ABSTRACT: 2010 ASME/ALRDC/API/ISO Gas-Lift Workshop SPE Production Operations Engineering—Volume 4 Editor & Author: Joe Dunn Clegg The 2006 version of SPE’s Petroleum Engineering Handbook, Volume IV--Production Operations engineering, replaces the variousVolume IV Production Operations engineering, replaces the various chapters on production engineering in the 1987 edition. This rather long effort is the result of various distinguish authors, editors and the SPE. There have been many changes in technology and operating practices in the past twenty years and these new chapters will bring you up-to-date in design, selection of equipment and operation procedures for most oil and gas wellsfor most oil and gas wells. There are 16 chapters in this Production Operations Engineering (VOL.4) that are divided into three major groups: (a) well completions; (b) formation damage and stimulation; and (c) artificial lift. The initial chapters are mainly concerned with well completions. Chapter 1 is“Inflow and Outflow Performance.” This chapter is followed byCompletion Systems, Tubing Selection, Perforating and Sand Control.The next four chapters have to do with the formation damage problems: Formation Damage, Matrix acidizing, Hydraulic Fracturing, Problems . There are seven chapters that deal with artificial lift: Systems, Sucker p y ,Rods, Gas-Lift, ESP, Hydraulic, Progressive Cavity, & Plungers – all a major concerns for production operations engineers. Chapter 12, “Gas Lift” by Jack Blann and Herald Winkler discusses in detail bothcontinuous and intermittent gas lift. Closely related subjects may be found in the other volumes of the PEH and specific data found on equipment in the API Specifications and Recommended Practices(2) orequipment in the API Specifications and Recommended Practices or the International Organization for Standards (ISO) documents. Manyof these chapters are interrelated and references are made to other chapters. In general the necessary graphs, tables, and figures areincluded to make the design, but specific manufacturer data may have to be obtained from the vendors. Computer programs for design are

t i l d d b t i t l bl i d i dnot included, but in most cases example problems in design are covered. Joe Dunn Clegg Houston, October 18, 2009—I am now 82 years old and I started on thisproject when I was only 25.

Background for SPE Petroleum Engineering Handbook

2000: General consensus that the Bradley version of the PEH needed to be updated--(which was a revision of the previous Frick PEH).Review committee suggested that the BradleyReview committee suggested that the Bradley chapters needed to be revised. Suggest changes from no revisions, minor revisions minor updating major rewriting to addrevisions, minor updating, major rewriting to add or delete chapters. Original there were no drilling chapters. Larry W. Lake selected as chief editor. Section editors picked. Kick-off meeting for editors in August 2000. Selected chapters and pickedAugust 2000. Selected chapters and picked chapter authors. Not easy!First letters to PEH authors sent in Jan 2001.Suggested an outline deadline for each chapterSuggested an outline deadline for each chapter by August 2001.Lots of editing for 5 years! #Completed: Early 2008
