In-situ retrofit sets milestone in deepwater MPD evolution

Brian Barbee, Ensco; Chad Henry Wuest, Scott Bremner, Julmar Shaun Sadicon Toralde, Weatherford International

Close collaboration drives unprecedented on-site integration of full, closed-loop drilling on a DP semisubmersible, and provides new insights into the evolving technology.

Features

Marginal wells re-drilled economically using directional CT and underbalanced conditions

Toni Miszewski, AnTech Ltd.

Directional coiled tubing technology, including the rig and purpose-built BHA, provides a multitude of advantages compared to conventional rotary drilling systems.

What’s new in well logging and formation evaluation

Stephen Prensky, Consultant, Silver Spring, Maryland

This review is based on published technical papers and publicly available literature. The author does not endorse any specific technologies or service providers. The logging systems may be available as commercial services, or still in development and testing phases.

ShaleTech Report

Accelerated production improves shale well economics

Josh Jolly, Theo Baughn, Southwestern Energy; Gene Little, Experitec; Terry Cox, Al Majek, Emerson Automation Solutions

Low natural gas prices have placed production economics under ever-increasing scrutiny. The rapid decline rates of unconventional wells challenge operators to maximize returns over a short period. One solution has been realized, by means of improved management of the free-flow cycle of gas wells, through the application of surface automation.

Enhancing production from unconventional reservoirs with micro-proppant

Jeff Dahl, Devon Energy Corp.; Philip Nguyen, Ronald Dusterhoft, James Calvin, Shameem Siddiqui (1), Halliburton

Incorporating micro-proppants in the pad fluids of an already optimized fracture design provided a significant uplift in well productivity in an 11-well study.

Assimilation of drilling data produces reliable, cost-effective, engineered completions

Dale Logan, C&J Energy Services

Process improves reservoir recovery without the expense of running open-hole logs.

Engineering effective and efficient completions

Robert F. (Bob) Shelley, StrataGen

Data-driven modeling and on-site analytics allow operators to optimize their completions, thereby increasing EUR and delivering a better ROI.

Efficient, multi-zone testing enhances re-frac design and implementation

C. O. "Doc" Stokley, Consultant

A multi-zone testing tool, which originally proved to be an efficient, inexpensive means of performing tests of selected intervals in laterals, has had its use extended to multi-lateral wells.

World Oil's 100-Year Anniversary

Post-war expansion: The tables are turned

The Post-War era brought rising oil production to both the U.S. and countries worldwide.

OPEC: Unification of the world’s petroleum producers

In the 1960s, Arab nations, which relied heavily on oil revenue, were being frustrated by oil price cuts made by Western oil companies. Another problem was the import caps imposed by the U.S. government, which also depressed prices.

More changes, expansion occurred at Gulf Publishing Company

World Oil’s November 1957 issue announced that at age 32, William (Bill) G. Dudley had been elected V.P. of Gulf Publishing Company (GPC).

Suez Crisis: A threat to European oil supply

In July 1956, Egyptian President Gamal Abdel Nasser announced the nationalization of the Suez Canal, which was a primary conduit for oil export shipments.

Six-Day War: A shipping blockade leads to captured fields

The Six-Day War of June 5-10, 1967—the third major Arab-Israeli conflict in history as of that date—was caused by the continuing Arab rejection of Israel and an Egyptian blockade of Israeli shipping.

Prudhoe bay: Discovery of Alaska’s oil giant

Richfield Oil Corp. began running seismic survey crews on the northern coast of Alaska, bordering the Arctic Ocean, in 1963.
