@petroleoamerica: shale gas. Pushing the envelope in deepwater cementing - Drilling Contractor. Reverse cementing, liquid additives are addressing narrow pressure windows and shallow-water flows, while new centralizers, subs are being engineered to get casing through increasingly tight restrictions By Kelli Ainsworth, Editorial Coordinator Cementing Highlights Cementing technologies and additives are being developed to help maintain a low ECD downhole in order to stay within narrow pore pressure and fracture gradient windows often seen in deepwater.Bowspring centralizers and centralizer subs are being engineered to pass through very narrow restrictions while still providing the necessary standoff.New liquid cement additives do not require pre-blending, enabling operators to adjust amount used on the fly.
As operators continue exploring and developing deepwater resources, cementing challenges have increased exponentially due to the very narrow pore pressures and fracture gradients typically seen in deepwater wells. Bringing reverse cementing to deepwater Navigating tight restrictions. How does Shazam work - Coding Geek. Have you ever wondered how Shazam works? I asked myself this question a few years ago and I read a research article written by Avery Li-Chun Wang, the confounder of Shazam, to understand the magic behind Shazam. The quick answer is audio fingerprinting, which leads to another question: what is audio fingerprinting? When I was student, I never took a course in signal processing. To really understand Shazam (and not just have a vague idea) I had to start with the basics.
This article is a summary of the search I did to understand Shazam. I’ll start with the basics of music theory, present some signal processing stuff and end with the mechanisms behind Shazam. You don’t need any knowledge to read this article but since it involves computer science and mathematics it’s better to have a good scientific background (especially for the last parts). Since it’s a long and technical article (11k words) feel free to read each part at different times. Pure tones vs real sounds pure sinewave at 20 Hz. Drilling innovations to simplify oil and gas exploration | In-depth | The Engineer. 11 September 2012 | By Stuart Nathan Drilling innovations aim to use less energy, materials and manpower to tap unconventional reserves When it comes to it, getting oil and gas out of the ground is pretty crude engineering.
The industry has a reputation for slow innovation, which in a sector that is inherently conservative for reasons of safety is not entirely surprising. If you’re going to drill through rock to pump a liquid out of the ground (especially if that liquid is flammable and accompanied by an explosive gas) then tried-and-tested technology is probably the best way to go. This, argues Shell’s head of wells R&D, Jan Brakel, leads to an interesting dichotomy.
‘We can fly aeroplanes with three hundred-plus people on board on full automatic over a distance of 5000 miles across the Atlantic ocean,’ he said, ‘but we cannot drill 5000 metres without continuous human intervention, using equipment that is still based on the basic design at inception.’ Mobile. Las Reformas | Reformas en Acción. Como se explicó en el apartado “El porqué de las reformas”, nuestro país requería un cambio radical. La magnitud de los retos que enfrentamos hacía necesario un impulso transformador que se concretó en 11 reformas estructurales, que fueron aprobadas en los primeros 20 meses de esta administración y durante el periodo de transición. Las reformas persiguen tres grandes objetivos: elevar la productividad de nuestro país, lo que detonará el crecimiento y el desarrollo económico de México; fortalecer y ampliar los derechos para que formen parte de la realidad cotidiana de los mexicanos; y afianzar nuestro régimen democrático y de libertades, lo que nos permitirá transitar de una democracia electoral a una democracia que brinde resultados concretos Seis de las reformas aprobadas responden al primer objetivo, elevar la productividad de México.
La reforma facilita el cumplimiento de las obligaciones fiscales, al tiempo que fomenta la incorporación de las empresas a la formalidad.
Syncrude. Minesite at Syncrude's Mildred Lake plant Syncrude Canada Ltd. is one of the world's largest producers of synthetic crude oil from oil sands and the largest single source producer in Canada. It is located just outside Fort McMurray in the Athabasca Oil Sands, and has a nameplate capacity of 350,000 barrels per day (56,000 m3/d) of oil, equivalent to about 13% of Canada's consumption. It has approximately 5.1 billion barrels (810,000,000 m3) of proven and probable reserves (11.9 billion when including contingent and prospective resources) situated on 8 leases over 3 contiguous sites. Including fully realized prospective reserves, current production capacity could be sustained for well over 90 years. The company is a joint venture between seven partners.
As a result, Syncrude is not traded directly, but rather through the individual owners. History Syncrude was formed as a research consortium in 1964.

Makes investment decision for the Mariner project. The Mariner Field is located on the East Shetland Platform of the UK North Sea approximately 150km east of the Shetland Isles.
"Statoil has extensive heavy oil experiences from offshore fields in Norway and Brazil. The Mariner field was discovered in 1981 and Statoil entered the license as operator in 2007 with the aim of finally unlocking the resources. We are satisfied that we now are able to make an investment decision for a profitable development of the Mariner field," says Lars Christian Bacher, executive vice president for Development and Production International in Statoil. "The Mariner project is a good strategic fit for Statoil. We are the world's largest offshore operator and have a portfolio of attractive projects in some of the most prolific basins in the world. Pending final approval of the field development plan by the UK authorities, Statoil expects to start production from Mariner in 2017.
The heavy oil project will require pioneering technology in order to be developed. Experts Discuss Horizontal Drilling and Hydraulic Fracturing During Toxicolog...

