20080264641 | Blending Fracturing Gel - The present disclosure relates to a system and method for producing a well-fracturing gel using a gel concentrate such that the method and system are capable of timely adjusting the properties of the gel on the fly just prior to introducing the gel into the well. Further, the present disclosure provides for producing a gel with an overall shorter production time as well as adjusting the properties of the gel just prior to injecting the gel into the well. | 10-30-2008 |
20090057237 | Mobile systems and methods of sufficiently treating water so that the treated water may be utilized in well-treatment operations - A system is provided that includes: (a) a mobile platform; (b) an input pump operatively connected to be capable of pumping a treatment stream through the system; (c) a centrifugal separator operatively connected downstream of the input pump to centrifugally treat the treatment stream; (d) a borate filter operatively connected downstream of the centrifugal separator to filter the treatment stream capable of removing at least some of a borate when the treatment stream is at a pH of 8 or above; and (e) a chemical-additive subsystem operatively connected to be capable of: (i) selectively adding one or more chemical agents to the treatment stream upstream of the centrifugal separator, wherein the chemical agents can be selected to be capable of precipitating dissolved ions selected from the group consisting of: sulfate, calcium, strontium, or barium, magnesium, iron; and (ii) selectively adding a chemical agent to the treatment stream upstream of the borate filter to increase the pH of the treatment stream to 8 or above. | 03-05-2009 |
20090062156 | Methods of treating a subterranean formation including a biocidal treatment - A method of treating a subterranean formation including with a bactericidal fluid is provided. The method comprises the steps of: (a) continuously mixing to obtain a stream of a treatment fluid: (i) a base fluid comprising water; (ii) an aqueous solution comprising a hypochlorite having a pH equal to or greater than 7; and (iii) a pH-adjusting agent selected to be capable of lowering the pH of water to less than 7; and (b) injecting the treatment fluid into a wellbore. The step of continuously mixing the base fluid, the aqueous solution of hypochlorite, and the pH-adjusting agent is preferably under conditions and in proportions sufficient to obtain a stream of a treatment fluid having a free chlorine concentration of at least 1 ppm by weight of the water in the treatment fluid and having a pH in the range of 4-7. | 03-05-2009 |
