Abstract: A method and system for determining formation properties based on a fracture treatment that may include collecting data from a fracture treatment for a well. A flow regime of the fracture treatment is determined based on the data. Formation properties may be determined based on the flow regime and the data.

Abstract: A system for monitoring a wellbore service treatment, comprising a downhole tool operable to perform the wellbore service treatment; a conveyance connected to the downhole tool for moving the downhole tool in the wellbore, and a plurality of sensors operable to provide one or more wellbore indications and attached to the downhole tool or a component thereof via one or more tethers. A method of monitoring a wellbore service treatment, comprising conveying into a wellbore a downhole tool operable to perform the wellbore service treatment and a plurality of sensors operable to provide one or more wellbore indications attached to the downhole tool or a component thereof via one or more tethers, deploying the downhole tool at a first position in the wellbore for service, treating the wellbore at the first position; and monitoring an at least one wellbore indication provided by the wellbore sensors at the first position.

Abstract: In a method for drilling, completing and fracturing a subterranean formation, an electrical potential is applied to oil or synthetic based drilling fluid to increase the viscosity of the fluid and enable the fluid to entrain drill cuttings and proppant. The same base fluid may be used for drilling, completion and fracturing by adjusting the electrical potential and consequently the viscosity of the fluid for the particular application. In fracturing, little or no potential is applied until the fluid enters the zone of the formation to be fractured. High potential is then applied at the fracture point of the formation to effect fracturing and to enable the fluid to transport proppant into the fracture.

Abstract: A system and method for treating a fluid flowing in a pipe according to which an element is provided in the pipe that vibrates to produce acoustic energy. The strength and frequency of the acoustic energy are such that the viscosity of the fluid is reduced.

Abstract: The present invention is directed to a method for producing gas from a subterranean formation containing a coal seam. The method includes the steps of drilling a substantially vertical well bore into the subterranean formation, which intersects the coal seam and fracturing the coal seam using a hydrajetting tool to produce at least one pair of opposed bi-wing fractures substantially along a plane of maximum stress. One or more horizontal well bores may also be drilled into the coal seam along which the coal seam can be further fractured.

Abstract: The present invention relates generally to methods for designing and optimizing the number, placement, and size of fractures in a subterranean formation and more particularly to methods that account for stress interference from other fractures when designing and optimizing the number, placement, and size of fractures in the subterranean formation. The present invention optimizes the number, placement and size of fractures in a subterranean formation. The present invention determinines one or more geomechanical stresses induced by each fracture based on the dimensions and location of each fracture.

Abstract: A system and method for removing scale from a device for supporting a gravel pack in a wellbore and for stimulating a formation penetrated by the wellbore, according to which a transducer and a driver for the transducer are mounted on a tool which is lowered into the wellbore in the vicinity of the device. The driver is actuated to vibrate the transducer to remove the scale and stimulate the formation.

High potential is then applied at the fracture point of the formation to effect fracturing and to enable the fluid to transport proppant into the fracture.

Abstract: A method is described for using an electro-rheological fluid as a drilling and completion fluid or as a well service or fracturing fluid. By adjusting the viscosity of the fluid through application of an electrical potential to the fluid, the fluid has enhanced flexibility and multiplicity of purpose over prior art fluids.

Abstract: The invention provides methods for combining well test analysis with wavelet analysis wherein the use of wavelet analysis with conventionally acquired well data provides verification of the well data. The methods include the steps of acquiring downhole data, converting the data to a first electronic signal, performing wavelet analysis of the first electronic signal to produce a second electronic signal, and using the second electronic signal to aid in the interpretation of the first electronic signal and/or to instigate corrective steps to ensure that the desired parameters of the well environment are accurately represented by the first electronic signal. Some or all of the steps may be performed in real-time.
