Electrical submersible pump (ESP) systems are critical to achieving the maximum production rates and reservoir pressure drawdown that improve ultimate recovery. But variable volumes of gas in unconventional wells can pose challenges for performance of the ESP.

Wellbore position is computed from survey measurements taken by a measurement-while-drilling (MWD) tool in the bottomhole assembly (BHA).

Cementing is central to the discussion of zonal isolation and well integrity.

Saudi Aramco operates a large offshore oilfield development that has driven achievements in multilateral and extended-reach directional wells.

Eight of the world’s 10 longest wells have been drilled by ExxonMobil as operator of the Sakhalin-1 project in Russia.

This work demonstrates cement design that includes evaluating cement-sheath mechanical integrity in intercalated salts.

A great benefit of being the SPE president is the chance to interact with students and young professionals around the world. Many are anxious about the future. I have been asked if this is the worst time ever in the oil business, a question that made me smile.

Operators in the North Sea have been concerned about the ability of the cement sheath to maintain sealing integrity because of the increasing number of reported failures in mature wells. This paper presents results from a new laboratory setup to visualize the source of issues.

Many wells in the Cana-Woodford shale suffer from chronic sustained casing pressure (SCP) because of poor cement-sheath bonding.

The development of multilateral wells and long-reach wells has become important to maximizing recovery for many fields. These technologies are often applied in offshore environments, where large reservoir areas are drained from one or more platforms.
