Saudi Aramco's new R&D centers in the US will help bridge international scientific expertise and technology.

This is the last column I will write before the end of my tenure, and I could not think of a better subject to discuss than volunteerism in our global society.

When drilling offshore wells, the most common method is to drill with a single gradient fluid with the fluid column extending from the bottom of the well back to the drilling rig.

Intelligent completion systems have the ability to monitor and optimize reservoir performance in real time without mechanical intervention.

Government, industry, and labor representatives met recently to discuss solutions to the technical skills shortage in the global oil and gas industry. Although the discussion was wide-ranging, the group came to a consensus on several key points.

When interviewing potential senior-petrophysicist recruits, we exchange pleasantries to break the ice and then I ask an easy, yet fundamental technical question: “How would you explain Archie’s law to an inexperienced colleague?” Then, I sit back in expectation of a slick answer from the candidate. Imagine my surprise when the interviewee takes a sharp intake of breat…

The evaluation of complex carbonate reservoirs is a challenging task, and a detailed understanding of reservoir heterogeneity is still lacking. In this study, the effect of static rock type and sample size was investigated on special-core-analysis laboratory (SCAL) data derived from capillary pressure and resistivity-index experiments at reservoir temperature and net …

Accurate determination of relative permeability hysteresis is needed to predict water-alternating-gas (WAG) injection reliably. Two series of gas/water relative permeability hysteresis curves were obtained from corefloods under mixed-wet conditions. The results revealed that none of the widely used hysteresis models (e.g., Carlson and Killough models) is able to predi…

Drillstem testing of low-permeability reservoirs is challenging because high-pressure drawdown around the wellbore lowers fluids below saturation pressure and creates two-phase flow into the wellbore. The fluids produced at surface no longer represent the original reservoir fluid. This paper shows the benefits of a careful methodology of data selection and equation-of…

My, what a difference a year makes as I look back at last year’s interest vs. this year’s. Improved-oil-recovery (IOR) technology and remotely-operated-vehicle support were in the forefront last year. This year, the buzz is around high pressure/high temperature (HP/HT). This is not to say that IOR technology has vanished or become passé; far from it. But this year’s g…
