Applications

Horizontal and Extended Reach Drilling Wells

Horizontal and extened reach drilling wells increase the value of drilling operations as they can reduce environmental impact and the cost of offshore equipment and pipelines.

Construction of horizontal and extended reach drilling wells require high quailty pipes and thread connections able to withstand extreme torques, high compressive, tensile, and fatigue loads as well as able to meet strict requirements to dimensions and clearence to be run down the hole.

We offer OMK’s premium thread connections that comply with the highest standards for well construction under extreme conditions and guarantee safe operation.

Offshore Fields

Offshore oil and gas projects impose highest requirements for cost efficient and environmentally safe solutions to assure production and well integrity.

This is due to many factors, such as complex well geometry with tensile, compressive, and bending loads, simultanious increased reservoir pressure effect and elevated well temperatures as well as corrosive environments.

All of this threaten the integrity of an offshore well and there is no room for errors.

These projects require high quality OCTG pipes with proven and qualified premium thread connections of special steels and steel grades as well as the option of dope-free technology.

Our range of pruducts for offshore projects is designed to meet these criteria .

Offshore OCTG pipes are manufactured per API Spec 5CT, PSL-1, PSL2, and PSL-3 while OMK’s premium connections have successfully completed ISO 13679 CAL IV tests and guarantee long term safe operation of offshore wells.

Casing While Drilling

Today, oil and gas well casing while drilling has become a reliable alternative to conventional drilling operations. This solution helps optimize well construction costs, increases drilling efficiency and safety by minimizing personnel impacts and reducing the number of people required to run a drilling rig.

However, drilling in the presence of wellbore instability or limited space and material require a simple, yet safe, drilling method as well as close attention to the design used.

Our tubulars with their premium threaded connections demonstrate outstanding fatigue properties and are capable of withstanding high operating torques while assuring reliable pipe performance in a well under ultimate loads.

Heavy Crude Oil Production

Extended reach drilling and horizontal wells increase the value of drilling operation as they can reduce environmental impact and the cost of offshore equipment and pipelines.

Construction of horizontal and extended reach drilling wells require high quailty pipes and thread connections able to withstand extreme torques, high compressive, tensile, and fatigue loads as well as able to meet strict requirements to dimensions and clearence to be run down the hole.

We offer OMK’s premium thread connections that comply with the highest standards for well construction under extreme conditions and guarantee safe operation.

Hard-to-Recover Reserves

The development of hard-to-recover reserves is becoming a requirement for a successful oil business, and for many oil companies involved in the development of such reserves, this has long been of strategic importance.

Hard-to-recover oil and gas reserves are field, deposit, or block reserves characterized by relatively adverse geological conditions or physical properties of the petroleum. properties of such difficult-to-recover reserves normally include low reservoir permeability or porosity, thin formations, high viscosity as well as areas of abnormally high reservoir pressure and gas content. Difficult reserves also include oil from under gas caps or from oil rims. The problems here are uncontrollable gas break-through into oil wells and a low oil recovery factor. Whereas recovery of high-viscosity petroleum is complicated by low product mobility, difficulty in lifting it to the surface and in subsequent transportation. In any case, these are reserves that are impossible or extremely difficult to recover economically using conventional methods.

Principal development interests include oil rims, Achimov sequences, Paleozoic deposits, and source rocks (Bazhenov and domanik suites). By this time, Upper Jurassic deposits are already being developed on an industrial scale, and development of Middle Jurassic and Paleozoic sediment as well as the Achimov suite is well underway. Oil and gas companies are also looking for an efficient method of producing from the Bazhenov suite.

The primary technologies for difficult reserves that Russian oil and gas companies are considering include improved horizontal well design with multi-stage frac operations, construction of high-tech branched wells, gas injection in mixing mode, integrated engineering and improved modeling of geologically complicated areas.

Development of low-permeability formations, for instance, is driven by advances in formation stimulation technologies, primarily frac, where companies have progressed from the first relatively simple horizontal wellbore wells with a horizontal branch of up to 500 meters in length and multi-stage frac operations of 6 to 10 stages to horizontal branches that are 1,500 meters in length with 24 to 30 frac steps with high proppant injections rates and a complex frac fluid cocktail.

These well construction technologies require reliable strong tubulars and threaded connections capable of reliable operation under extreme conditions. OMK’s custom designed high-torque threaded connections as well as high-grade tubulars are capable of withstanding extreme loads and assuring reliable trouble-free well operation.

Mature Fields

When developing mature fields, priority must be given to cost efficient solutions. As fields reach maturity, several injection wells are normally drilled in the same area to maintain current production levels. This causes water flooding in the producer wells, which, in turn, results in an increased risk of corrosion, threatens equipment integrity, and results in greater operating costs and lost profit.

Therefore, priority in the second and third phases of operation must be given to cost-efficient solutions.

Our tubulars with premium threaded connections will assure reliable operation and help extend the lives of your wells.

Low-Temperature

We have capabilities that enable us to manufacture low-temperature pipes for extreme well construction conditions beyond the Arctic Circle with ambient temperatures down to -600C.

The metals used for these pipes have high plasticity and impact toughness at below-freezing temperatures. Low-temperature properties are tested using the Charpy impact bending test at -600C followed by inspection to see the percentage shear in the specimen.

Low-temperature pipes are manufactured in all grades per API Spec 5CT, GOST 31446-2017, and GOST 632-80 and are marked with an additional letter code such as LT or ХЛ (Russian)

Examples: R95 LT, P110 LT,  Lxl, Mxl
