This workbook is a practical companion to the second edition of the textbook Reservoir Stimulation. The two books are intended to be used together. This new volume should be particularly useful for the training of new engineers and petroleum engineering students, as it contains approximately 100 problems and their solutions, plus a lengthy chapter giving data necessary for designing a stimulation treatment. Chapters are included containing practical problems on reservoir and well considerations, rock mechanics, fracturing fluids and proppants, fracture calibration treatments, design and modeling of propped fractures, evaluation of fracture treatments, design of matrix treatments, diversion and treatment evaluation, design and performance of acid fractures and stimulation of horizontal wells. These chapters are labeled with letters from A to J to distinguish them from their companion chapters in Reservoir Stimulation. Equations, figures and tables from the textbook are referred to in the workbook but are not reproduced.
