production rate of the formation fluid.
