Available in PDF, EPUB and Kindle. Book excerpt: Horizontal wells are drilled to achieve improved reservoir coverage, high production rates, and to overcome water coning problems, etc. Many of these wells often produce at rates much below the expected production rates. Low productivity of horizontal wells is attributed to various factors such as drilling induced formation damage, high completion skins, and variable formation properties along the length of the wellbore as in the case of heterogeneous carbonate reservoirs. Matrix acidizing is used to overcome the formation damage by injecting the acid into the carbonate rock to improve well performance. Designing the matrix acidizing treatments for horizontal wells is a challenging task because of the complex process. The estimation of acid distribution along wellbore is required to analyze that the zones needing stimulation are receiving enough acid. It is even more important in cases where the reservoir properties are varying along the length of the wellbore. A model is developed in this study to simulate the placement of injected acid in a long horizontal well and to predict the subsequent effect of the acid in creating wormholes, overcoming damage effects, and stimulating productivity. The model tracks the interface between the acid and the completion fluid in the wellbore, models transient flow in the reservoir during acid injection, considers frictional effects in the tubulars, and predicts the depth of penetration of acid as a function of the acid volume and injection rate at all locations along the completion. A computer program is developed implementing the developed model. The program is used to simulate hypothetical examples of acid placement in a long horizontal section. A real field example of using the model to history match actual treatment data from a North Sea chalk well is demonstrated. The model will help to optimize acid stimulation in horizontal wells.

Available in PDF, EPUB and Kindle. Book excerpt: Well Productivity Handbook: Vertical, Fractured, Horizontal, Multilateral, Multi-fractured, and Radial-Fractured Wells, Second Edition delivers updated examples and solutions for oil and gas well management projects. Starting with the estimation of fluid and reservoir properties, the content then discusses the modeling of inflow performance in wells producing different types of fluids. In addition, it describes the principle of well productivity analysis to show how to predict productivity of wells with simple trajectories. Then advancing into more complex trajectories, this new edition demonstrates how to predict productivity for more challenging wells, such as multi-lateral, multi-fractured and radial-fractured. Rounding out with sample problems to solve and future references to pursue, this book continues to give reservoir and production engineers the tools needed to tackle the full spectrum of completion types.

Book excerpt: A number of activities have been carried out in the last three months. A list outlining these efforts is presented below. The Ph. D. Dissertation on developing correlations for breakthrough time and post breakthrough behavior of horizontal wells was successfully defended in March. A paper on this work will be presented in the Fifth SPE Latin American and Caribbean Conference to be held in Rio de Janeiro, Brazil in September. Multi-lateral wells offer higher productivity than single horizontal wells. However, the increase in their productivity depends on the length and form of the laterals. We have initiated a simulation study to investigate the productivity of multi-lateral wells in terms of their arrangement and positioning. The experimental work on using horizontal wells as injectors and producers in a gas injection gravity drainage process is progressing. Experimental setup is near completion and trial runs will follow next. Work on generalized gridding methods continued by considering streamline grids. In this approach, gridblock boundaries are aligned along streamlines to better rep- resent flow paths governed by heterogeneities. The correct well index for a typical partially penetrating horizontal well could be very different from the classical well index and can be calculated in a semi analytical fashion in which the well pressure is obtained analytically and the well block pressure is computed numerically. In the so called explicit well modeling approach, the need to calculate any well index is eliminated by fine gridding the well. We have studied this second approach and have shown that it can lead to incorrect results. The last activity listed above is the subject of this quarterly report.
