US land rig count falls by four, offshore grows by two


The number of land rigs drilling for oil and gas in the US fell by four this week, according to the Baker Hughes weekly rig count. There are now 924 land rigs. Meanwhile, this week saw an increase of two rigs offshore, growing from 21 to 23 rigs. This puts the total US rig count at 950. Last year at this time, there were only 462 rigs drilling in the US.

US total rig count holds steady


The US total rig count remained at 952 this week, according to the Baker Hughes weekly rig count. Although the land rig count increased by one, the number of rigs drilling in inland waters dropped by one unit. There are 21 rigs drilling offshore US. Last year, there were 447 total rigs in the US.

New digital age may disrupt traditional business models


By Linda Hsieh, Managing Editor The length and severity of this downturn have triggered a lot of discussion around the industry’s business model. Much of the discussion has centered around revising the traditional dayrate model to incentivize performance, but do such bonus schemes go far enough? The drilling industry is at the cusp of an inflection point in its digital revolution. From automation to robotics, from data analytics to artificial intelligence (AI) – every day new technologies are pushing the industry ever closer toward changes that could significantly disrupt the business model as we know it. Numerous other industries have already undergone such disruptions, typically with new-to-industry “disruptor” companies coming out on top. “Uber is the world’s largest taxi company, ...

Small signs hint at possible recovery in still-sluggish North Sea

The ENSCO 120 jackup is scheduled to begin a three-year drilling program in the North Sea in July. It was the first rig equipped with Ensco’s Canti-Leverage Advantage system, which enhances the rig’s hoisting capacity at the farthest reaches of the cantilever when the rig is fully skidded out, leading to fewer rig moves on multiwell programs.

Although the North Sea drilling market is still quite a ways from what one might call healthy, small signs of recovery are starting to sprout. Several operators, for example, have publicly touted significant reductions in their breakeven costs for offshore projects – from Maersk Oil’s $40-45 range for pre-FID projects to Statoil’s $27 for pre-FID Norwegian Shelf projects...

Study targets potential for gas loading in drilling fluids to improve influx detection, management

Figure 2 depicts mixture density vs. pressure for different gas-oil ratios of methane-base oil mixtures at 150°C.

Well control is a continuous and top priority for maintaining safe and efficient drilling operations. Particularly during deepwater and HPHT drilling, potential gas kick situations can be more difficult to detect topside due to the expansion potential of reservoir influxes. To detect gas influxes, knowledge of the interaction between natural gas and the drilling fluid at relevant process conditions is critical...

US rig count falls falls for first time in six months

Offshore default

Since January, the number of rigs drilling for oil and gas in the US has been steadily increasing. However, the number of oil rigs dropped by two this week, reaching 756 units, according to the Baker Hughes weekly rig count. The number of gas rigs increased by one. This puts the total US rig count at 940, compared to last week’s 941. One year ago, there were 431 rigs drilling in the US.
