Definitions

  • various fluids are typically used in the well for a variety of functions.
  • the fluids may be circulated through a drill pipe and drill bit into the wellbore, and then may subsequently flow upward through the wellbore to the surface.
  • the drilling fluid may act to remove drill cuttings from the bottom of the hole to the surface, to suspend cuttings and weighting material when circulation is interrupted, to control subsurface pressures, to maintain the integrity of the wellbore until the well section is cased and cemented, to isolate the fluids from the formation by providing sufficient hydrostatic pressure to prevent the ingress of formation fluids into the wellbore, to cool and lubricate the drill string and bit, and/or to maximize penetration rate.
  • Wellbore fluids may also be used to provide sufficient hydrostatic pressure in the well to prevent the influx and efflux of formation fluids and wellbore fluids, respectively.
  • the pore pressure the pressure in the formation pore space provided by the formation fluids
  • the formation fluids tend to flow from the formation into the open wellbore. Therefore, the pressure in the open wellbore is typically maintained at a higher pressure than the pore pressure. While it is highly advantageous to maintain the wellbore pressures above the pore pressure, on the other hand, if the pressure exerted by the wellbore fluids exceeds the fracture resistance of the formation, a formation fracture and thus induced mud losses may occur.
  • Fluid compositions may be water- or oil-based and may comprise weighting agents, surfactants, proppants, viscosifiers, fluid loss additives, and polymers.
  • weighting agents for a wellbore fluid to perform all of its functions and allow wellbore operations to continue, the fluid must stay in the borehole. Frequently, undesirable formation conditions are encountered in which substantial amounts or, in some cases, practically all of the wellbore fluid may be lost to the formation. For example, wellbore fluid can leave the borehole through large or small fissures or fractures in the formation or through a highly porous rock matrix surrounding the borehole.
  • Lost circulation is a recurring drilling problem, characterized by loss of drilling mud into downhole formations.
  • lost circulation may remain an issue for other wellbore fluids such as including completion, drill-in, production fluid, etc.
  • Fluid loss can occur naturally in earthen formations that are fractured, highly permeable, porous, cavernous, or vugular. These earth formations can include shale, sands, gravel, shell beds, reef deposits, limestone, dolomite, and chalk, among others.
  • Lost circulation may result from induced pressure during drilling. Specifically, induced mud losses may occur when the mud weight, required for well control and to maintain a stable wellbore, exceeds the fracture resistance of the formations.
  • induced mud losses may occur when the mud weight, required for well control and to maintain a stable wellbore, exceeds the fracture resistance of the formations.
  • a particularly challenging situation arises in depleted reservoirs, in which the drop in pore pressure weakens hydrocarbon-bearing rocks, but neighboring or inter-bedded low permeability rocks, such as shales, maintain their pore pressure. This can make the drilling of certain depleted zones impossible because the mud weight required to support the shale exceeds the fracture resistance of nearby zones composed of weakly consolidated sands and silts.
  • Another unintentional method by which lost circulation can result is through the inability to remove low and high gravity solids from fluids.
  • embodiments of the present disclosure are directed to wellbore fluid compositions containing a base fluid; at least one synthetic fiber; and a particulate solid.
  • embodiments of the present disclosure are directed to methods of strengthening a wellbore or reducing fluid loss in a downhole formation that include: preparing a fluid composition, wherein the fluid loss composition contains a base fluid, one or more synthetic fibers, and one or more particulate solids; and emplacing the fluid loss composition in an interval of the downhole formation.
  • embodiments of the present disclosure are directed to methods of strengthening a wellbore or reducing fluid loss into a downhole formation that include: introducing into the wellbore a fluid composition comprising one or more synthetic fibers; and introducing a second fluid composition comprising one or more particulate solids.
  • Embodiments disclosed herein relate to engineered fluid loss control and wellbore strengthening compositions.
  • embodiments disclosed herein relate to fluid compositions that may enter weakly consolidated intervals of the formation, leaving behind a filtercake, plug, or seal that reduces the loss of fluids into the formation.
  • fluid compositions containing engineered combinations of fibrous materials may provide an immediate blockage, preventing further fluid loss and facilitating further drilling operations.
  • the materials may interact synergistically to form a seal that arrests the flow of wellbore fluids into the formation.
  • fiber and fibrous are used to denote a high aspect ratio molecular or macromolecular structure, which may have a length greater than either its diameter or width.
  • the fibers trap and entangle other particles present in the surrounding fluid, creating an impermeable barrier that prevents further fluid loss to the formation.
  • These fibers may act to create a heterogeneous three-dimensional network that can trap particulates of varying sizes, generating a filtercake that prevents fluid flow in or out of the wellbore. Because of the interweaving of the network created by synthetic fibers and particulate solids, a synergistic effect is achieved where reduced amounts of each of the individual components are necessary to reduce fluid losses downhole and/or strengthen the formation.
  • the overall reduction of materials incorporated into the fluids allows the formulation of a wellbore fluid effective in preventing fluid loss and/or strengthen the formation that is still pumpable through standard delivery means such as drill strings and coiled tubing, as opposed to specialized delivery methods normally required to emplace concentrated slurries in thief zones or fluid loss sites.
  • the fluid composition may include a synthetic fiber and a particulate solid.
  • fluid compositions may include a number of other additives known to those of ordinary skill in the art of wellbore fluid formulations, such as wetting agents, viscosifiers, surfactants, dispersants, interfacial tension reducers, pH buffers, mutual solvents, thinners, thinning agents, gelling agents, rheological additives and cleaning agents.
  • wellbore fluid compositions in accordance with the instant disclosure may be applied to an interval of a wellbore as a fluid "pill.”
  • the term "pill” is used to refer to a relatively small quantity (typically less than 200 bbl) of a special blend of wellbore fluid to accomplish a specific task that the regular wellbore fluid cannot perform.
  • the fluid composition may be used to plug thief zones or other regions where circulating fluids are being lost into the formation.
