  • Patent number: 9725987
    Abstract: A method of performing a stimulation operation for a subterranean formation penetrated by a wellbore is provided. The method involves collecting pressure measurements of an isolated interval of the wellbore during injection of an injection fluid therein, generating a fracture closure from the pressure measurements, generating transmissibility based on the fracture closure and a mini fall off test of the isolated interval during the injection, obtaining fracture geometry from images of the subterranean formation about the isolated interval, and generating system permeability from the transmissibility and the fracture geometry. The method may also involve deploying a wireline stimulation tool into the wellbore, isolating an interval of the wellbore and injecting fluid into the interval with the wireline stimulation tool. The fracture geometry may be obtained by imaging the formation, and fracture geometry may be obtained from core sampling.

  • Patent number: 9150138
    Abstract: A technique is provided to limit the number of vehicles required during a well project involving a plurality of well construction related procedures. The technique utilizes a modular unit, e.g. a vehicle, and a plurality of modules that may be interchanged on the modular unit according to the scheduled well procedure. A separate crane unit can be used to move the modules to and from the vehicle as required for specific phases of well construction.
