Definitions

  • Formations may exert much higher point or line loadings than anticipated on the basis of compressive strength estimates, and those loadings may induce the desired cracking as well.
  • compressive strength of the mortar can be selected based on a number of factors, including extent of cracking or permeability desired, cost of materials, flowability, well choke policy, and the like.
  • the mortar slurry may provide the mortar with the minimum level of conductivity without resorting to certain materials that may be expensive, harmful to the environment, difficult to transport, or otherwise undesirable.
  • the mortar slurry may essentially exclude certain materials.
  • gelling agents, breakers, foaming agents, surfactants, additional viscofiers, and/or degradable materials may be entirely omitted from the mortar slurry, or included in only minimal amounts.
  • the mortar slurry may include less than 5% gelling agents, less than 5% foaming agents, less than 5% surfactants, and/or less than 5% degradable material based on the weight of the cementitious material in the mortar slurry.
  • a simple manifold may allow a pump system for cement, hydraulic fracturing or mud system for placement of the cement.
  • the cement at this stage could be mixed at real time "on the fly” in cementing mixing equipment for oil and gas applications or could have been batch mixed and properly delayed while providing movement to avoid setting. This may be done by construction cement trucks that may then pour the cement into the hoppers of the mud pumps. These trucks may have received the cement from a cement batch mixing plant on the well location, nearby or at the cement manufacturing site. After the cement is placed in the formation and applying if needed the most appropriate near wellbore conductivity enhancement technique and diversion, the cement may be displaced in the wellbore. This may be achieved through pressure or with a heavy brine if pumping power is limited.
  • a tendency for cement slurry or mortar slurries to separate may be indicated by results of an API Free Fluid test, or an API Sedimentation test.
  • fractures could be initiated by placing a mortar slurry in the wellbore using, for example, a coiled tubing, where the slurry could be placed in the casing from the bottom displacing wellbore fluids upward.
  • the mortar slurry could be put into the casing by bullheading the mortar slurry from the surface.
  • bullheading it is meant that the fluids are pumped into the casing at a pressure that is sufficient to force the wellbore fluids to fracture the formation and enter the subterranean formation through the fractures.
  • the second wire line controllable valves may be provided in close proximity to the first wire line controllable valves with which they are associated.
  • the volume between the first wire line controllable valve and the second wire line controllable valve could fill with proppant during the fracturing process because inertia of the solid proppants may carry them past the opening into the fracture and accumulate in the volume past this opening. This volume may therefore be minimized to reduce an amount of proppant that may remain in the wellbore after the fracturing operation is completed.
  • the valve to provide communication form inside the wellbore to outside of the wellbore adjacent to the first fracture could be opened, and the valve associated with it to isolate a portion of the inside of the wellbore upstream from the first valves from a portion of the inside of the wellbore down-stream of the first valve could be closed.
  • a wire line conveyed tool such as a commercially available wire-line kick-over tool.

Abstract

On décrit divers procédés de fracturation d'une formation dans lesquels une suspension de mortier est utilisée pour réduire l'impact sur l'environnement. Un procédé met en oeuvre des pompes basse pression pour réduire l'encombrement. Un autre procédé permet de capturer le dioxyde de carbone. Un autre procédé encore permet d'atténuer la sismicité liée aux activités pétrolières et gazières.
