Publication number: 20180334613Abstract: Methods and systems for enhancing acid fracture conductivity of acid fracture treatments on subterranean formations are provided. An example method of acid fracture treatment includes initiating fracturing of a subterranean formation in which a wellbore is formed to create a formation fracture, after initiating the fracturing for a period of time, injecting an acidic fluid into the wellbore to etch walls of the formation fracture to thereby create fracture conductivity, introducing a gas into the wellbore to foam fluids in the wellbore, and increasing a foam quality of the fluids with time during the treatment. The foam quality is based on a volume of the introduced gas and a total volume of the fluids in the wellbore.Type: ApplicationFiled: July 30, 2018Publication date: November 22, 2018Applicant: Saudi Arabian Oil CompanyInventors: Aslan Bulekbay, Ahmed M.

Patent number: 10113406Abstract: Fracturing a reservoir includes providing a pad fluid to the reservoir via a wellbore in a well to create fractures in the reservoir, providing a fracturing fluid to the fractures via the wellbore, providing a nanosilica carrier fluid to the fractures via the wellbore, activating the nanosilica particles with an activator to yield a nanosilica gel, and shutting in the wellbore at a wellbore pressure, thereby allowing the nanosilica gel to form proppant pillars in the fractures. The nanosilica carrier fluid includes nanosilica particles, and providing the nanosilica carrier fluid to the fractures comprises pulsing quantities of the nanosilica carrier fluid into a continuous flow of the fracturing fluid or alternately pulsing quantities of the nanosilica carrier fluid and the fracturing fluid. An elapsed time between pulsing the quantities of the nanosilica carrier fluid is between 2 seconds and 10 minutes.Type: GrantFiled: September 21, 2017Date of Patent: October 30, 2018Assignee: Saudi Arabian Oil CompanyInventors: Ahmed M.

Publication number: 20180230789Abstract: A method of enhancing conductivity within a hydrocarbon-bearing reservoir by building proppant pillars in a spatial arrangement in fractures created or enlarged in the reservoir. Two fluids of differing stability are simultaneously pumped into the reservoir. The fluids may contain identical proppant mixtures which include a first proppant which has an apparent specific gravity less than the apparent specific gravity of a second proppant. The fluids may contain identical proppants mixtures where the average particle size of a first proppant is greater than the average particle size of a second proppant. Vertically extending pillars are created within the formation when the fluids are destabilized and the first proppant is then released from the destabilized fluids. The area between the pillars may be held open by the presence of the second proppant in the remaining fluid.Type: ApplicationFiled: February 26, 2018Publication date: August 16, 2018Inventors: D. V. Satyanarayana Gupta, Ahmed M. Gomaa, Scott Gregory Nelson

Patent number: 9938811Abstract: The flow of well treatment fluids may be diverted from a high permeability zone to a low permeability zone within a fracture network within a subterranean formation by use of a divert system comprising dissolvable diverter particulates and proppant. At least a portion of the high permeability zone is propped open with the proppant of the divert system and at least a portion of the high permeability zone is blocked with the diverter particulates. A fluid is then pumped into the subterranean formation and into a lower permeability zone of the formation farther from the wellbore. The diverter particulates in the high permeability zones may then be dissolved at in-situ reservoir conditions and hydrocarbons produced from the high permeability propped zones of the fracture network. The divert system has particular applicability in the enhancement of production or hydrocarbons from high permeability zones in a fracture network located far field from the wellbore.Type: GrantFiled: July 22, 2016Date of Patent: April 10, 2018Assignee: Baker Hughes, LLCInventors: Naima Bestaoui-Spurr, Ahmed M. Gomaa, Harold Gene Hudson, D. V. Satyanarayana Gupta, Scott Gregory Nelson, Harold Dean Brannon

Patent number: 9902898Abstract: A method of enhancing conductivity within a hydrocarbon-bearing reservoir by building proppant pillars in a spatial arrangement in fractures created or enlarged in the reservoir. Two fluids of differing viscosity and stability are simultaneously pumped into the reservoir. The fluids contain identical proppants which include a proppant which is neutrally buoyant in the fluid and a proppant which is not neutrally buoyant in the fluid. Vertically extending pillars are created within the formation when the fluids are destabilized and the heavier proppant is then released from the destabilized fluids. The area between the pillars may be held open by the presence of the neutrally buoyant proppant in the remaining fluid. Fluid produced from the hydrocarbon-bearing reservoir is then flowed at least partially through channels between the vertically extending pillars.Type: GrantFiled: May 21, 2016Date of Patent: February 27, 2018Assignee: Baker Hughes, a GE company, LLCInventors: Scott Gregory Nelson, Ahmed M.

Publication number: 20160177693Abstract: A diverter fluid includes an aqueous carrier fluid, and a plurality of water-swellable polymer particles having a size of 0.01 to 100,000 micrometers. A method of hydraulically fracturing a subterranean formation penetrated by a reservoir includes injecting a fracturing fluid into the formation at a pressure sufficient to create or enlarge a fracture, injecting a diverter fluid into the formation, and injecting a fracturing fluid into the formation, wherein the flow of the fracturing fluid is impeded by the diverting agent and a surface fracture area of the fracture is increased. A method of controlling the downhole placement of a diverting agent is also disclosed, including injecting a diverter fluid including the diverting agent and an aqueous carrier fluid selected so that the polymer particles are fully swelled after contacting the aqueous carrier fluid for an amount of time sufficient to achieve a desired downhole placement.Type: ApplicationFiled: December 16, 2015Publication date: June 23, 2016Applicant: Baker Hughes IncorporatedInventors: Ahmed M.
