A system and method is provided that determines at least one bottomhole condition during flowback operations in a well that traverses a hydraulically fractured reservoir. The system and method measure fluid properties of fluids produced at a surface-location of the well during the flowback operations. A transient fluid flow simulator determines composition and properties of fluids in the well between the surface-location of the well and at least one bottomhole-location of the well based on the measured fluid properties. At least one bottomhole condition in the well is determined based on the composition and properties of fluids in the well between the surface-location and at least one bottomhole-location of the well.

System and method for determining bottomhole conditions during flowback operations of a shale reservoir

Fracture monitoring and characterization of a subterranean fracturing process is described. Hydraulic fracturing conditions intended to induce tensile crack opening or compressional crack closure of a fracture responsible for a microseismic event in the Earth formation are selected and a hydraulic fracturing operation is performed using the selected conditions to cause tensile crack opening or compressional crack closure of the fracture responsible for a microseismic event in the Earth formation. Induced motion data from the microseismic event is received using a plurality of receivers, and the received data is analyzed to track the development of the fracture responsible for the microseismic event and/or to track a proppant distribution within the fracture.

Fracture monitoring and characterisation

An apparatus comprising a downhole tool configured for conveyance within a borehole penetrating a subterranean formation, wherein the downhole tool comprises: a probe assembly configured to seal a region of a wall of the borehole; a perforator configured to penetrate a portion of the sealed region of the borehole wall by projecting through the probe assembly; a fluid chamber comprising a fluid; and a pump configured to inject the fluid from the fluid chamber into the formation through the perforator.

Apparatus and methods for characterizing a reservoir

An apparatus for downhole operation. The apparatus comprising a support body having a surface located in a borehole and a coating on an at least a portion of the surface of the support body. The coating is an inert material selected for reducing friction and corrosion.

Durability of downhole tools

A method for displaying geologic stress includes determining magnitudes and directions of principal stresses at at least one a selected location. An analog symbol is generated for each magnitude and direction of the principal stresses. The analog symbols include a magnitude descriptor and a direction descriptor. The analog symbols are stored or displayed.

Method for displaying geologic stress information and its application to geologic interpretation

The invention describes a method of lining a well using expandable tubing including the steps of lowering a expandable tubing in a well bore; injecting a sealant composition into said well; letting the sealant composition solidify into a deformable matrix embedding at least a bottom section of said tubing within said well; and expanding the tubing. The invention allows the creation of a high quality seal at the shoe of the expandable casing because the deformable material is highly stressed by the expansion, and it also allows for the rest of the casing to be properly supported and protected by conventional cement, without incurring excessive wait-on-cement times.

Method of cementing expandable well tubing

Methods and tools are described to reduce sanding including the steps of fracturing the cement sheath in a localized zone around the casing and having the fractured zone act as sand filter between the formation and openings in the casing, with the openings being best pre-formed but temporarily blocked so as to allow a conventional primary cementing of the casing. The fracturing step can also be used for remedial operation to reopen blocked formation or screens.

Methods and apparatus for completing a well

The present invention provides for an apparatus and method to displace fluids and to prevent the mixing or bypassing of fluids used in gravel pack operations. A moveable plug is used to create a physical partition between fluids.

Method and apparatus to isolate fluids during gravel pack operations

Hydraulic fracture dimensions and, optionally, fracture closure pressure and time are determined by adding particulate matter that discharges to create an acoustic signal to the proppant, allowing the particulate matter to discharge, and detecting the acoustic signal with geophones or accelerometers. The particulate matter may be spheres or fibers. The discharge may be explosion, implosion, detonation, or rapid combustion or ignition. The discharge may be triggered by fracture closure or by chemical reaction.
