Banyu Urip crude contains 26% wax, which can lead to flow-assurance challenges in a crude pipeline exposed to lower temperatures. Injection of pour-point-depressant (PPD) chemicals has been...

The Permian Basin currently has more crude than it can handle, and production there continues to grow at a steady rate month-over-month after surpassing 3 million B/D earlier...

... that can definitively characterize a crude oil for asphaltene risk and control that is scalable to the field. The answer to why this is lies in the sheer complexity of the asphaltene molecule itself and, just as important, the variances in asphaltene type and content from crude to crude. As production...

...Stephen Rassenfoss Shell and Marathon have agreed to sell most of their oil sands operations. Exxon Mobil recently removed 3.5 billion bbl of the ultraheavy crude from its proved reserves because it no longer plans to develop them any time soon, following a similar move by ConocoPhillips...

...Nathan Meehan President's column Last December I had the pleasure of returning to the Kingdom of Saudi Arabia and touring the giant Manifa oil field. Manifa produces a heavy, sour crude oil from six, long (up to 40 km), stacked reservoirs in shallow water (Arukhe 2014). The shallow waters have...

... that there was no incompatibility issue between microemulsion-treatment formulation and the formation crude and formation water. Nonetheless, it was considered important to veri- fy this observation because emulsion was observed during the post-treatment well cleanup. Treatment-Fluid Options for Re- covered Field Samples and Fluid...

...John Donnelly Editor's column US companies began selling crude oil on the international market last month shortly after the US Congress ended the country’s 40-year-old ban on oil exports. The action is another byproduct of the US shale revolution and will do little to settle the current fight over...

... of organic, inorganic, or mixed scale deposits. Such operations extended the average ESP run life from 40 to 140 days and eliminated the need for workover (WO) rigs. A heavy-crude viscosity reducer (HCVR) is recommended as part of these treatments, to improve the cleanup process. Introduction Recent work...

The program demonstrates how sustainable commercial flow rates can be achieved through the selection of a suitable completion design—including a downhole electrical submersible pump (ESP) and a downhole diluent-injection strategy—and through keeping within...

... of the year, the Manifa field will have the capacity to produce 900,000 BOPD of Arabian heavy crude, 90 MMscf/D of gas, and 65,000 B/D of condensate. The project consists of 42 km of causeways, 3 km of bridges, 27 drilling islands, 13 offshore platforms, 15 onshore drilling islands, water supply wells...

What started as a better option for pumping cold, heavy, sandy crude in Canada has been adapted for high-volume production of heavy crude in Venezuela, for lifting medium-weight oil mixed with things that other pumps cannot...

...Stephen Rassenfoss Alberta Heavy Oil Nearly 2 million bbl of ultraheavy crude are produced each day from Canadian oil sands, but the notion of also producing bitumen from reservoirs made of carbonate rock can spark skeptical remarks. They are likely to say something like: “Carbonates are very...

...Casey McDonough Technology Focus When the first pipelines moved crude from wellhead to market in the early 1870s, it was difficult to balance the product in the line to the storage tanks at each end. If the receiving station was not ready for the crude, the sending station risked pumping too much...

... and Exhibition, Abu Dhabi, 23-25 January. The paper has not been peer reviewed. Kuwait Oil Company started free gas production from its Jurassic sour-gas field in May 2008 with the commissioning of Early Production Facility (EPF) 50. The field produces sour gas and light crude from a deep high-pressure/high...

Both are powered by electricity, though they use it quite differently. The motivations are the billions of barrels of crude in formations where current methods...

..., it will allow heavy-oil producers to use significantly less steam per barrel to coax out thick crude. Lowering the steam/oil ratio (SOR)—which represents the barrels of water used to produce an added barrel of oil—could offer a profitable path to reduced emissions. “If you can improve the thermal efficiency...
