2001 ASME/API Gas-Lift Workshop Gas-Lift Future An Extension of the Past, or a Whole New World? by Cleon Dunham, Oilfield Automation Consulting John Martinez, Production Associates 2001 Fall ASME/API Gas-Lift Workshop
Gas-Lift Future • Outline • Is the past good enough? • What are some "bright lights?" • What can the future be? • The challenge 2001 Fall ASME/API Gas-Lift Workshop
Is the Past Good Enough? • The past has often been characterized by: • For the Operating Companies • Excessive use of gas • Excessive production deferment • Excessive CAPEX and OPEX • Poor application of gas-lift equipment in some cases • Many gas-lift experts have retired or left the company • High staff turn-over • Inadequate training programs and poorly trained staff • Inadequate focus on the surveillance process • Inadequate understanding of the problem and what to do about it 2001 Fall ASME/API Gas-Lift Workshop
Is the Past Good Enough? • For the Supply/Service Companies • Little incentive to improve gas-lift products • Little incentive to follow industry standards • Little incentive to invest in R&D • Limited competition • For the Universities • Few faculty trained to teach gas-lift • Few students interested in gas-lift • Limited funding for gas-lift programs, R&D 2001 Fall ASME/API Gas-Lift Workshop
Is the Past Good Enough? • For Others • Variety of different programs and approaches • Inconsistency among "consultants" advice 2001 Fall ASME/API Gas-Lift Workshop
What are some "Bright Lights?" • Some emerging "bright lights" • Gas-Lift Hardware • Equipment standards • Recommended practices • Valve improvements • Surface controlled gas-lift valves • Gas-Lift Processes • Surveillance improvements • Software improvements • Training developments • Integration with other forms of artificial lift 2001 Fall ASME/API Gas-Lift Workshop
What are some "Bright Lights?" • Information Sharing • Gas-lift workshops • Focus on artificial lift R&D 2001 Fall ASME/API Gas-Lift Workshop
What can the Future Be? • The future can be characterized by: • For the Operating Companies • Optimum use of injection gas • Optimum production, minimum unplanned deferment • Optimum investment --- CAPEX, OPEX • Effective selection and application of gas-lift equipment • Effective surveillance of all gas-lift wells, all of the time • Effective use of a well-defined surveillance process • Access to effective, on time, training and staff development • Clear choices --- optimum selection of artificial lift method(s) 2001 Fall ASME/API Gas-Lift Workshop
What can the Future Be? • The future can be characterized by: • For the Operating Companies • Use of high-pressure injection gas coupled with single point lift, which eliminates unloading valve problems • Implementation of excellent dehydration facilities to eliminate freezing and loss of production and to eliminate gas distribution piping corrosion • Use of various fluids for lift – nitrogen, CO2 – that can also be used for reservoir pressure maintenance • Early installation of gas lift system while wells have highest production rates - quicker payout • Promote high rate gas lift and reduce wells required for field development 2001 Fall ASME/API Gas-Lift Workshop
What can the Future Be? • For the Supply/Supply Companies • Stronger incentives to build high quality equipment • Higher rewards for high quality, innovative designs • Higher market share to those that build to industry standards • For the Universities • Renewed interest in gas-lift and artificial lift in general • Expanded sources of interested faculty and students • Better placement opportunities for qualified students • Expanded interest in R&D programs 2001 Fall ASME/API Gas-Lift Workshop
What can the Future Be? • For Others • Stronger demand for effective consulting, training 2001 Fall ASME/API Gas-Lift Workshop
The Challenge • How to move from the (undesirable) past to the (desired) future • By the Operating Companies • Gain a clear understanding of the economics of both "inaction" and "action" • Pro-actively seek to improve gas-lift operations, optimization, surveillance, training, etc. • By the Supply/Service Companies • Pro-actively work with Operating Companies to understand real needs and the value in meeting them • Aggressively develop required new capabilities 2001 Fall ASME/API Gas-Lift Workshop
The Challenge • By the Universities • Pro-actively develop enhanced gas-lift (and artificial lift) programs to attract high quality faculty and students • By Others • Aggressively communicate the "value proposition" that gas-lift can help create much more net value when it is properly understood, implemented, and applied 2001 Fall ASME/API Gas-Lift Workshop
