The ability of this reservoir to deliver a certain quantity of ga s depends both on the inflow performance relationship and the flowing-bottom-hole pressure. The flowing bottom-hole pressure on its part depends on the separator pressure and the configuration of the piping system. In order to determine the deliverability of the total well system , it is necessary to calculate all the parameters and pressure drop s. Static and flowing.
Bottom Hole Pressure Relationship - Drilling Formulas and Drilling Calculations
Production Data Diagnostics. Single-Phase Flow in the Reservoir. Case Studies. The analysis of production data to determine reservoir characteristics, completion effectiveness and hydrocarbons-in-place is becoming more and more prevalent.
DETERMINING THE STATIC AND FLOWING PRESSURES OF A GAS WELL
Arabian Journal for Science and Engineering. The SBHP is normally acquired through gauge measurements; however, this method has disadvantages such as cost and risk. Accordingly, the ability to accurately estimate the SBHP would provide a cost-effective and safe alternative to well intervention.
Gas behaves differently from fluid therefore you cannot use a simple hydrostatic formula to determine reservoir pressure. Gas is compressible but fluid is incompressible. Example: The dry gas well is shut in and the well head pressure is 2, psig gauge pressure.
