Bracket, saw available for oil field tubulars cuts

A chain-mount bracket that attaches a universal air-powered saw to pipe and bar stock quickly for applications requiring multiple cuts in the shop or on the job site is available for oil field use.

The firm’s single cut bracket securely clamps the company’s APS-438 air powered saw onto a pipe or bar stock as large as 4 in. OD and allows it to make square cuts with ±1⁄16 in. accuracy. Operating on 90 psi air, this saw has a 3 hp motor, includes a standard grease fitting, safety throttle handle and relief valve, and uses either 10 in. or 12 in. fiberglass reinforced abrasive blades. The bracket and saw create a chop-off saw that is superior to reciprocating hacksaws, the firm says. The fiberglass reinforced blades are capable of cutting stainless steel, inconel, and other hard materials.

New velocity modeling methodology

A new velocity modeling methodology helps improve the quality and reliability of seismic data for greater accuracy in subsurface imaging.

US Patent No. 7,280,918 was issued Oct. 9, 2007, to the firm listed below for methods and systems used to combine seismic data and basin modeling data. The proprietary technology allows development of more precise earth models for the identification of prospects, well planning, and drilling operations.

The company’s patented velocity modeling methodology improves seismic data reliability by fully integrating basin geopressure modeling, geostatistical analysis, and seismic reprocessing, the company notes. More accurate pressure prediction in areas of poor velocity data quality and improved well placement and target qualification are included among features.

The geologic modeling integrates pore pressure, clay compaction, and compartment pressure modeling to produce synthetic velocities and pressure stratigraphy surfaces that better constrain seismic imaging, the firm points out.
