...-storage durations. This technique can obtain well and reservoir information faster than a conventional PBU test. One issue with unconventional wells, particularly tight gas wells, is that the wellbore storage lasts significantly longer than in standard wells. A downhole shut-in tool or any test...

..., is reached. Higher values of the limiting saturation leads to a greater reduction in permeability and hence results in a larger skin value for the gas well. The flow efficiency of a gas well, calculated as a dimensionless ratio of the flow with and without skin, decreases continually and asymptotically...

... The equation for pressure distribution in the horizontal wellbore can be expressed as: Abstract It has been recognized that horizontal-wellbore friction significantly affects deliverability of gas wells in highly productive reservoirs. But there is lack of a simple and rigorous flow model...

... is acquiring an acoustic fluid level by "shooting" the well down the tubing. The results from this type of test on a gas well can be used to determine 1) the amount of liquid and backpressure on the formation, 2) the gas rate into tubing, 3) the equivalent fluid gradient below the liquid level, and 4...

... ensures the filter medium is undamaged when running the screens in hole. It also ensures that the filter media remain tightly packed together after expansion 8 . ESS does not have much historical performance record in high rate gas wells here. Other jobs with ESS in oil wells have been simple...

... Abstract Improvements to pressure traverse (predictions) using simple modifications to a two phase flow program (Gray 1 , 2 correlation) for gas wells producing some liquids have been discussed in this paper. The Gray correlation was found to be the best of several initially tested...

... to non-Darcy effects, the measured proppant permeability values fail to incorporate the effects of multiphase flow. Most gas wells will produce some free liquid (water or condensate), and almost all oil wells will be produced below the bubblepoint of the oil, resulting in substantial volumes of free gas...

...-in. tubing was large enough to produce from normal oil and gas wells. Early Slim-hole technology, however, failed to gain widespread acceptance in the industry. Not only was much of the equipment inadequate or unproven, but increasing oil prices and low production cost made any cost savings seem unimportant...
