UDC 622.276 PREDICTING THE BEHAVIOR OF WATER AND GAS CONING IN Horizontal WellS
2015Co-Authors: Sh T Salavatov, Al Sayed GhareebAbstract:The applications of Horizontal Well Technology in developing hydrocarbon reservoirs have been widely used in recent years. One of the main objectives of using this Technology is to improve hydrocarbon recovery from water and/or gas-cap drive reservoirs. The advantages of using a Horizontal Well over a conventional vertical Well are their larger capacity to produce oil at the same drawdown and a longer breakthrough time at a given production rate. Coning is a term used to describe the mechanism underlying the upward movement of water and/or the down movement of gas into the perforations of a producing Well. Coning can seriously impact the Well productivity and influence the degree of depletion and the overall re-covery efficiency of the oil reservoirs. Delaying the encroachment and production of gas and water are essentially the con-trolling factors in maximizing the field’s ultimate oil recovery. Since coning can have an im-portant influence on operations, recovery, and economics, it is the objective of this paper to de-velop a computer program for calculating the critical oil (or gas) rate to avoid coning of un-wanted fluids into production Wells and to predict the behavior of water and gas coning in hori-zontal Wells

drilling Technology for Horizontal Well with long Horizontal sectionin santanghu tight oil reservoir
Oil Drilling & Production Technology, 2014Co-Authors: Qian FenAbstract:Tight oil exploration in Santanghu Basin enjoys a broad prospect, and Horizontal Well Technology is an important means for effective development of this region. This paper started with analysis of difficulties in Horizontal Well drilling in Santanghu tight oil formation and carried out research on key techniques such as Wellbore configuration optimization and profile design, specific drilling selection, low-cost and high-efficient trajectory control, increasing the encountering rate of reservoirs by Horizontal section and quality, and effective drilling fluid, etc. The paper has also developed supporting technique series suitable for optimized fast drilling of tight oil Horizontal Wells in Santanghu Basin, which has been successfully used in five Wells like Well Lu 101 and realized remarkable increase in drilling rate.

Horizontal Well Technology and performance
Reservoir Engineering#R##N#The Fundamentals Simulation and Management of Conventional and Unconventional Recoveries, 2016Co-Authors: Abdus Satter, Ghulam M IqbalAbstract:Many reservoirs that were considered not economically viable or technically challenging have been developed successfully based on Horizontal drilling Technology. Horizontal Wells are suitable in producing reservoirs in complex reservoirs with compartments, sealing faults and other lateral discontinuities. Horizontal Wells reduce the effects of water coning and sand production in reservoirs as the pressure drop in the vicinity of the Wellbore is lower than that of vertical Wells. Horizontal Wells are the solution to various Well problems, including high water cut and frequent workovers. In low permeability formations, Horizontal Wells can contact a large area for sustained production. Horizontal drillings are widely applied in both conventional and unconventional reservoirs. Horizontal Wells required to develop a reservoir are fewer in comparison to the number of vertical Wells. The cost of Horizontal Wells is generally three to five times greater than vertical Wells. However, an increase in Well productivity by several hundred percent is observed in most instances.

gas coning control with a smart Horizontal Well in a thin oil rim
2013Co-Authors: V VeskimagiAbstract:The use of Wells equipped with inflow control valves has steadily increased over the past decade. Most of these Wells are used to control the inflow from separate reservoirs or separate reservoir zones. This solution is particularly attractive for high-rate Horizontal Wells in thin oil rim reservoirs. Through the smart Well Technology, early gas or water breakthrough into the Well can be delayed or even reduced. The use of Inflow Control Devices (ICDs) and zonal flow control valves (FCVs) offers an opportunity to evenly distribute the drawdown along the Well, and therefore take corrective action if an early water or gas breakthrough occurs. In September 2011, Statoil completed Troll’s first subsea three-zone Horizontal smart Well. Just recently, anther Well on Troll with a similar completion design was put into production. One of the most important objectives in the study of Well Q-12BH, which forms the basis for this report, is understanding gas coning behavior. Without it, one would not be able to set appropriate operating strategies, and therefore optimizing production would simply not reach the wanted results. The approach taken begins by conducting an extensive literature review into coning control in thin oil rims and Horizontal Well Technology. Early production data of Well Q-12BH is studied, because knowing production history is a key into creating simulation models. These simulation models will analyze if the Well was put into production with the most optimal zonal valve opening positions and what could possibly be even better setting for such a Well.