Using Halliburton’s automated rig activity measurement and reporting identification system, an operator in the Asia Pacific was able to reduce connection times in 12 ¼-in. well section by a total of 172 minutes. By Katie Mazerov, contributing editor An automated system from Halliburton aims to help the industry analyze rig activities to more precisely identify efficiencies and inefficiencies by measuring in detail the impact of each distinct activity on total rig time. “The challenge with conventional manual reporting is that the documentation is often difficult to understand and disseminate accurately,” Chris Marland, production champion, ADT Drilling Optimization for Halliburton, explained in a presentation at the 2013 IADC Critical Issues Asia Pacific Conference, 20-21 November in Bangkok.
“Resolution of that kind of data also can be limited because it depends on the attention to detail by the person entering the information,” he said. MaxActivity is a trademarked term of Halliburton. Apache’s Brander: Automation could help address invisible lost time in drilling | Drilling Contractor. Graham Brander, Apache Corp Graham Brander, director of worldwide drilling for Apache Corp, used to think that automation is something that should be left to rig contractors to worry about.
That changed after attending the SPE Drilling Automation Workshop in Galveston, Texas, last year. “(I used to think that) if there was some equipment we could pick up that helps us make the well a little bit more efficient, great,” Mr Brander said. “But after attending the workshop, I suddenly recognized that there is an opportunity here that we as a small independent in North America need to take advantage of.” Mr Brander was speaking during a panel presentation at a joint meeting of the IADC Advanced Rig Technology (ART) Committee and the SPE Drilling Systems Automation Technical Section on 28 February in Amsterdam.
There are a large number of stakeholders interested in automation technology, but there are also a number of challenges. Safety, versatility drive servicing innovations | Drilling Contractor. Often forgotten next to drilling, well servicing now attracts increasing investments to advance automation, HSE By Katie Mazerov, contributing editor A well pad with SAGD (steam-assisted gravity drainage) well pairs is part of Suncor Energy’s Firebag facilities in northern Alberta. In August, Suncor began field-testing a fully automated well servicing rig in the field. With an estimated 168 billion bbls of oil in place, the prolific oil sands of Alberta and British Columbia have been a pivotal factor in Canada’s ranking as one of the world’s top oil-rich nations.
Abundant with bitumen, with a typical well producing as much as 2,500 bbl/day of oil, many believe the SAGD (steam-assisted gravity drainage) market holds the future of oil for western Canada. Oil sands bitumen is described as relatively immobile, with a consistency similar to very hard rubber. To extract it with SAGD technology, most operators drill a pair of identical wells, one on top of the other. A millennial breakthrough.

Risk of Petrobras credit default climbs | Oil Patch Asia. Petroleo Brasileiro SA’s perceived creditworthiness is “deteriorating on concern the state-run oil company’s production will falter as it scales back drilling to offset losses sparked by Brazil’s fuel subsidies,” Bloomberg reported Monday. The cost to protect Petrobras’s debt against non-payment rose again last week. Oil and gas services company Halliburton expects Petrobras to reduce its drilling fleet in 2014 to cut expenses, adding to perception of heightened credit risk in the Brazil state-owned firm. Petrobras had set a goal to double production by 2020.
The drilling cutback threatens that plan. The company’s refining and supply unit lost $35 billion since 2011 when it began subsidizing imports under the government’s anti-inflation program. “It’s proof that the company isn’t doing what it is supposed to be doing,” Russell Dallen, the head trader at Caracas Capital told Bloomberg. 'Slowdown' forecast in E&P spend. The poll of 466 oil companies by US-based research firm Cowen & Company predicts the rate of spending growth in the international arena, excluding North America, to be cut more than half to 3.8% after two consecutive years of 8% spending hikes. Cowen attributes the trend to a “significantly reduced rate of growth” by major oil companies as well as lower expenditure by Asian national oil companies and budget cuts by Brazil’s state-owned Petrobras. High costs associated with exploitation of discoveries in challenging deep-water and harsh-environment areas have forced some companies to put the brakes on spending to maintain profitable returns for investors, while a global economic slowdown has also hit energy demand.
Oil companies including Statoil are now taking a more selective approach to projects to ensure profitability before committing to major investments in field developments. Illustration. Pemex y Banamex: radiografía de un escándalo financiero a gran escala. Foto: Cuartoscuro.Plataforma de exploración y producción de Pemex en el Golfo de México. El Banco Nacional de México (Banamex) es la institución financiera más antigua del país. Y ahora es también el centro de una polémica por la investigación que iniciaron autoridades mexicanas y estadounidenses ante un presunto fraude y lavado de dinero. Es un caso que va más allá de lo jurídico y que desnuda las prácticas de corrupción que existen en algunos sectores públicos de México, según especialistas. En la trama participa la empresa naviera Oceanografía, una de las contratistas más importantes de la paraestatal Petróleos Mexicanos (Pemex), y que desde hace varios años ha sido señalada de operar irregularmente.
