Onshore Oil Drilling

The days of “black gold” squirting out are history

Oil exploration initially meant drilling relatively shallow holes more or less straight down. This is the symbolic picture of the “easy oil” era. Today, oil companies use sophisticated directional drilling to drill snake and weave-shaped undergrounds to find pockets of oil and increase recovery from a single well. The days of the oil pump turning continuously and “black gold”
just squirting out are history.

The drilling of bores into underground formations is accomplished using an elongated "drill string" built from a number of tubular drill pipe sections coupled at their ends, which carries the drill bit or other cutting tools. The drill string extends from the surface into a well or "wellbore", which is formed by the rotating drill bit.

The drill string, which frequently contacts the surrounding bore hole casing, inevitably suffers from frictional wear, shock and abrasion, causing similar damage to the surrounding casing. If this persists, the casing is worn thin and will eventually rupture. A shut-down is then necessary, with lengthy and expensive remedial work before the casing is restored to a fully effective condition. Frequently, the productive life of a well is wholly determined by the integrity of its bore hole casing.

We have experience in extending the life of:

  • Stabilizers
  • Kicker plates
  • Pumps
  • Valves
  • Shafts
  • Bearings
  • Actuators
  • Gates
  • Drill bits
  • Mills
  • Cutter wheels
  • Holeopeners
  • Wear bands
  • Subs

Offshore Oil Drilling

We optimise your drilling activities

Nowadays growing trends include offshore drilling, deep water drilling, pre-salt drilling and shale fracking. Offshore drilling, with today’s advanced technology, allows a larger amount of the drilling to be done in the same well. Although this gives cost and logistic advantages it is also greatly increasing wear on the drilling string and casing. This wear and the string/casing friction (where they touch) are critcal to the drilling efficiency operation.

A common wear solution is the hardbanding of the drill pipe "tool-joints" using oil industry standard alloy weld overlay. However, there is a general increase in demand to find more efficient solutions to extend equipment lifetime. Within the field of hardbanding services on drill pipes, Trio OilTec Services utilises a specially designed one-of-a-kind hardbanding system.

The system is developed to grind off the old hardbanding, pre-heat the tool joint steered by temperature sensors and cooling in the center of the pipe to control the heat and protect the liner inside. Equally important in the hardbanding concept is the introduction of the pioneering hardbanding wire Castolin OTW-12Ti, or exceptionally wear resistant Trio MX5 coating.

Conventional Gas

Worldwide consumption projected to double by 2030

Gas is approx. 30% less carbon-intensive than oil and about 50% less than coal. As a cleaner burning fuel, natural gas offers solutions to our economic and environmental challenges, qualifying as an ideal partner for a low carbon future. Natural gas is also the fuel of choice for energy efficiency, since it shows a higher conversion rate than other fossil fuels when producing electricity or heat. The 22 % worldwide share of gas in the power generation industry is projected to augment due to the overall aging of power plants, as well as the low costs, speed of construction and flexibility of natural gas-fired power stations.

Another advantage comes with the fact that natural gas requires little processing between the extraction source and the end customer. Transported safely and efficiently in its liquefied form (LNG) either by dedicated tankers or a network of pipelines, gas can be delivered across continents. In its gaseous form, transport through underground pipelines and storage in caverns are equally harmless for the environment and population. An additional resource not to be neglected is represented by biogas or “green gas”, obtained through biomass combustion.

Shale Gas

Tapping into undiscovered reservoirs

Shale gas refers to natural gas trapped within fine-grained sedimentary rocks, previously impenetrable. Extracting gas from shale involves drilling down, sometimes thousands of meters, and then sideways as much as 1,400 m. Once a well has been drilled, water, chemicals and sand are pumped in at high pressure, which fractures the shale. The grains of sand prop open the fissures in the rock and allow gas to flow from the shale into the well. The technique goes under the name of “hydraulic fracturing” ("fracking") and employed in conjunction with horizontal drilling enable gas extraction from shale at affordable costs.
