写岩石散装密度和中子孔隙率

这Lithotrak™散装密度和中子孔隙度from Baker Hughes delivers the most accurate LWD porosity measurements under challenging hole conditions. Accuracy of porosity measurements is the critical element in formation evaluation. A single p.u. porosity difference in a large field can cause an error of hundreds of millions of dollars in booking reserves.

这LithoTrak service offers measurement of formation density, neutron porosity, borehole caliper, and formation imaging. Because this is real-time information, you can geosteer the well for maximum reservoir exposure.

Neutron porosity and bulk density are critical for the quantification of hydrocarbons in the reservoir. When used with other formation evaluation measurements, such as gamma ray and resistivity, you can make several determinations. These include type of hydrocarbons, reserves in place, total recoverable hydrocarbons, asset dollar value, and profitability. You can also evaluate water saturation and analyze geological structure using these measurements.

优化井眼稳定性

You can also generate full, circumferential borehole images that give information about borehole quality, bed boundaries, and structural dip azimuth of the formations being drilled. LithoTrak borehole images and azimuthal density measurements are used in real-time reservoir navigation for accurate wellbore placement in highly deviated and horizontal wells.

如果您对岩性有任何疑问，光电效应（PE）可以提供其他岩性信息。Lithotrak方位角卡尺测量用于井眼稳定性应用，并通过管理等效的循环密度（ECD）和钻孔参数来降低昂贵的钻井停机时间。

当与声学数据结合使用时，密度测量可用于生成合成的地​​震图以准确地与地震相关。这对于在地质不确定性高的地区进行准确的井眼位置很重要。您可以将密度与声学数据相结合，以确定井眼稳定性应用的岩石强度。

这LithoTrak service’s uncompromising accuracy and reliability is designed to operate under 30,000 psi (2,068 bar) in harsh deepwater environments.
