摘要： A process for removing sulfate includes combining a calcium compound and a fluid comprising sulfate to form a composition; adjusting the pH to be greater than or equal to 12; introducing, to the composition, an electrode comprising aluminum or a noble metal; contacting the composition with a material comprising aluminum if aluminum is absent from the electrode; applying a voltage to the electrode to oxidize the aluminum and to form aluminum ions; contacting the composition with the aluminum ions; and forming a precipitate to remove sulfate from the composition, the precipitate having a crystal structure including calcium, aluminum, and sulfate. A system for removing sulfate includes a first container to receive a composition comprising a calcium compound and a fluid comprising sulfate; a first transfer member to communicate the composition to a second container that includes a first electrode of and a second electrode to produce a precipitate of calcium, aluminum, and sulfate; and a second transfer member to communicate the precipitate and composition to a third container.

摘要： A method of assessing environmental performance includes: receiving, by a processing device, input data related to aspects of an energy industry operation; estimating a first environmental impact of the operation based on the input data; selecting an alternative implementation of the operation; estimating a second environmental impact of the alternative implementation; comparing the first environmental impact and the second environmental impact; and generating an output based on the comparison, the output indicating a change in environmental impact associated with replacing the operation with the alternative implementation.

摘要： Hydraulic fracturing, acidizing and polymer injection using coiled tubing are commonly used techniques in wellbore completion. A pulsed neutron tool may be conveyed at the bottom of the coiled tubing to monitor the effectiveness of these operations by measuring the flow velocity of the borehole fluid of the annulus between the pulsed neutron tool and the borehole wall. Gamma rays resulting from Oxygen activation and/or Σ measurements are used for measuring the flow velocity.
