... Abstract Multiple fractured horizontal wells (MFHWs) are considered as the most effective stimulation technique to improve recovery from low permeability reservoirs particularly tight and shale assets. The understanding of the complex flow behaviour and predicting Productivity Index (PI...

... into reserves in reservoirs previously believed uneconomic. Horizontal wells and hydraulic fracturing are two complementary technologies that, when combined, can reduce, halt, or even reverse this declining trend. The first hydraulic fracturing treatment in the North Sea was conducted over 40 years ago; since...

... measured by CGDS. The drilling bit is equipped with “eyes”, which can identify oil/gas layer during drilling. Since 2011, we have provided CGDS geosteering services in 29 horizontal wells in Songliao Basin. The total footage reached 18255m, and the longest footage in horizontal section was 1325m in single...

... in optimising horizontal multifrac completion technologies used to complete unconventional US onshore wells. The developing technologies and techniques are increasingly being used for offshore applications and have found widespread use in horizontal wells in areas such as the southern North Sea. This case...

... The development plan included an ERD horizontal well to target several thin pay zone reservoirs. The well needed to be horizontally placed in the target to optimally drain the thin oil-bearing sands. The paper will further discuss the development of two main thin, oil-bearing reservoirs by ERD...

... Abstract Horizontal wells with one or more branches have been used to maximize reservoir contact by Statoil and other oil companies for more than a decade. Frictional pressure drop and variation in permeability and mobility will naturally lead to non-uniform inflow profile along a well...

... Abstract Formation characteristics are predicted using an advanced computational mathematical method and using hydrocarbon-gas and drilling data as input. Robust predictions of porosity and saturation are made in vertical and horizontal wells, in clastic and carbonate reservoirs. The potential...

... Abstract The thin and laterally extensive Al Shaheen reservoirs are developed with extended reach horizontal wells and large-scale water injection, which over the last decade has proved to be a proficient and environmentally favorable recovery scheme. This paper describes how injection water...

... as a pre-requisite for a commercially attractive development. The first development phase in 2004 comprised three long reach horizontal wells drilled from the nearby Halfdan field. These wells enabled early development of the gas utilising existing facilities. During this phase it was realised...

... Abstract There has been a tremendous growth in the number of high-angle and horizontal wells in the past decade. Coupled with the increase in water cut from various brownfield environments, these high angle wells present us with complex reservoir and production management challenges. Fit...

... drain hole systems. Abstract This paper presents an analysis method of the transient pressure behavior of dual lateral wells. Conventionally lateral wells have been analyzed using horizontal well analysis techniques. As we will show in this paper, that if the phase angle between the two lateral...

... Abstract This paper describes how 4D seismic data have been incorporated into the modelling and management of the Andrew and Harding reservoirs. These two fields pose similar challenges in that both use horizontal wells to produce from a 50 - 100 m oil column between gas cap and aquifer...

... are presented. The results are promising, and show the potentials of non intrusive techniques for flow monitoring. It is expected that a combination of several sensor principles would facilitate the interpretation of downhole flow conditions. Introduction There is a trend to use more horizontal wells...

... Abstract Carefully positioned horizontal wells are helping to maximise recoverable reserves from both new and mature North Sea producing fields. In many cases, the economic performance of these wells is very sensitive to position within the reservoir. For example, displacing the horizontal...

... ABSTRACT We have successfully tested a new concept for a down hole tool, a Well Tractor, that significantly reduces operation costs for servicing horizontal wells. The Well Tractor is a cost effective alternative to the very expensive and time consuming conventional drill pipe conveyed...

... of the well. A 5750 m well with a 630 m horizontal section at a TVD of 4780 m under 92 degrees inclination was drilled. Drilling the well broke several records, being the deepest horizontal well drilled and logged with the deepest liner run to TD, cemented, completed and stimulated. In the horizontal section...
