Enventure is the global leader in the development and installation of solid expandable technology. Expandables are designed to provide a one-time, permanent solution for a multitude of downhole challenges.
Cold root rolling, an independent mechanical process that strengthens the connections in question, may offer the most innovative solution the industry has seen yet.
Over the past several decades, the oil and gas industry has adapted the technique of drilling horizontally through the reservoir in order to increase the surface area in contact with the reservoir as compared to drilling vertically through it.
The most stable type of floating rig, semisubmersibles are able to drill where jackups leave off -- working in waters measuring anywhere from 400 feet deep all the way up to ultra-deepwaters.
Drilling deeper, longer and more challenging wells has been made possible by improvements in drilling technologies, including more efficient and effective drilling fluids.
Enhancing safety on the rig, automated drillers cabins consolidate drilling controls, automated pipe handling controls, computer hardware and data processing systems into single temperature-controlled room on the rig.
An integral part of the drilling process, iron roughnecks connect and disconnect drill pipe. Whether pipe is being fed into the wellbore or it is being taken out, the iron roughneck uses a rotary table and torque wrench(es) to make up or break down pipe.
A drill bit is what actually cuts into the rock when drilling an oil or gas well. Located at the tip of the drillstring, the drill bit is a rotating apparatus that usually consists of two or three cones made up of the hardest of materials.
Drilling, completion and workover operations have evolved recently to offer development solutions for HP/HT wells that were previously considered uneconomical.
If not properly monitored, changes in pressure that can occur while the well is being drilled can cause combustible hydrocarbons to flow unchecked and at high pressures and flow rates.
Directional drilling has been an integral part of the oil and gas industry since the 1920s. While the technology has improved over the years, the concept of directional drilling remains the same: drilling wells at multiple angles, not just vertically.
LWD is a type of well logging that incorporates the logging tools into the drill string, administering, interpreting and transmitting real-time formation measurements to the surface.
News of the first FPSO and shuttle tanker in the GOM made waves through the industry when Petrobras disclosed its plans in 2007. Since 1920, the Merchant Marine Act has prohibited entry of foreign ships working between US ports.
A floating platform alternative that can support drilling, production and storage operations, the spar consists of a large vertical cylinder bearing topsides with equipment.
The significant financial perils of drilling an unsuccessful well on dry land are only magnified when the unprofitable well is drilled in several thousand feet of water.
Drilling for oil is an expensive gamble: With project costs
rising every year, an oil company can stand to lose an
incredible amount of money exploring or developing a
property that fails to yield hydrocarbons in commercial
rates.
Heavy oils are found around the world, with an estimated 69 percent of the world's technically recoverable heavy oil and 82 percent of the technically recoverable natural bitumen located in the Western Hemisphere.
Because heavy oil is so viscous, conventional methods, such as vertical wells, pumps, and pressure maintenance, are inefficient at extracting the oil. So, new technologies are being used to recover heavy oil including: cold heavy oil production with sand (CHOPS), vapor extraction (VAPEX), and thermal in situ methods.
Because the challenging, yet almost entirely untapped, deposits of heavy oil hold some of the largest reserves of hydrocarbons in the world. According to Bill Bush of the API, "Heavy oils, oil sands, and potentially shale, could contribute substantially to future U.S. and world oil supplies."
Thirty years ago communications between offshore facilities and onshore locations was limited to a two-way radio and daily reports. Back then, oilfield workers stationed offshore were virtually cut off from the rest of the world.
Allowing a previously domestic product to reach international borders, LNG is becoming a popular choice for stranded natural gas or overproducing regions.
Used to ensure products reach their intended destination, pumping stations are scattered throughout the pipeline to increase pressure in the line and monitor flow.
While natural gas production has increased in the North Sea, most of the natural gas being used in Europe is imported via pipelines from Russia, Central Asia, the Middle East and even Africa.
A massive transmission and distribution system, the natural gas pipeline network in the United States is comprised of more than 210 pipeline systems spanning 305,000 miles that can deliver to virtually anywhere in the Continental US.
There are three main ways that subsea pipe is laid -- S-lay, J-lay and tow-in -- and the pipelay vessel is integral to the success of the installation.
Hydraulic fracturing, a reservoir stimulation process that involves pumping fluid into a well to break-up sand and rock formations, has become a vital method for maintaining and improving oil and gas well production.
A form of unconventional gas, tight gas is locked in impermeable formations and requires secondary production methods to effectively bring it to the surface.
Acidizing is a type of stimulation that dissolves permeability inhibitors within the reservoir in an effort to increase or restore production from a well.
Artificial lift comprises various methods employed to bring oil to the surface, including sucker rod, hydraulic and submersible electric pumps, as well as gas lift.
A comprehensive, rapid response to a subsea blowout mitigates damage to the environment, protects the health and safety of the community, and minimizes economic impact.
When a current flows past a cylindrical object such as a riser, tendon, jumper or horizontal pipeline span, it creates a phenomenon called vortex-induced vibration (VIV).
A mooring system is made up of a mooring line, anchor and connectors, and is used for station keeping of a ship or floating platform in all water depths. A mooring line connects an anchor on the seafloor to a floating structure.
A new technology, subsea processing incorporates seafloor separation, injection and boosting to achieve production from challenging offshore environments.
Conduits to transfer materials from the seafloor to production and drilling facilities atop the water's surface, as well as from the facility to the seafloor, subsea risers are a type of pipeline developed for this type of vertical transportation.
Used on offshore oil and gas fields, a subsea tree monitors and controls the production of a subsea well. Fixed to the wellhead of a completed well, subsea trees can also manage fluids or gas injected into the well.
A type of remedial or well intervention operation performed on a producing well, coiled tubing is used as a cost-effective solution that can be employed while the well continues production.
