Multiphase Flow Properties Pressure Gradient Calculation
For oil wells, the main component of pressure loss is the gravity or hydrostatic term. Calculation of the hydrostatic pressure loss requires knowledge of the proportion of the pipe occupied…
Introduction to IPR and VLP
The productivity of the well depends on an efficient use of the compressional energy available in the reservoir allowing the reservoir fluids to flow toward the production separator. As an…

Isochronal tests for gas wells
The isochronal test is a series of single-point tests developed to estimate stabilized deliverability characteristics without actually flowing the well for the time required to achieve stabilized conditions at each different rate.…
Gas well deliverability
Early estimates of gas well performance were conducted by opening the well to the atmosphere and then measuring the flow rate. Such “open flow” practices were wasteful of gas, sometimes…

Petroleum Production Optimization
Fundamentals Production Optimization refers to the various activities of measuring, analyzing, modelling, prioritizing and implementing actions to enhance productivity of a field: reservoir/well/surface . Production Optimization is a fundamental practice to…
Intelligent wells
The generic term “intelligent well” is used to signify that some degree of direct monitoring and/or remote control equipment is installed within the well completion. An intelligent well has the…
Well Head Installation Video
Wellhead installation is one of most fascinating topics and it is very difficult to visualize how this operation is performed. However, if you see this video, it will make the…
DOWNHOLE MATERIAL SELECTION SERVICES
Downhole materials selection is one on the most debated topics during the well design process. A material selection that is too conservative can add substantial initial cost of the equipment.…
