Title: Method and apparatus for guiding a rod to a slitter station
Inventor: PONG DAVID TENG
IPC: B21B1/18
Filed: 1992-08-10
Granted: 2000-03-02
Abstract: A method and apparatus (15,16) for accurately slitting a rod (10) into two equal sections (10') in which the rod is longitudinally advanced to a slitter and is laterally shifted by an in-line guide adjustment system (20) or 1GA so that the slit sections will be equal. The rod sections are measured by the 1GA (21) after slitting to evaluate any difference in size therebetween while the sections are advancing, and the 1GA transversely shifts the rod before it enters the slitter to eliminate any size differential between the slit sections. The sizes of the sections are measured by measuring the size of loops (19) formed by the sections when they leave the slitter. The method and apparatus are especially applicable to a system in which the rod is advanced at relatively high speed through the roll stands (17,18) without twisting the rod between the stands or before and after the slitter. Also, the slit rod sections are advanced along separate lines in which the rod sections pass through roll stands without twisting. <IMAGE>

Title: Method of Modelling a Subsurface Volume
Inventor: ABADPOUR ANAHITA
Filed: 2015-08-13
Abstract: Disclosed is a method monitoring changes in saturation of a subsurface volume. The method comprises: ‎obtaining observed data of saturation behaviour from the subsurface volume over time; using one or ‎more models, obtaining simulated data of saturation behaviour from the subsurface volume over time; ‎and transforming each of the observed data and simulated data. The transformation is done such that in ‎each case the data is described in terms of: a front location parameter, wherein a cell of the subsurface ‎volume is attributed a value according to its location relative to a front of the fluid for which saturation is ‎being monitored, and a sweep intensity parameter, wherein a cell of the subsurface volume is attributed a ‎value according to either the observed saturation variation over a time period, or an estimated saturation ‎variation over the time period. finally, a mismatch between saturation behaviour in said transformed ‎observed data and saturation behaviour in said transfo

Title: Buffered friction reducer for subterranean operations
Inventor: LORD PAUL
Filed: 2019-01-03
Abstract: Systems and methods having friction reducer compositions for use in subterranean treatment fluids are provided. An embodiment of the present disclosure is a method comprising: (A) forming a treatment fluid comprising: an aqueous base fluid, a friction reducer, and an alkaline buffering agent, wherein the treatment fluid has a pH in the range of about 7 to about 10; and (B) injecting the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation at a pressure sufficient to create or enhance one or more fractures within the subterranean formation.
