WebJul 1, 1991 · Merkulov 9 originally reported the expression for the ideal PI of a horizontal well in an isotropic reservoir. Giger 1 and Joshi 2 presented the pressure profile created by 3D steady-state flow to a horizontal well located inside an ellipsoidal drainage area (Fig. 1a).Their solution, which is suitable for horizontal wells that have small lengths compared … WebJun 25, 2015 · Hole-cleaning efficiency and solids transport are primarily controlled by liquid-phase velocities and solids concentration. Studies and field experience have shown that removal of cuttings is more efficient with two-phase fluid. The addition of a gas medium generates a turbulent flow regime, which minimizes solids bed formation.

Multirate tests can be conducted on both oil and gas wells. In these tests, several stabilized flow rates, qi , are achieved at corresponding stabilized flowing bottomhole pressures, pwf. The simplest analysis considers two different stabilized rates and pressures. The IPR can be written as ....................(1) … See more For many gas wells and some oil wells, flow rates are sufficiently high that turbulent or inertial pressure drops near the wellbore can be significant. In such cases, the additional … See more The most common method for determining skin is a pressure-buildup test. In this test, a well that has been producing for a time, tp, is shut in for time Δt. The pressure buildup is recorded … See more In gas wells in which it takes a long time to achieve stabilized rates, wells are shut in and produced for a fixed time interval (Δt) at several different rates. These isochronal tests are then interpreted by the following "deliverability" … See more Use this section to list papers in OnePetro that a reader who wants to learn more should definitely read See more WebOil removal efficiency at different gas flow rates is obtained by measuring the oil concentration at point A and point C. The impact of the gas flow rate on oil removal efficiency is illustrated in Figure 5. The corresponding experimental conditions are as follows: the oil droplet size is 30 μm, and the oil concentration at point A is 100 mg/L.
