12:05–1:15PM

Geochemical Methods for Determining the Origin of Stray Gas in Aquifers Near Oil and Gas Wells: Mark McCaffrey, Geoscience Manager of Interpretive Services, Weatherford Laboratories

As the pace of drilling in the United States has increased, so has the number of alleged incidents of stray natural gas migration to shallow aquifer systems. Using examples from the Barnett and Marcellus gas resource play areas, this talk presents the geochemical methodology for determining if gas in an aquifer is, or is not, related to petroleum development activities.

PRE-CONFERENCE SHORT COURSE – SUNDAY, AUGUST 24

$895 | Colorado Convention Center

8:00AM–5:00PM

Introductory Geochemistry for Condensate-Rich Shales and Tight Oil Instructor Christopher D. Laughrey (Weatherford Labs, Golden, Colorado)

The course is a practical and applied introduction to geochemical techniques routinely employed in shale-gas condensate and tight-oil reservoir assessment. The emphasis is on explaining which tools and techniques can best address specific questions, what caveats must be kept in mind when employing these tools, what are the strengths and limitations of petroleum geochemistry in resource plays, and how to interpret conflicting data from different analyses. Theory is kept to a minimum and select practical exercises help participants learn to review geochemical data, recognize problems with the data and begin to cultivate a feel for interpreting geochemical data and integrating these interpretations with other geological information. Includes digital course notes and refreshments. Limit 50 people.

SAVED WELL FROM P&A, PLUS $1.5 MILLION in expenses by enabling running and reaming to TD

CleanReam™ casing shoe overcomes 3 months of NPT and extreme hole conditions

After 3 months of failed attempts at reaching a total depth (TD) of 10,741 ft (3,274 m), an operator was faced with plugging and abandoning (P&A) a new well, which would incur additional expenses of at least US $1.5 million. Weatherford deployed the reaming-with-casing system and CleanReam premium reaming shoe, which enabled the project to reach TD in one run and save the well from P&A.

PETROLEUM CONSULTING | EAGLE FORD SHALE, USA

Integrate reservoir and geomechanical data to optimize fracture and well placement.

SAVED 4 STAGES AND $400K through optimized fracture placement

FracAdvisor™ framework enabled comprehensive understanding of the reservoir, reduced costs

Petroleum Consulting used the proprietary FracAdvisor index—a unique algorithm and framework for shale—to optimize fracture placement. After examining 11 reservoir and rock qualities, the consulting team discovered the optimal design should be 4 stages fewer than the planned 15, which saved the client US $400,000 in completion costs.

WELL ENGINEERING/PROJECT MANAGEMENT | OFFSHORE LATIN AMERICA

Take a collaborative, engineered, results-based approach to achieve uncompromising well integrity and start-to-finish project optimization.

SAVED $80 MILLION PER WELL in NPT costs
