The 22-in. vertical section was selected because it was determined to be the most challenging section. The following key observations were made during the drilling run when the circulation was lost...

..., and pressures. Parent-Well Surface Pressure. Parent-well surface pressure data can be important for FH analysis. Such data provide direct measurement of the timing and magnitude of FHs at the parent well. FH-event timing typically can be correlated with the pumping of a specific completion stage when integrated...

... ) was constrained using leakoff tests (LOTs) and mini- and microfracturing data. No rock-mechanical testing data were available, and rock properties were estimated from petrophysical logs using regional experience. Magnitude and orientation of maximum horizontal stress ( Sh max ) was constrained using the presence...

Typically, these tools consisted of one hydrophone or receiver that was limited to frequency and information recorded. The majority of these tools...

... that the magnitude of the pressure drop in the wellbore is negligible. Practically speaking, however, production data proved otherwise; frictional pressure losses in horizontal wellbores hinder flow influx to different degrees along the horizontal section. This issue is of great importance under conditions in which...

..., the human activity would need to pour energy into what is known as an active fault. This is a fault which, when energized, will cause Earth movement. According to the US Geological Survey, the magnitude of an earthquake will be directly proportional to the length of the active fault. Faults can be detected...

... are usually lower than those of the vertical stress. The horizontal-stress magnitudes, however, may exceed those of the vertical stress in strongly tectonic regions. A stress state can be defined as normal-fault, reverse-fault, or strike/slip-fault state of stress. The normal-fault stress state is assumed...

This study characterized the magnitude of these SP signals to determine if their measurement, using permanently installed downhole electrodes, might...

.... Drilling optimization can be achieved by preselecting the magnitudes of the controllable drilling parameters. Most of the early studies described in the literature have foreseen a static drilling-optimization process. In the past, drilling parameters were required to be investigated off site because...

Perhaps the greatest benefit attributable to petroleum has been its extraordinary ability to meet a century and a half...

.... The hypocenter is defined as the location of the origin of the seismic deformation associated with the microseism. To quantify the deformation that occurs during the microseism, a measure of the strength of the microseism is required. The strength or size of any seismic event is usually reported as a magnitude...
