The Marcellus play has been drilled and completed for many years and this congress isn't aiming to recall what operators already know. Liquid Rich Horizontal Completions Optimization: Marcellus & Utica 2014 is focused entirely on exploiting remaining high value, liquid rich opportunities that lie within the play in light of gas prices, and optimizing increasing opportunities in the Utica.
OPTIMIZING NPV IN LIQUID RICH MARCELLUS WELLS
The current gas price situation in the US however, means Marcellus operators need to be ahead of the game by developing highly advanced techniques for making marginal wells economic and developing completions strategies for optimizing liquid recovery. Operators are now actively making progress in reducing cluster spacing and optimizing stage and lateral lengths in liquid rich reservoirs to ensure incremental cost and performance gains. Due to the increasing number of trials measuring changes in such variables, the industry at large is now at a point where findings and information sharing could lead to significant commercial gains.
MAXIMIZING SRV AND WELL ECONOMICS IN HIGH PRESSURED UTICA WELLS
The liquid rich Utica is arguably an easy win for Marcellus operators and many are already seeing significant production successes due to the delivery of optimal completions techniques. However, the increase in near wellbore stimulation and lateral lengths, in the dense, typically higher-pressured, Utica wells, present their own cost challenges. These include ensuring the availability and development of higher PSI rated equipment, developing extended lateral completions strategies and creating frac designs suitable for high pressure wells; challenges that are often easily overcome by hearing what others have already failed and succeeded at.
A CONGRESS DEDICATED TO IDENTIFYING WHICH COMPLETIONS TECHNIQUES AND DESIGNS ARE DELIVERING THE GREATEST NPV IN LIQUID RICH MARCELLUS AND UTICA WELLS
The primary mission of the Liquid Rich Horizontal Completions Optimization: Marcellus & Utica 2014 congress is to determine which advanced completion techniques are being used by leading operators to improve well economics in the Appalachian Basin. Over two days, leading completions managers and experts from E&P companies will be delivering data driven strategies to optimize overall recovery by identifying which well design and frac design parameters are contributing most to production in liquid rich, marginal and high pressured wells in the Marcellus and Utica.
Case studies delivered over the two days include operator strategies for cluster spacing reduction, stage length and lateral length optimization, pump rate and proppant concentration decision making and perforation techniques to optimize completions design to maximize SRV and decrease operational costs in the Marcellus and Utica.

PetroSync - Chemically Enhanced Water Alternating GasPetroSync
It is know that two-third of the original oil in place are still in the ground. Petroleum companies are looking for techniques to improve sweep efficiency and increase recovery factors. As a result, Enhanced Oil Recovery (EOR) processes need to be carried out. Successful WAG floods can yield 5-20% additional oil recovery over waterflood because of improved microscopic displacement efficiency by the solvent coupled with improving areal and vertical sweep efficiency.

Bakken Artificial Lift & Production Optimization Congress 2014 marketinglbcg
The Bakken success story has continued into 2014, with the latest data showing that wells in the region are now producing over a million barrels of oil per day. However, operators are increasingly aware that with the productivity rate of Bakken wells shown to decline by an average of 70% in the first year, it is vital that they optimize the production phase of their operations if this explosive growth is to be sustained.
Operators in the region therefore increasingly need to know which artificial lift techniques and chemical treatments are working best in the Bakken to cost-effectively maximize production rates.
Building on the sell-out success of the first event in the series, the 2nd Annual Bakken Artificial Lift & Production Optimization Congress 2014 will again bring together Bakken's leading E&Ps for the only dedicated congress for production professionals in the Bakken, focusing on artificial lift, chemical treatments & production optimization.
Featuring a totally revamped agenda for 2014, the event this year will present 20+ brand new case studies based on work done in the last year. Speakers will be examining technical solutions for reducing failure rates, maximizing productivity & improving run times by optimizing artificial lift design & chemical treatments for Bakken wells & overcoming challenges relating to sand control, gas interference & wellbore deviation.
