Available in PDF, EPUB and Kindle. Book excerpt: In this new second edition, author Leonard Kalfayan has updated his 2001 book on acid stimulation, one of the primary methods for improving productivity of oil, gas, injection, and disposal wells. A properly designed and executed acid job can improve cash flow. Kalfayan offers practical guidelines for acid treatment design by stressing a systematic approach to candidate selection, treatment design, as well as execution and evaluation for improvement in profits and productivity. The new edition includes discussions of modern acid systems and treatment methods with worldwide applications for both carbonate and sandstone formations; new concepts for simplifying and proliferating sandstone acid application; the latest in carbonate matrix and fracture acidizing; more on non-conventional acidizing concepts and acid systems; and more on geothermal well stimulation. As with his original book, readers can find practical, useful acidizing information and gain greater understanding and appreciate of its benefits.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrochloric acid stimulation was successfully used on several wells in the Los Angeles Downtown Field, in the past. The decline rates after stimulation were relatively high and generally within six months to a year, production rates have returned to their prestimulation rates. The wells in Los Angeles Downtown Field have strong scale producing tendencies and many wells are treated for scale control. Four wells were carefully selected that are representative of wells that had a tendency to form calcium carbonate scale and had shown substantial decline over the last few years.

Available in PDF, EPUB and Kindle. Book excerpt: Good engineers never stop looking for opportunities to improve the performance of their production systems. Performance enhancement methods are always carefully examined, and production data is analyzed in order to identify determining factors affecting performance.The two main activities of the production engineer in the petroleum and related industries are reservoir stimulation and artificial lift. The classic solution to maximizing a well's productivity is to stimulate it. The basis for selecting stimulation candidates should be a review of the well's actual and theoretical IPR. Low permeability wells often need fracturing on initial completion. In low permeability zones, additional post stimulation production can be significant to the economics, however, the production engineer needs to make management aware of the true long term potential or else overly optimistic projections can easily be made.The main purpose of stimulation is to enhance the property value by the faster delivery of the petroleum fluid and/or to increase ultimate economic recovery. The aim of reservoir stimulation is to bypass near-wellbore damage and return a well to its “natural” productivity / injectivity, to extend a conductive path deep into a formation and thus increase productivity beyond the natural level and to produce hydrocarbon from tight formation.The importance of reservoir stimulation is increasing due to following reasons: • Hydrocarbon fields in their mid-life• Production in these fields are in declining trend• The thrust area: Enhancement of productionHence, to improve productivity of the well matrix stimulation and hydraulic fracturing are intended to remedy, or even improve, the natural connection of the wellbore with the reservoir, which could delay the need for artificial lift.This book presents procedures taken in the Oil & Gas Industry for identifying well problems, and it suggests means of solving problems with the help of the Coil Tube unit which is used for improving well productivity and techniques like Acidizing and Hydraulic Fracturing.

Available in PDF, EPUB and Kindle. Book excerpt: To increase the successful rate of acid stimulation, a method is required to diagnose the effectiveness of stimulation which will help us to improve stimulation design and decide whether future action, such as diversion, is needed. For this purpose, it is important to know how much acid enters each layer in a multilayer carbonate formation and if the low-permeability layer is treated well. This work develops a numerical model to determine the temperature behavior for both injection and flow-back situations. An important phenomenon in this process is the heat generated by reaction, affecting the temperature behavior significantly. The result of the thermal model showed significant temperature effects caused by reaction, providing a mechanism to quantitatively determine the acid flow profile. Based on this mechanism, a further inverse model can be developed to determine the acid distribution in each layer.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlocking a tight carbonate formation for oil and gas production by multi-stage acid stimulation is a relatively cost-effective method as an alternative to propped fracturing for production enhancement. Depending on whether treatment pressure is below or above the formation closure stress, acid stimulation is basically divided into matrix acidizing and acid fracturing. In this study, practical methodology to evaluate both matrix acidizing and acid fracturing through treatment monitoring is presented respectively. For matrix acidizing, monitoring and optimizing a matrix acidizing has been achieved by integrating a forward model used in acidizing design for horizontal wells with a real-time monitoring model for skin evolution during the stimulation. The effect of acidizing is described as an overall skin factor change, and productivity improvement is predicted for the treatment. Then the field treatment data monitored on-site was used to estimate the skin response by treatment injection. History matching procedure of design and actual treatment data will be carried out to update near-wellbore and key wormholing parameters. Through sensitivity study, which parameter should be updated is discussed. Finally optimum rate schedule is identified based on updated parameters. Meanwhile, for acid fracturing treatment, new method for real-time monitoring of acid fracturing, the inverse injectivity vs. superposition time function plot is proposed, subject to the condition that the treatment pressure is above closure pressure after the breakdown. Combining a linear dual-porosity transient slab model with injectivity concept, actual growing cross-sectional area induced by acid fracturing treatment can be monitored in real-time. After production starts, linear flow diagnostic approach with rate-transient analysis provides cross-sectional area flowing from matrix, which is compared with the area induced by acid fracturing during the stimulation. The treatment efficiency provides engineers with additional information as to whether the designed acid fracturing was performed appropriately under the in-situ closure stress field. A field case example of both multi-stage matrix acidizing and acid fracturing acid in horizontal well are also presented respectively in the study to illustrate the application of the approach developed, and to show the value of the integrated approach to monitor and diagnose acid stimulation in horizontal wells.
