Special Focus

Examining trajectory effects can improve horizontal well performance

As applied to potential development of an Alaskan field, vertical permeability problems can be solved by using an analytical model to design a horizontal well with undulations.

Extending the reach of ERD: How far can we go?

Several technologies now exist that, when combined, will allow extended reach drilling to achieve astonishing lengths. However, the cost of these technologies—the business case—will be unique for each situation.

Onshore ERD wells prove RSS effectiveness for Alaska

A North Slope ERD record of 13,379 ft was set at Alpine field by optimizing point-the-bit RSS with a “matched," extended-gauge drillbit.

Slotted liner design for SAGD wells

For steam-assisted gravity drainage wells, staggered slot and gang slot patterns show better performance in FEA models than overlapping slot patterns.

Solving centralizer damage in ER horizontal multilaterals

Extensive modeling and yard testing were used to solve the problem of damage sustained after centralizers exited casing windows at West Sak field.


A new depositional model for the deepwater Wilcox-equivalent Whopper Sand—Changing the paradigm

Perhaps the Gulf of Mexico became isolated during the Lower Tertiary, which would explain a series of events that led to deposition of thick, extensive, mostly sandy reservoirs more than 200 mi from shore. These reservoirs are now being explored.

New web resource offers guidance on produced water

A US Department of Energy-sponsored website attempts to help operators manage an increasingly costly waste stream.

Optimizing multi-stage separators' pressure set points maximizes oil recovery

In a simulation, the proposed, simple procedure increased oil production and API gravity at no added cost.

Understanding the chemistry of clear brine fluids is vital for best performance

Achieving cost-effective performance begins with matching well conditions with brine properties.

Virtual sources can yield real results

A virtual source can be any seismic sensor that, through some simple mathematics, is then moved around in new ways to get interesting results.

Special Report

Dual and intelligent completions optimize Algerian producing gas wells

At Hassi R'Mel field, dual completions could significantly improve output from multi-zone gas wells, but results from intelligent completions look even better.
