Utility
Hydraulic fracturing method using non-standard proppant
9 Mar 21
The present disclosure provides a method for hydraulic fracturing of a formation penetrated by a wellbore, the method comprising: providing a proppant and a two-component adhesive; injecting a proppant-free fracturing fluid into the wellbore to form a fracture in the formation; pulse-injecting the fracturing fluid into the wellbore, wherein pulse-injection provides for at least one injection pulse of the proppant-laden fracturing fluid comprising the two-component adhesive and at least one injection pulse of the proppant-free fracturing fluid, wherein the proppant is characterized by at least one of the following properties: the resistance of the proppant to crushing is lower than the rock closure pressure; when a pressure of 20.7 MPa is applied to this proppant, at least 5 wt. % of particles with a size of less than 100 μm are formed; the size distribution of the proppant is 10-1,000 μm; the sphericity and/or roundness of the proppant is less than 0.6; the solubility of the proppant in acids is 5-20 wt. %; providing an initiation mechanism to induce the adhesion of proppant particles to form bonded clusters that prevent the fracture from closing and form network channels open for the flow of fluids.

Method for Removing the Effect of Near Surface Galvanic Distortion In Surface to Borehole Em Measurements
4 Mar 21
A system and method of evaluating and correcting for the effects of a near-surface anomaly on surface-to-borehole (STB) measurement data in a geological halfspace comprises transmitting electromagnetic radiation from an EM source located on a ground surface which is positioned over the near-surface anomaly, measuring EM fields at a plurality of remote EM receivers located on the surface at a far distance from the EM source, obtaining vertical STB measurement data downhole, determining an orientation and moment of a secondary source equivalent dipole associated with the near-surface anomaly excited by the radiation transmitted by the EM source based on measurements of the EM fields at the plurality of remote receivers, determining a correction factor for the secondary source equivalent dipole on the EM field measurements at the plurality of remote receivers, and removing the effects of the near surface anomaly on the vertical STB measurement data using the correction factor.
