The test can be performed without breaking the fuel line and with a minimal number of hardware components, including a communication cable, a pressure transducer, a power source, an electronic computer and video display terminal. The system for performing the test includes a processor for giving ...
However, none of them give the characteristics of pressure buildup test for such wells. In recent years, the impact of fracture (artificially-induced or natural fracture) permeability loss on production performance of shale gas wells has drawn much attention. Some researchers (e.g. Ozkan et al...
The best way to efficiently clean outdoor surfaces is with a pressure washer, a blaster that uses less water to do its work than a garden hose and nozzle.
The gas then goes through the test chamber and is compressed by the diffuser before reaching the vacuum tank. Each element of the facility is described in details here. 4.5.6.2.1 The Air Heater The air upstream of the nozzle is heated to a stagnation temperature Tst by a Joule effect ...
1. Suitable for oilfield pressure test, line sweeping, gas lift, well drilling and other projects. 2. Used in air tightness testing, air tightness inspection, pressure test, strength inspection, air tightness verification and other fields of various high-pressure vess...
In order to find out whether the response of luminescence is towards the special gas molecule N2 or towards normal gas pressure, different kinds of gas molecules were applied to the above luminescence response test. Besides N2, we inflated the other three kinds of gas molecules (carbon dioxide,...
NSPAS3 is compatible with the pressure test range of 10kPa~400kPa and can detect refrigerant leakage pressure. The standby power consumption of this product is less than 3mA, and the response time is within 0.8ms. In addition, the chip package is coated with anti-corrosion jelly glue, whic...
(4) Use environment that is not suitable for equipment operation. Such as high temperature, humidity, corrosive gas or vibration. (5) Problems caused by movement or transportation. (6) Consumable components. (7) Natural disasters 3. What is...
Assuming negligible pressure loss in the surface injection line, determine the minimum required gas injection pressure using a kinetic energy index safety factor of 1.2 for the design gas injection rate. 2. Plot profiles of the pressure, velocity, gas density, and kinetic energy index along the ...
Despite giving the best precision in the training step, the RBF model exhibits fairly great deviations for the test data points with an AARE of 21.04%. Consequently, this model cannot be assumed as a capable predictive tool. Overall, although all newly proposed models perform much better than ...
