  2. Calcium bromide - Wikipedia

    en.wikipedia.org/wiki/Calcium_bromide

    Calcium bromide is the name for compounds with the chemical formula Ca Br 2 (H 2 O) x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate.

  5. Oil-based mud - Wikipedia

    en.wikipedia.org/wiki/Oil-based_mud

    Oil-based mud [1] is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. The oil base can be diesel, kerosene, fuel oil, selected crude oil or mineral oil.

    Brine mining is the extraction of useful materials (chemical elements or compounds) which are naturally dissolved in brine.The brine may be seawater, other surface water, groundwater, or hyper-saline solutions from several industries (e.g., textile industries). [1]

  8. Well stimulation - Wikipedia

    en.wikipedia.org/wiki/Well_stimulation

    Well stimulation is a broad term used to describe the various techniques and well interventions that can be used to restore or enhance the production of hydrocarbons from an oil well. Hydraulic fracturing (fracking) and acidizing are two of the most common methods for well stimulation.

  9. Uses of radioactivity in oil and gas wells - Wikipedia

    The attenuation of these gamma rays gives an accurate measure of formation density; this has been a standard oilfield tool since 1965. Another source is americium berylium (Am-Be) neutron source used in evaluation of the porosity of the formation, and this has been used since 1950. In a drilling context, these sources are used by trained ...
