Services provided by TATNEFT in Oman:
During the visit of the joint delegation of Ministry of Oil and Gas and Petroleum Development Oman in May 2003, the technologies mentioned below have been marked as "unique" and being able to have an "immediate impact on the oil production rate" in Oman. It has been also noticed, that TATNEFT possesses a vast number of other innovative technologies, which can bring the value to the oil and gas industry of the Sultanate.
Equipment for local well casing and casing string repairs (Expandable tubing):
JSC TATNEFT has developed equipment for
local well casing using sections of the profiled expanded liners without
cementing and without loss of well bore diameter.
Local casing equipment can be used in open
holes for the following:
It has been mentioned in MOG report, that
the above technology has been developed almost 30 years ago and has an
excessive history of application.
Side view seismic method (SVSL): (link to the file svsl.pdf)
An advanced method of seismic exploration amed at mapping the spatial (3D) and time-spatial (4D) distribution of open fracturing in a geomedium.
Differences of the SVSL method compared
with other methods of seismic exploration:
Seismic location of open fracturing by back-scattered waves (SLOF) - the modification of the SVSL method. (link to slof.ppt)
Side-view seismic location (SVSL) and Seismic location of open fracturing (SLOF) methods are based on irradiating the explored volume of geomedium with elastic waves and registering the back-scattered ("back" means "in source direction") waves. Both methods give an information about distribution of open fracturing zones in geomedium. The core distinction is in fact that the SVSL method finishes data processing after such information is obtained. This information then is used for interpretation. In the SLOF method, this information is considered only preliminary and processing continues with the use of special software in order to get more accurate location, size, shape and intensity of individual zones of open fracturing. No additional information about distribution of elastic waves velocities in the explored volume is used by these corrective procedures.
The proposed NMR technology employing NRM
tomograph AQUATOM helps engineers to evade drilling dry wells and polluting
underground water, and to reveal water-promising areas not only in complex
and poorly studied hydrogeological areas but also in profoundly studied
ones. It also permits the dramatic minimization of exploratory drilling.
AQUATOM has been successfully tested during three years in various types
of aquifers, including porous, karstic and fractured ones in Europe, Asia
and Australia. In the Russian Federation this method is registered under
patents ## 1079063, 1436247, 1686669 and 2039947.
Seismo-Acoustic stimulation (SAS): (link
This stimulation differs from acoustic or seismic ones as it emits an intermediate frequency range (20 - 3000 Hz). The acoustic stimulation (10-30 kHz) is intended for clearing the bottom-hole, seismic stimulation (20-40 Hz) is carried out mainly from the surface and has the same objectives as seismo-acoustic one. However the main stimulation zone is located near-surface and that's why it is less efficient for bed deposition depths exceeding 1 000 meters. Besides the seismo-acoustic frequency range is more favorable for such stimulation.
The main effects appearing while elastic
waves pass rich porous media are the following:
EOR by oil soluble non-ion surfactants;
Technological process is recommended for
the application on the oil fields with terrigenous heterogeneous oil reservoirs,
being developed by contour flooding method.
Selective HCL treatment of carbonate formation (link to HCL.doc):
Technology is designed to increase the well productivity at the expense of putting on production of non-operating zones and interlayers of productive formation;
Light units for the well work-over; (link to lightUnits.pdf)
