Abstract: In an embodiment of the disclosure, mixtures of different carbon length alcohols are used as the primary feedstock for Guerbet alcohols. Specifically, embodiments relate to a method of synthesizing mixed molecular weight additives from a mixture of primary alcohols comprising, receiving a mixture of primary alcohols having greater than two different chain length primary alcohols and reacting the mixture of primary alcohols in a single reactor to produce a mixture of at least five Guerbet alcohols. The mixture of Guerbet alcohols can then be used to produce an additive or surfactant composition comprising additives or surfactants of different molecular weights.

Abstract: The simultaneous control of the two forms of mercury in petroleum reservoirs (elemental and particulate HgS) is accomplished by the use of agents which react with the elemental mercury and bind the particulate HgS to the formation material: a mercury capture agent and a chemical sand control agent. The elemental control agent reacts with and adsorbs the elemental mercury. The chemical sand control agents reduce or eliminate the dislodging of fine particulate mercury from the surface of the formation material. This simultaneous control can be applied for a new well during well completion operations wherein analyses indicate the presence of mercury. This simultaneous control can also be applied to a currently producing well during a work-over when mercury is detected in the gas or crude products.
