Abstract:
In one aspect, a production system is disclosed that in one embodiment may include a production tubing placed inside the wellbore, an ESP in the wellbore for flowing fluid from the wellbore into the production tubing, a sensor string including distributed sensors along the sensor string that provides temperature measurements along the production tubing uphole of the ESP, and a controller that determines from the temperature measurements a change in temperature that exceeds a threshold and determines therefrom level of a liquid in the wellbore.
Abstract:
The present invention provides a pattern formation method capable of preventing formation of surface defects. In the method, a resist surface after subjected to exposure is coated with an acidic film and then subjected to heating treatment. This method is suitably adopted in a process employing liquid immersion lithography and/or light of short wavelength, such as ArF excimer laser beams, for producing a very fine pattern.
Abstract:
The disclosure discloses a method for switching e-mail accounts on a mobile terminal and the mobile terminal. The following steps are involved in a solution of the disclosure: setting the information of multiple mail accounts on the mobile terminal; editing an e-mail under a first mail account which is currently activated and selecting a mail account for sending; when determining that the selected mail account for sending is the first mail account, performing the sending process directly; when determining that the selected mail account for sending is not the first mail account, switching the mail account for sending to a second mail account, saving the currently edited e-mail to the second mail account, and performing the sending process. The disclosure implements the function that the mail is edited under one of the mail accounts and sent under another already-configured mail account when there are multiple mail accounts. Furthermore, the mail account which is currently activated is switched only at the sending stage, and it is re-switched back to the previous mail account after the completion of the sending. Then system resources are saved.
Abstract:
A method and apparatus for estimating a pressure transition zone in a borehole is disclosed. A parameter indicative of formation fluid pressure at a plurality of borehole depths is measured. A global trend of the parameter is determined over a first depth interval and a local trend of the parameter is determined over a second depth interval. A relation is determined between the global trend and the local trend, and the pressure transition zone is determined from the determined relation between the determined global trend and the determined local trend.
Abstract:
A system for measuring a fluid flow rate in a wellbore disposed in an earth formation is disclosed. The system includes: a wellbore assembly configured to be disposed along a length of a wellbore, the wellbore configured to receive a wellbore fluid therein; a distributed temperature sensor (DTS) assembly disposed along the length of the wellbore and configured to take a plurality of temperature measurements along the length of the wellbore; and a processor in operable communication with the fiber optic sensor, the processor configured to receive the temperature measurements and apply a fluid flow rate model of fluid flow rates to the temperature measurements to calculate a fluid flow profile of the wellbore. The model is based on a steady-state energy balance between the wellbore fluid and the earth formation and a Joule-Thomson coefficient including a liquid volume expansion factor and a fraction of gas in the wellbore fluid.
Abstract:
A method of evaluating a stimulation operation includes: receiving parameter information for the stimulation operation, the stimulation operation including injecting an acid stimulation fluid into an earth formation along a selected length of a borehole from a tubular disposed in the borehole; and generating, by a processor, a thermal model based on one or more energy balance equations that account for at least a first heat source and a second heat source, the first heat source expected to produce heat during the stimulation by a chemical reaction between an acid in the stimulation fluid and the formation, and the second heat source including expected geothermal heat from the formation.

The apparatus includes: an electricity meter module, configured to detect battery power consumption parameters under driving of a data acquisition module; the data acquisition module, configured to drive the detection of the electricity meter module, and output the collected battery power consumption parameters to a data analysis module; the data analysis module, configured to estimate power consumptions of all running devices at present in the terminal according to the input battery power consumption parameters, and output a power consumption optimization instruction to a power consumption optimization execution module; and the power consumption optimization execution module, configured to adopt corresponding power consumption optimization approaches according to the input power consumption optimization instruction.
Abstract:
A completion system includes a first borehole structure having a first section formed proximate to a volume of methane hydrate located at a subsurface location. A second borehole structure has a second section formed proximate to the volume of methane hydrate, the first section positioned deeper than the second section with respect to gravity. A first string is positioned in the first borehole structure and arranged to convey a heat-bearing fluid through the first string into contact with a volume of methane hydrate in order to liberate methane from the methane hydrate. A second string is positioned in the second borehole structure and arranged to produce the methane.
