September 2007 – New and Emerging Water and Gas Shut-off Techniques in Vertical and Horizontal Open Hole – Challenges and Opportunities
Unwanted water and gas production in producing wells negatively impacts the productive life of the wells and the reservoir itself. As more and more reservoirs are maturing, the urgency to develop methods to control unwanted fluid production, and thus to improve the recovery efficiency of the wells and the reservoirs is imperative. Many negative effects that occur during production such as high WOR and GOR, scaling, and skin damage can be pro-actively prevented during drilling by using new and emerging Conformance While Drilling (CWD) technology and thus can facilitate to shut off future water and gas influx.
This presentation will focus on the new and emerging solutions to the challenging conformance problems using processes, chemical systems, techniques, tools, and real time predictive methods and software to derive successful water and gas shut-off solutions for both vertical and horizontal wells. Water shut-off problems and solutions for more challenging open-hole horizontal completions using the emerging chemical and swell packer systems and placement techniques based on the reservoir understanding of the problems will be discussed. Critical factors for developing a successful conformance solution and a water management strategy will be identified. Real life field case histories in deriving successful conformance solutions will be presented.

January 2008 – Application of Low Viscosity Fluids to Hydraulic Fracturing
The use of low viscosity fluids for hydraulic fracturing has a history as long as hydraulic fracturing itself. In the last fifty years, as more viscous fluids gained in popularity the application of low viscosity fracturing fluids declined. Today, however, the application of low viscosity fracturing fluids, such as, treated water in hydraulic fracturing is seeing resurgence in the industry. This presentation will focus on Why this resurgence is occurring? Why use water as a fracturing fluid and why now?
In addition to answering these questions, the presentation will address the inherent risks of low viscosity fracturing fluids and identify guidelines for their successful application by outlining risk mitigating tests and treatment designs. These guidelines were developed through extensive theoretical and numerical research and tested via numerous field applications throughout the world.
Finally, this presentation will cite additional uses and benefits of thin fluids for both completion and reservoir engineering purposes. Such additional uses can play a significant role in the optimization, design, and field execution of a fracturing treatment to ensure maximum productivity and that the economic value of the resource is being maximized.

February 2008 – Naturally Occurring Gas Hydrates
Naturally occurring natural gas hydrates were first discovered in the 1960’s in Russia. Since that time, large deposits of gas hydrates have been found in the arctic regions of Russia, Canada and Alaska. However, most of the naturally occurring gas hydrates are located in the deep water basins around the world. These naturally occurring gas hydrates can be considered either as a hazard to drilling and conventional oil and gas production or as a vast potential energy source, depending upon your point of view. In the past few years, projects in Canada, Alaska, Japan, the Gulf of Mexico and offshore Oregon have provided new data that industry is using to assess these naturally occurring gas hydrate deposits. Some companies are using these data to address safety and environmental issues. Other companies are using the data to determine if these hydrate deposits can eventually be produced. In this presentation, I will provide data concerning the location and quantities of known gas hydrate deposits. I will review the recent data collection activities and research efforts. Finally, I will provide a view of if and when natural gas will be produced as an energy source.

March 2008 – Getting the Last Gasp: Deliquification of Challenging Gas Wells
A common characteristic of "challenging" unconventional gas resources, namely low permeability sands, shale and coal bed methane, is that the ultimate recovery is dependent on economic removal of liquids accumulation, generally termed "deliquification". This resource is making up an ever-increasing part of the North American gas supply. Since there is no one "perfect solution", and the problem affects thousands of wells, the opportunity involves not only technology development but also knowledge management and building resource capability.
This paper outlines the scope of impact and opportunity in North America, followed by the industry's approach and progress in the arena. The North American industry is working a variety of deliquification technologies for "challenging" gas, with developments ranging from adapting existing oil-field technologies, to developing gas-specific technologies, to "on the horizon" technologies. Examples in each stage of the development process will be shown.
The effective communication of these developments to operators and suppliers is also a necessary component. The industry-wide annual conferences that have emerged in the last seven years are the primary avenue for this communication, and are supplemented in some cases by operator internal networks.
This combination of technology development and effective communication is increasingly allowing North American operators to maximize the recovery of challenging gas resources.
Bryan Dotson is Deliquification Project Leader for BP in Houston. A chemical engineering graduate from the University of Oklahoma, he joined BP predecessor Amoco in 1980. He has worked primarily with surface facilities in onshore US, offshore Alaska, offshore Trinidad and in Bolivia.
May 2008 – The Importance of Ethics in Estimating Oil & Gas Reserves
Estimating oil and gas reserves is not a precise science. The ability, judgment, and experience of the estimator are very necessary for good and reliable estimates. However, it is also critical for the estimator to be honest and unbiased. Without these characteristics the reserve estimates are either misleading or outright wrong and can cause very large capital losses for companies and investors.
Overall, the oil and gas industry has a good record of properly estimating and reporting reserves. However, there are exceptions. Reserves are sometimes improperly estimated due to inability and lack of experience, bias or dishonesty, pressure from management, or a different interpretation than what is generally accepted of the role of ethics in the estimation process. Each of these reasons will be examined. Actual examples will be shown and discussed to illustrate the importance of ethics in the reserve estimating process. Finally, a guideline to proper ethics for estimating oil and gas reserves will be presented.
