... in the Mediterranean (Abu Qir Field). In many mature gas fields, reservoir pressure decline as a result of gas depletion tends to lead to the onset of liquid loading. Liquid loading in gas wells occur when the gas flow rate falls below a critical rate due to reservoir depletion where the accompanying liquids cannot...

... of CRA (temperature, partial pressure of H 2 S and CO 2 , pH environment, chloride concentrations), it was decided to specify the use of 28 Cr CRA material for these Jurassic gas wells. This paper will discuss the initial study of the material metallurgy, the well design, the specification of tubulars...

... Abstract Usually four-point backpressure test, an isochronal test or a modified isochronal test is conducted to predict gas well deliverability. During past decades several simple dimensionless inflow performance relationships (IPRs) have been developed to eliminate the need for conducting...

... and struggling wellbores. More recently, Devon has focused its efforts on the use of Hydraulic Pumping Units (HPU), which have recorded an amazing track record in deliquifying and returning to production low-rate gas wells that no longer respond to plungers, soap or velocity strings. This paper examines Devon's...

... for optimizing well performance and maximizing gas recovery. The present work discussed determination of the rate profile from the pressure and temperature profiles in gas wells, which is significantly cheaper and more precise than the direct flow metering. An effective and robust algorithm for calculation...

... Abstract This paper presents a general and a simplified method for deliverability calculations of gas wells, which among other advantages, eliminates the need for conventional multipoint tests. The analytical solution to the diffusivity equation for real gas flow under stabilized or pseudo...
