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.
The equipment is used as an alternative to intermediate casing and liners simplifying the well design. The liner stability to axial ultimate load is 100 kN/m, inside pressure - 15-30 mPa, to external collapse pressure - 8-20 mPa.
THe technology and equipment for local well casing does not have analogues in world practice of well construction. Total 15 authorships certificates of the former USSR, more than 45 patents of Russian Federation and 53 patents of the foreign countries, which include USA, UK, Australia, Canada, China, India, Norway, Japan, Germany, Mexico, Italy, France have been obtained for the technology.
Up to date the unique equipment have been applied in more than 1000 wells in Russian Federation and other countries of the former Soviet Union as an alternative to running intermediate casing strings. The technology has been successfully used in Vietnam, China, Egypt, Iran.

Local casing equipment can be used in open holes for the following:
- Successive local isolation of trouble zones during the process of drilling;
- Adding a length of the casing string from the bottom without loss of the well bore diameter;
- Shut off of the water producing intervals prior to running-in of the production string;
- Isolation of the individual intervals in horizontal wells;
- Suspension of liners in wells using profile hangers;
- Repair of casing strings.

- No need for the intermediate casings and liners;
- Tubulars and cement as well as power consumption are reduced, total rig time is saved;
- Improved quality and reliability of isolation operations in oil and gas wells;
- Improved quality of repair of the intermediate and production casing strings;

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.
It can be widely applied on the oilfields of Oman with the integrity and corrosion problems, such as Yibal.

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:
- Physical basic is the use of the scattered seismic waves for fracture studying;
- Field observation technology - the SVSL source and receiver apertures are positioned outside the scanned area to implement the sideview scanning applied in radar and sonic hydro location;
- Data processing: - the use of "conjugated focusing algorithms" providing focusing of the source and receiver apertures and the stacking multiplicity of 104 of seismic signals to identify scattered waves in the seismic wavefield;
- Geological interpretation based on the dependence between: - energy of the scattered waves and intensity of open fracturing in the 1st Fresnel zone; - the distribution of fracturing in a geomedium and its stress-deformed state (techno-physical models).

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.

Nuclear Magnetic Resonance Imaging (Tomography) for underground water exploration; (link to nmr.pdf)

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.
Parameters studied by the proton resonance in the geomagnetic field include the effective/flow porosity, pore structure, occurrence depth, specific capacity and water permeability of aquifer. AQUATOM consists of the portable PC, electronic units, wire loops and standard car batteries. The wire loops are employed for exciting and receiving NMR-signals using a specific multiimpulse method. The signals are recorded and processed through the proprietary algorithms and programs.
AQUATOM permits the detection of aquifers in several minutes after the start of the survey. Evaluation of the aquifer's geometry, porosity and permeability is possible after completing a full cycle of measurements, i.e. in two to three hours after the beginning of the operation. The survey can be conducted both in a profile mode and areally.

Seismo-Acoustic stimulation (SAS): (link to PulsarPosterEng.pdf)
Seismo-acoustic stimulation of a reservoir aims to increase the oil production rate by rousing elastic vibrations in a well opposite the pay zone layers for a long period of time (up to 15 days). The well can either be a production, injection or pressure-observation well.

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:
· Acceleration of gravity segregation of oil and water (up to 1 000 times)
· Increase of relative permeability ratio for oil in comparison with water
· Increase of speed (in scores of times) and completeness (up to 3 times) of capillary de-saturation of oil with water
· Increase of water and oil voluminal gas-saturation

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.
