  • Lessons Learned from Water Shut-off of Horizontal Wells Using Inflatable Packers and Water Shut-off Chemicals in the Ghawar Field of Saudi Arabia
    2013
    Co-Authors: Hemant K. Sharma, Jorge Duarte, Eid Mufeed, Saadoun Turki, Jose R. Vielma
    Abstract:

    Due to the advancement of technology and improved capabilities of drilling horizontal wells, producers and injectors are now commonly completed with long horizontals to expose large reservoir areas. For the reservoir pressure maintenance, the most prevalent means is by using water injection. This injected water, while helping in pressurizing the reservoir, becomes a curse when it starts to produce with the oil. In addition, as the transmissibility of the water is higher than the oil, water breakthrough is a major challenge facing the oil industry. Various techniques are available and being used worldwide to control/reduce this produced water; however, controlling water production by performing water shut-off (WSO) in horizontal wells is more complicated and challenging than in vertical wells. To control water production in horizontal wells, isolation of the wellbore using inflatable packers in open/cased hole completion and capping with cement has shown little success in the past. Therefore, another technique was attempted to control water production in horizontal oil producers by using mechanical means to isolate the wellbore and chemical means to isolate the matrix/fissure, which forms a permanent barrier and reduces water production. The selection criterion for mechanical isolation and type of chemical suitable for the formation is a tedious task for the Petroleum Engineer. Most of the time, the vendor’s data that is available is being used and applied for the field application, which shows a low success ratio. In this paper a brief overview has been presented, taking into account two wells from Ghawar field in Saudi Arabia, where a combination of wellbore isolation using inflatable packers and matrix/fissure isolation using an organically cross-linked polymer (OCP) system were performed. The candidate selection criteria, job criteria, planning, execution, and post-job evaluation will be discussed.

  • Geopressure modeling from petrophysical data: An example from East Kalimantan
    AAPG Bulletin, 1994
    Co-Authors: Herkommer
    Abstract:

    Localized models of abnormal formation pressure (geopressure) are important economic and safety tools frequently used for well planning and drilling operations. Simplified computer-based procedures have been developed that permit these models to be developed more rapidly and with greater accuracy. These techniques are broadly applicable to basins throughout the world where abnormal formation pressures occur. An example from the Attaka field of East Kalimantan, southeast Asia, shows how geopressure models are developed. Using petrophysical and Engineering data, empirical correlations between observed pressure and petrophysical logs can be created by computer-assisted data-fitting techniques. These correlations serve as the basis for models of the geopressure. By performing repeated analyses on wells at various locations, contour maps on the top of abnormal geopressure can be created. Methods that are simple in their development and application make the task of geopressure estimation less formidable to the geologist and Petroleum Engineer. Further, more accurate estimates can significantly improve drilling speeds while reducing the incidence of stuck pipe, kicks, and blowouts. In general, geopressure estimates are used in all phases of drilling operations: To develop mud plans and specify equipment ratings, to assist in the recognition of geopressured formations and determination of mud weights, and tomore » improve predictions at offset locations and geologically comparable areas.« less
