... Abstract It is possible to set a special packer within the long completion horizontal interval to establish an injection zone and a production zone, and a new flooding scheme of simultaneous injection and production in a single-hole horizontal well drilled for developing thin marginal heavy oil...

... Abstract It is very difficult to obtain the right variograms in the geostatistics to build an exact 3D geological model for the fluvial facies reservoir. This paper discusses how to calculate respectively the horizontal and vertical variograms based on the horizontal well data and vertical well...

.... The study has been divided in three parts. The first part relates to the use of downhole heaters in thick sands, stimulating both vertical and horizontal wells in the reservoir. The second one evaluates the temporary application of downhole heaters in horizontal wells for a limited period of time...

... is completed and includes more than 300 horizontal wells. SINCOR produces 200.000 bbl EHO/d today. Prior to a second development phase, answering to the question: "what have we learnt of the aquifer risk?", should help making the next development phase more efficient. Some of the main lessons learnt...

... affecting the project: reservoir oil viscosity, permeability and effective footage of the horizontal well. This analysis revealed the best strategy for the appraisal of the well planning and led to the approval of a 2000m horizontal well. On a second stage of the study, after the successful drilling...

...% of the reserves. Actual production is 36.1 thousand BOPD with a gas/oil ratio of 390 ft 3 /bbl and 33% water cut. By November 2001, 52 horizontal wells out of 55 were active. The horizontal wells produce 18.6 thousand BOPD or 51.6% of total production per day. Petrophysical and Reservoir Characteristics...

... Abstract The Tulare Steeply Dipping Horizontal Well Project is a multi-year project that is designed to recover oil by steamflooding the Tulare and Amnicola sands in the Cymric and McKittrick fields in the San Joaquin Valley, California utilizing horizontal producers and associated vertical...

... horizontal well project. A water cut of 70% was predicted at the end of the prediction run. The third water injection project (Fase II) was selected as an inverted seven-spot injection pattern ( Figure 3 ). The water flooding started in noviember 1985. In this pattern the injection and production wells...

... to drill from kick off point to horizontal hole in these reservoirs was about 40 days and 60 days, respectively. At the present,out of 28 drilled wells,6 wells are horizontally,7 wells are directionally and 15 wells are vertically.Only two wells in I 1 reservoir are horizontally(well 15 and well 21...

... Abstract Horizontal wells are becoming popular for primary and enhanced oil recovery operations because of unique advantages of horizontal wells in comparison to those for vertical wells. For example, horizontal wells are being used, at present, for the primary recovery of heavy oil worldwide...

... to the experts is the norm not the exception. In just over one year of horizontal drilling operations Petrolera Ameriven drilled approximately 110 horizontal well bores with nearly 564,000 feet of lateral lined section. The lined drain holes had a cumulative 90% net sand contact rate. These results far exceeded...

... with relatively high associated costs, precluded an early development. Economic cold development was made feasible in 1992 by the introduction of horizontal wells in Mukhaizna. The development strategy for the field includes an initial conventional "cold" development, which is economically attractive in its...

... duallateral well using a cemented junction was successfully completed in Mukhaizna. Two previous trials have failed due to operational and design reasons. This paper presents the evolution of well design in Mukhaizna and the benefits of utilising horizontal wells and downhole junctions. It also contains...

... Abstract Over 500 horizontal wells have been drilled into the Cummings/Dina channel trend between Senlac and Winter since 1990. These wells produce 13 – 14 API oil with a gas free viscosity of 3600 cp from a depth of 700 meters. Production peaks at about 20 to 60 m3/d oil with 10% water...

The approach is based on the exact solution to a task of the horizontal well productivity evaluation in a 3D reservoir with correct evaluation of all boundary conditions including...

... The production process of horizontal well is first considered as a comprehensive production system integrating the flow in reservoir with that in wellbore. This consideration ensures not only the optimum design and production in parts, but also that in the whole production system. We apply...

... Abstract This paper presents results of the laboratory investigations leading to development of a novel, radically different waterflooding process, which is gravity stable. The new process is called Toe-To-Heel Waterflooding (TTHW) and uses vertical wells for injection, while horizontal wells...
