Special Focus

Casing wear in extended reach and multilateral wells

Long rotating times and severe doglegs can jeopardize casing integrity.

Electromagnetic MWD improves drilling performance in the Fayetteville

The use of real-time MWD data and reliable directional control resulted in increased average ROP and reduced drilling time.

Failure investigations deliver reduction in nonproductive time

During three years of Shell’s NPT reduction initiative, failure frequency for GOM drilling tools has declined 60%, from five to less than two failures per month.

Fayetteville Shale wells benefit from cementless lateral technique

A new whipstock-and-packer approach to drilling openhole laterals can reduce rig time and risk by eliminating the need to set cement.

Features

Multicomponent seismic exploration: A more complete conversation

Integrating converted shear-wave data with traditional P-wave data provides reservoir insights.

Precise well placement technology revitalizes brownfield environments

Batch horizontal drilling campaigns in Western China deploy unique real-time bed boundary mapping technology to target thin oil columns and rejuvenate an onshore brownfield.

Quantifying downstream effects of hydrate inhibitor injection

Use of industrial methylated spirit was considered critical for flow assurance in an HPHT subsea tieback, but could impact processing and product quality.

Recent advances in well logging and formation evaluation

New developments include geochemical logging tools, through- and near-bit sensors, slimhole NMR, and improved mud-logging and gas-extraction technology.

SHALE ENERGY: Developing the Haynesville—A cooperative model for US shale gas development

A recent Wall Street Journal editorial commented that an accompanying article in that newspaper “makes the case that huge natural-gas discoveries in shale rock are on the verge of, well, changing everything.”

SHALE ENERGY: Developing the Haynesville—Effects of petrophysical factors on Haynesville fluid flow and production

High geopressure gradient and initial production rates cause an overall rapid decline in production, with first-year decline rates up to 80%.

Shale Energy: Developing the Haynesville—Mergers and acquisitions support sustained Haynesville drilling

Shale E&P activity continues to grow through strategic joint ventures designed to reduce risk and improve pipeline takeaway.
