Publication number: 20240066512Abstract: A method of utilizing humic acid to prepare layered humic acid/manganese oxide composite catalyst and its application, the method includes the steps of: adding sodium hypochlorite, manganese salt and humic acid to a water source, stirring and mixing; then introducing into a filter device having a filter material of manganese and a support medium, and generating a layered humic acid/manganese oxide composite catalyst on a surface of the filter material while directing a continuous water flow of the water source into the filter device with a short empty bed contact time for a short time. The catalyst can be used to effectively remove manganese to maintain an effluent with a Mn2+ concentration of not more than 20 ?g/L and to effectively remove heavy metals such as iron, manganese, arsenic, thallium, molybdenum or lead from the water source under neutral, acidic or alkaline conditions with a removal rate of 95% more.Type: ApplicationFiled: August 31, 2023Publication date: February 29, 2024Inventors: Panpan WANG, Han WANG, Jun MA, Shiyi QIU, Junda YI

Patent number: 9290689Abstract: A process of making observations of a subterranean reservoir penetrated by a wellbore uses distinguishable sets of tracer particles and comprises steps of: (i) delivering a plurality of sets of tracer particles to respective subterranean locations via the wellbore, the particles in each set comprising a tracer substance which distinguishes that set form the other sets; (ii) causing or allowing the tracer substances to flow out from the tracer particles whilst the particles are at the respective subterranean locations; (iii) causing or allowing production of fluid out of said reservoir via the wellbore; and (iv) detecting the presence or absence of the tracer substances in the produced fluid. The tracer substances are sufficiently distinguishable from each other to enable a tracer substance detected in the produced fluid to identify the set of tracer particles from which it has come and hence identify the location from which it has come.Type: GrantFiled: June 3, 2009Date of Patent: March 22, 2016Assignee: Schlumberger Technology CorporationInventors: Valerie Lafitte, Trevor Hughes, Slaheddine Kefi, Matthew Miller, Gary Tustin, Shiyi Wang

Patent number: 8695708Abstract: A method for treating a subterranean formation penetrated by a wellbore is provided. The method includes providing a treatment fluid containing a viscoelastic surfactant having at least one degradable linkage, a hydrolysable material, and a pH control material, and injecting the treatment fluid into a subterranean formation. The pH control material may have a pH equal or greater than about 9 and may include a strongly alkaline material and an oxidizing agent.Type: GrantFiled: September 1, 2010Date of Patent: April 15, 2014Assignee: Schlumberger Technology CorporationInventors: Andrey Fedorov, Olesya Levanyuk, Tatiana Zolnikova, Vadim Khlestkin, Alexander Nadeev, Diankui Fu, Bruno Lecerf, Shiyi Wang, Gary John Tustin, Valerie Lafitte

Patent number: 8688383Abstract: The magnitude of asphaltic precipitation when injecting a viscosity reducing diluent into a reservoir formation, notably to assist oil recovery therefrom, is forecast by (i) determining a relationship between asphaltic precipitation and a solubility parameter for the diluted oil, and then (ii) utilizing that relationship to forecast the magnitude of asphaltic precipitation when injecting a predetermined viscosity reducing diluent into the formation. Making this forecast may be followed by injecting a viscosity reducing diluent into the formation to assist oil recovery. The diluent may in particular be supercritical carbon dioxide or other asphaltene precipitant mixed with a more polar material in proportions designed by forecasting asphaltic precipitation by candidate materials in possible proportions.Type: GrantFiled: April 23, 2009Date of Patent: April 1, 2014Assignee: Sclumberger Technology CorporationInventors: Trevor Hughes, Gary Tustin, Alexander Wilson, Carlos Abad, Shiyi Wang

Patent number: 8393395Abstract: A process for hydraulic fracturing of a subterranean reservoir formation penetrated by a wellbore includes pumping a fracturing fluid or other aqueous fluid from the surface via the wellbore and into the reservoir. This fluid is an aqueous suspension of particles which each comprise an oilfield chemical distributed within an encapsulating matrix of water-insoluble carrier material. The encapsulating matrix is chosen so as to provide a delayed release of the oilfield chemical from the particles into surrounding fluid, such that oilfield chemical is liberated from the particles after they have entered the fracture. The encapsulating matrix may be a polymer which is at least partially amorphous, with a glass transition temperature below the reservoir temperature.Type: GrantFiled: June 3, 2009Date of Patent: March 12, 2013Assignee: Schlumberger Technology CorporationInventors: Thomas Cochet, Trevor Hughes, Slaheddine Kefi, Valerie Lafitte, Khooi Tan, Gary Tustin, Shiyi Wang
