This year's annual Downhole Geology lineup features stories that dive deep into the way technology is helping geologists to better understand the subsurface. That theme is reflected on this month's cover, created by Rusty Johnson. The top and bottom photos show the UPR Rock Island 4-H well in southwestern Wyoming, a horizontal well that was a major success thanks to improving downhole technology and a better understanding of the region's geologic history.

 AAPG Backs Further Climate Study
Four Policy Statements Approved

The AAPG Division of Professional Affairs' Governmental Affairs Committee has produced a total of nine statements since 1998 that have received the Executive Committee nod. Recently four Policy Statements concerning issues facing the upstream industry were approved at an October meeting.

 Deep Horizontal Experiment Taps Tight Gas
It's a 'Frontier Play' In Green River

About five years ago a leader in horizontal drilling teamed with the U.S. Department of Energy's Energy and Technology Center and GRI in a $10 million research project. Their goal: Evaluate the technological and economic feasibility of drilling horizontal wells in fractured, but very-low permeability sandstone three miles below the sage brush flats of southwestern Wyoming. Today the team can now point to an unqualified success with the UPR Rock Island 4-H horizontal well.

 Images Are a 'Bit' Novel
Real Time Data A Problem-Solver

Real-time well analysis that takes place during actual drilling helps manage deviations that are too small to detect with seismic data, but could interefere with drilling. 1998 Pacific Section H. Victor Church awarded for a poster session on a project in Ventura, California, shares the "Advantages of Real Time LWD Dipmeter Data."

 Case Studies Show Value
Downhole Tool Gets Real Tests

Nuclear magnetic resonance wireline tools have become an important part of many companies' operations. How important? Case studies from wells in the Gulf of Mexico and on the Gulf Coast illustrate just what NMR can add to the overall downhole picture.

 A Natural Phenomena
Seeps Give a Peek Into Plumbing

Oil and gas seeps have provided resources that have been recorded everywhere. Their importance led to a symposium, field trip and workshop on this topic at this year's AAPG Pacific Section meeting. Drawing earth scientists from across the United States and around the world, it served as a forum for the development of a plan for the global analysis of fluid seeps.

 But They Have to Act Like One
Teams Usually Win Competition

Pilot test attempts to prove that MDTs are more effective and profitable.Here's one company's story.

 Geology of Art
Class 'Rocks' for Students

10 years ago Art and the Earth Sciences debuted as a one-hour course at Indiana University-Purdue University in Indianapolis. It has now expanded into a three-hour couse with labs. This popular course blends art and artifacts with the science of geology. It impacts to the lives of students who would never think of stepping into a science lab.

 GEOPHYSICAL CORNER
Maps: It's the Basements Fault

The basement fault block pattern started last month contiues. This month the authorl attempts to substantiate the claim that many oil and gas fields are controlled by basement. Some geologists may concede that the evidence for underlying basement control is convincing.

 Commentary: Teamwork 'Savvy'
Required Geology Continues to 'Deliver'

How much effort is going toward improving recover from already producting fields? A survey taken of nearly 300 AAPG members in five U.S. cities by the AAPG Reservoir Development Committee may surprise readers with their answers.
