Dr. Keith Millheim and Tom Williams gave a presentation, November 2nd, 1:45 p.m., "Evaluation of Well Testing System for Three Deepwater Gulf of Mexico (GOM) Reservoir Types"   

Abstract:

This paper discusses the results of a research project co-funded by Research Partnership to Secure Energy for America (RPSEA) & Industry “Early Reservoir Appraisal, Utilizing A Well Testing System” which incorporated a study utilizing historical deep water production data to show the need for conducting well testing in most Gulf of Mexico (GOM) reservoir discoveries. The project took reservoir data from three major deep water plays. The project analysis and evaluation included eight deep water well testing systems for subsea wells in the Gulf of Mexico (GOM). From the reservoir data sets a complete series of simulated well tests were run: short term and long term tests, interference tests, and injection tests. Also, nodal analyses of the various simulated tests were done. This paper provides a general oversight to the various well tests. The well test system architectural designs and operational feasibility analysis give all the available options for deep water well testing in regards to downhole, subsea, surface, and vessel requirements, with an extensive focus on safety requirements. Providing this information to industry professionals and operators allows for more accurate decisions when justifying the production capacity and commerciality of a field / reservoir.

Paper Presented:

Coiled-Tubing Intervention and Drilling System Using Cost-Effective Vessels (130688) K.K. Millheim, T.E. Williams, C.R. Yemington, Nautilus International   

Abstract:

The primary objective of this project is to design a cost effective deepwater Coil Tubing (CT) system for down-hole work in deepwater Gulf of Mexico satellite wells without need for a Mobile Offshore Drilling Unit (MODU). Our system uses conventional CT equipment, a vessel of opportunity, and a modular, reusable Self Supporting Riser (SSR) to reenter seafloor trees. This work will facilitate improved resource recovery from existing satellite wells and make it practical to develop reservoirs that would otherwise not meet economic hurdles.
 

Paper Presented:

Expediting Exploration and Development of Deepwater fields in West Africa, Dr. Keith K. Millheim  Read More

Abstract:

This paper explains why billions of barrels of deep water oil and gas, already discovered, will not be developed in the foreseeable future, using the conventional deep water technology practiced by almost all the oil companies. The paper also explains why companies will not pursue a great many hot prospects for exploration in deep water when the prospects look too small. The paper introduces another possible, non-conventional approach for exploiting what is considered marginal deep water prospects, both discovered and yet to be discovered. This enabling technology and its impact on all aspects of exploration, drilling, evaluation, early production, and intervention are explained in this paper. Like any new technology that is considered a disruptive technology it requires champions who will defy the conventional ways of doing things and to take the risk for doing something new. This paper describes a new business model that can be used by West African IOCs and NOCs to expedite the development of what is considered marginal deep water fields.
