  • Patent number: 9721220
    Abstract: 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.

  • Publication number: 20170044035
    Abstract: A process for treating oilfield wastewater comprises oxidizing an oilfield wastewater having greater than about 1 ppm of a reducing agent comprising ferrous ions, a sulfide, a bisulfide, an organic compound, or a combination comprising at least one of the foregoing with an oxidant comprising hydrogen peroxide, potassium permanganate, chlorine, sodium hypochlorite, calcium hypochlorite, sodium percarbonate, sodium perborate, ozone, UV, oxygen, or a combination comprising at least one of the foregoing to provide an oxidized wastewater; and combining the oxidized wastewater with a biocide comprising chlorine dioxide.

  • Publication number: 20150053619
    Abstract: Both the hardness and boron content of wastewater may be reduced by contacting the wastewater with liquid sodium silicate (LSS) in an effective amount for such reductions followed by one or both of two additional procedures. The additional procedure may be contacting the wastewater with an Al(3+)-containing compound in an amount effective to at least partially remove silicon from the wastewater, where the contacting is before, during or after the wastewater is contacted with LSS. The second additional or alternative procedure involves, subsequent to contacting the wastewater with LSS, treating the untreated water with an electrocoagulation (EC) apparatus for a period of time effective to at least partially remove silicon from the wastewater. The EC procedure may also further remove boron from the wastewater.

  • Publication number: 20140339162
    Abstract: Electrocoagulation (EC) may remove oil and solids from oilfield water and other raw, untreated or unprocessed water as a pretreatment for increased boron removal efficiency using a subsequent boron selective resin. Boron selective resins are efficient for boron removal, but oil and solids in water lower the boron remove efficiency and capacity.

  • Publication number: 20140246371
    Abstract: 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.

  • Publication number: 20130020075
    Abstract: 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 ? measurements are used for measuring the flow velocity.
