Unconventional/complex reservoirs
Ranger acquires American Well Services for $90.5 million, adding 39 workover rigs and boosting its fleet by 25%.
The merger creates one of the largest oil-focused independents in the US with output of 526,000 BOE/D.
BPX Energy will retain operatorship of the assets after the sale of its interests to private investment firm Sixth Street is complete.

Unconventional resources are often in good supply, but difficult and expensive to develop. To develop unconventional resources, technologies like hydraulic fracturing and horizontal drilling are key, and higher oil prices will help. -
This work presents a workflow that can be used to analyze and forecast time/rate data of wells in low-and ultralow-permeability reservoirs.

The careful planning and successful execution of a multistage-fracture-stimulation completion in one of the first horizontal wells (KZN-F) drilled in the Amin formation in north central Oman instigated a step change in initial production rate and long-term deliverability from this tight-gas-sandstone reservoir. The operator and service company worked as a team, modeli…

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 The fluids produced at surface no longer represent the original reservoir fluid.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…

In this second article of a series covering water management in hydraulic fracturing (HF) in unconventional resources, the properties and characteristics of the flowback fluids are discussed, together with the general categories of technologies that are best suited to treat them.

Recent industry activities have turned their focus to the areas of liquid-rich shale (LRS) and light tight oil (LTO) along with unconventional tight and shale gas.

Unconventional gas is poised to enter its Golden Age and to effect positive global change if it can meet three challenges. Consider the 7 billion people on Earth who use energy each day.

Many different completion techniques, such as vertical-well multiseam completions and multiple lateral wellbores drilled into a single coal seam, have been used to develop coalbed methane (CBM) reservoirs.

This paper presents a pragmatic approach to frame, evaluate, and compare appraisal strategies in resource plays.

As oil companies have moved to more-marginal reservoir targets, application of conventional techniques has often yielded disappointing results, and tighter zones are often abandoned for more-promising target intervals.
