Immiscible mixed gas enhances EOR economics, increases permeability in swelling clays

A mixed gas (CO2, N2, CO) is uniquely applicable for increasing matrix permeability and enhancing oil recovery rates. It also decreases the Mcf/bbl ratio and increases the mobilization of asphaltenes while operating at immiscible conditions on oils ranging from 18° to 42°API.

Recovery improved in a brownfield heavy oil well, using inflow control technology

Using AICDs in heavy oil fields can reduce water cut. As a case study shows, the viscosity difference between heavy oil and water provides a favorable mobility ratio well-suited to this technology, and increased oil production.

What’s new in artificial lift?

Part 1: In this first of two monthly reports, the authors review significant changes in the artificial lift industry and highlight innovations in beam/rod pumping, linear lift units, and more.

A practical approach to fluid integrity management in secondary recovery

A waterflood system’s success ultimately depends upon formation geology and the mobility ratio of the produced oil and injection water. Both new and mature waterfloods can benefit greatly from improved fluid integrity management, as demonstrated in a maturing waterflood in eastern Kansas.

Shaletech: Scoop/Stack

Oklahoma’s entries in the national shale playbook sound like an encrypted play call in an American football game: SCOOP, STACK, Merge, SCORE.

Reliable sand detection helps to optimize separator efficiency, prevent costly shutdowns

Awareness of sand build-up in separator vessels is crucial to their efficient operation. The latest vibrating fork level detectors provide greater visibility of sand deposits, helping to avoid unplanned shutdowns and improve production efficiency.

Former Oxy chief assembles new Texas-based powerhouse operator

Former Occidental Petroleum Chairman Steve Chazen, and his partners at private equity firm TPG Pace Energy, have acquired assets from well-respected Texas firm Enervest to form a new, $2.66-billion operator, Magnolia Oil & Gas.

Satellite/aerial imaging identifies structural anomalies and presence of hydrocarbons

A direct detection technology identifies fundamental properties generated by the interaction of super-light elementary particles. These small, sub-atomic particles constantly emit an intrinsic radiation spectrum that can be tracked to draw inferences about mineral deposits.

Regional Report: Latin America Is Latin America’s fragile market cracking under pressure?

Despite the rise in crude prices, many Latin American countries are still grappling with considerable debt and declining production rates.

First Oil

The fates of two venerable producing countries’ E&P sectors hang in the balance, as national elections approach.

Energy Issues

Not that many months ago, I wrote about bots, particularly chat bots, that are evolving as a threat to our day-to-day operations.

What's new in exploration

Rising oil prices, along with shale being over-extended, and world reserves declining, are requiring companies to look to exploration again.

Drilling Advances

The ascension of dual-activity rig floors, which enable different operations to be conducted simultaneously in parallel, is credited with helping reduce offshore well delivery time.

What's new in production

Looking through rose-colored sunglasses, some people see renewable energy as eventually, and perhaps completely, replacing oil and gas.

Oil and gas in the capitals

On April 3, Vietnamese state firm, PetroVietnam, issued the following and unusually blunt statement on its website: “The East Sea is forecast to continue to have uncertainty this year...affecting the company’s efforts to attract foreign investors to invest in its open offshore fields.”

Water Management

I promised to cover some specific produced water management trends.

Executive viewpoint

The Permian basin’s output is forecast to reach 3.18 MMbopd in May, according to EIA, and it is widely anticipated to become the world’s largest oil patch.

The last barrel

If Edwin Drake would have drilled his 75-ft oil discovery well in northwestern Pennsylvania, down another 3,900 ft, he might have discovered vast quantities of natural gas in the Marcellus shale.
