Some Rock-Mechanical Aspects of Oil and Gas Well Completions

Society of Petroleum Engineers Journal, 1985
Abstract Elementary borehole- and perforation-stability problems in friable clastic formations for unrestricted fluid flow between reservoir rock and underground opening are treated on the basis of linear poroelastic theory. Thermal stress effects caused by a temperature difference between reservoir and borehole fluids can be predicted ...

Concentric Completions of Oil and Gas Wells

Journal of Petroleum Technology, 1959
Introduction This paper discusses the use of 1 ¼-in. tubing placed concentrically inside the normal flow string in both oil and gas wells. The use of this extra string provides an annular space which can be employed to perform a number of functions. The Union Oil Co.

Intelligent Completion for Oil and Gas Production Control in Subsea Multi-lateral Well Applications

Proceedings of SPE Annual Technical Conference and Exhibition, 1996
Abstract This paper describes a permanently installed, electronically enhanced, downhole completion system for real-time communication, command, and control of oil and gas production in extended reach, multilateral and subsea wells.

Analysis of Skins and the Performance of Gravel-Packed Completions in Oil and Gas Wells

SPE Formation Damage Control Symposium, 1992
Abstract This paper presents solutions and analysis of mathematical model of skins due to completions in gravel packed oil and gas wells. The models can be divided into three cases: (1) Open Hole gravel packed well (2) Cased-hole perforated gravel packed well (3) Collapsed perforation tunnel gravel packed well.

Evaluation of Well Performance for the Slot-Drill Completion in Low- and Ultralow-Permeability Oil and Gas Reservoirs

SPE Journal, 2013
Summary Low- to ultralow-permeability formations require “special” treatments/stimulation to make them produce economical quantities of hydrocarbon, and at the moment, multistage hydraulic fracturing (MSHF) is the most commonly used stimulation method for enhancing the exploitation of these reservoirs.

Well Completion System Appraisal and Decision in Oil and Gas Reservoirs

Petroleum Science and Technology, 2011
Abstract To make completion selection mathematically, a comprehensive well completion system evaluation system was established including 3-class, 14-indicator including technical, managerial, economic, and risk indicators. Mutation theory was first introduced to determine the weights.
