Method for selecting the location of a simulating geothermal well

The present invention provides a method for selecting the location of a stimulating well, comprising the steps of conducting a geological study of a field containing a geothermal hydrothermal resource by operating geological useful equipment, determining a maximum horizontal stress line within said field by means of a device, generating a map of existing wells including a plurality of sub-commercial wells within said field relative to said maximum horizontal stress line, measuring a distance between each of said sub-commercial wells and the maximum horizontal stress line, determining that those sub-commercial wells aligned with, or located relatively close to the maximum horizontal stress line are stimulatable, and selecting a location of a stimulating well for stimulating the stimulatable well that is separated less than an anticipated fracture propagating distance from said stimulatable well.. .

Compound cluster placement in fractures

Proppant cluster placement in fractures with foamed carrying fluid. A formation treatment method includes injecting a treatment fluid stage, having a particulate-containing substage containing a self-agglomerating solid composition and a foamed carrying fluid, above a fracturing pressure, and alternating pulses of a pumping parameter to transform the self-agglomerating composition into a channelized solids pack, and closing the fracture.

Compound cluster placement in fractures

Compound cluster placement in fractures. A fracture treatment method includes forming propped regions having a larger coverage area than channels between the propped regions, and channelizing the propped regions in situ.

Well treatment method and system

An in situ channelization method, treatment fluid and system for stagewise reduction of the treatment fluid viscosity. A method involves injecting a treatment fluid into a fracture, decrosslinking a polymer in a first viscosity reduction stage to trigger channelization of a first solid particulate in the fracture prior to closure, and completing a break of the polymer following fracture closure.

Well injection and production method and system

A method and system for enhancing petroleum production are provided, in which petroleum is displaced from a fractured formation by selectively injecting fluid into selected fractures in the formation without injecting into the other non-selected fractures. The injected fluid flows out into the fractured formation and enhances recovery from the non-selected fractures.

Mud motor bearing pack lower end with catch ring

It is desirable to secure a lower end of a down hole assembly in the event of a down hole failure, such as a fractured drive shaft, enabling recovery of the bottom hole assembly and drill bit. To secure the lower end of the down hole assembly, a catch apparatus according to embodiments herein may be used, the catch apparatus including a rotating bearing having a distal end threadably coupled to a distal portion of a drive shaft.

Heterogeneous proppant placement in a fracture with removable channelant fill

A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) wherein the proppant comprises from 1 to 100 percent in weight of stiff, low-elasticity and low-deformability elongated particles (34) and proppant-spacing filler material called a channelant (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the channelant (24), and removing the channelant filler material (24) to form open channels (26) around the pillars (28) for fluid flow from the formation (14) through the fracture (20) toward the wellbore (10).

Glasses having non-frangible stress profiles

A glass exhibiting non-frangible behavior in a region where substantially higher central tension is possible without reaching frangibility is provided. This region allows greater extension of the depth of compression in which fracture-causing flaws are arrested, without rendering the glass frangible despite the presence of high central tension region in the sample..
