  • Patent number: 11959033
    Abstract: A liquid fuel composition for a spark ignition internal combustion engine comprising (a) gasoline blending components, (b) Fischer-Tropsch derived naphtha at a level of up to 50% v/v and (c) oxygenated hydrocarbon at a level less than 50% v/v. While the low octane number of Fischer-Tropsch derived naphtha would normally severely restrict its blendability in gasoline to low levels, it has now been found that Fischer-Tropsch derived naphtha can be included in, for example, ethanol-containing gasoline fuel compositions, in surprisingly and significantly high blend ratios of Fischer-Tropsch derived naphtha to ethanol.

  • Patent number: 11851976
    Abstract: A downhole tool, which includes a tool housing having a longitudinal axis, is equipped with a sting for punching a hole in a casing wall and injecting a sealant through the hole. The tube has a fluid channel to establish fluid communication from within the tool housing to an exterior of the tool housing through the fluid channel. A press device acts on the sting to force the sting in a radially outward direction from the tool housing. A check valve is arranged in the fluid channel, which allows fluid communication in a direction from within the tool housing to an exterior of the tool housing and which blocks fluid flow in an opposite direction. In use, the sting can perforate a casing wall and the sealant can be injected into an annular space around the casing.
