US Oil Drillers Add Rigs For 11th Week In 12

Sept 16 (Reuters) – U.S. drillers this week added oil rigs for an 11th week in the past 12, according to a closely followed report on Friday, although the rate of increases has slowed as crude prices remain below the key $50 a barrel level that spurs a return to the well pad.

That is, however, the longest streak of not cutting rigs since 2011 with the rig count increasing or holding steady every week so far this quarter.


Drillers added two oil rigs in the week to Sept. 16, bringing the total rig count up to 416, the most since February but still below the 644 rigs seen a year ago, energy services firm Baker Hughes Inc said.

The oil rig count plunged from a record high of 1,609 in October 2014 to a low of 316 in May after crude prices collapsed in the biggest price rout in a generation due to a global oil glut. That decline continued through the first half of this year when drillers cut 206 rigs.

U.S. crude futures were trading at around $43 a barrel on Friday after hitting a five-week low on renewed oversupply fears. They were on track to fall 6 percent for the week on Friday.

“With a large proportion of (rig) gains from smaller operators and oil now sub $45 we would not be surprised to see a flattening or even decline over the next few weeks,” analysts at U.S. financial services firm Cowen & Co said in a report this week.

Longer-term, however, analysts expect the rig count to rise slowly for the rest of 2016 before jumping higher over the next two years with a rebalancing of supply and demand. While U.S. oil futures for the balance of 2016 are only fetching around $44 per barrel, calendars 2017 and 2018 are trading near $48 and $50, respectively.

Analysts at Simmons & Co, energy specialists at U.S. investment bank Piper Jaffray, forecast total oil and natural gas rigs would average 498 in 2016, 704 in 2017 and 981 in 2018.

That, however, is not much higher than the average 479 oil and gas rigs that Baker Hughes said were active since the start of the year. In 2015, the total rig count averaged 978.

Since total rigs fell to 404 in May, the lowest since at least 1940, Baker Hughes said more than two-thirds of the additions have been in the Permian basin in west Texas and eastern New Mexico, the nation’s largest shale oil play.

Anadarko this week said it would boost capital spending and add four rigs by the end of the year, two in the Delaware basin in the Permian and two in the DJ Basin in Colorado.

Assortment of solids phase in oil drilling fluid

According to the different characteristics, there are different classification methods of the solid phase in drilling fluid.

  1. According to the role of solid phase in the drilling fluid, it is divided into useful solid and harmful solid phase.
  2. The solid phase is divided into high density solid phase and low density solid phase according to the density of the solid phase. High density phase is the weighted materials based on the drilling process requirements to increase the density of the drilling fluid, low density phase including the bentonite and treatment agent that required by configuration of the drilling fluid, and there are cuttings.drilling fluid7
  3. By whether solid phase and liquid phase is reacted, the solid phase in drilling fluid is divided into active solid phase and inert solid phase. The solid phase that can react with liquid is called active solid phase, and can not react with liquid is called inert solid phase. The former such as bentonite, clay and shale, etc, or such as limestone, granite, barite etc.

Drilling waste water treatment technology

For offshore drillings, one of the biggest drilling waste is sewage which grows out of drilling fluids, rain, water used to wash bits and cooling water. Usually, the under-treated sewage weighs 30 times the well-bore volume. Therefore, sewage minimization is a very vital part in the whole waste treatment.

However, as the easiest waste resource to be reduced, water can be reduced in such ways as below:

One-way cooling system can save water and seal it inside the system while eliminating cooling water, braking water and sealing water to achieve water recycling. It is proved that it is not pricey to recycle the water and is able to save a large amount of liquids.

The reason that rain can be recycled is the correlation between drilling fluids and water. Rain is applicable in washing drilling equipment. The water used to wash drilling equipment can flow into water tank just like rain and should be recycled till it cannot function any more. It will be surprising to see how many times they can be reused.

The dirtiest water ( such as, deserted drilling fluids ) can be applied to wash the panel. Desander and filter can produce massive deserted drilling fluids( usually there is one portion of solid phase in 2 or 3 portions of fluid phase ). They can be used to wash drilling mud tank. And shale shaker and decanter centrifuge also need washing water. Water used to clean panel do not need purifying since it is not necessary to wash away solid phase and liquid phase with clean water. It will be very difficult to separate them during treatment procedure.

It is necessary to produce sewage. It is quite expensive to treat sewage, so vacuum device is preferable to washing water here. A gun-shaped controller with tube is a good idea. The tube falls and automatically closes the connection to disconnect the controller. Drilling operators prefer high-pressure, small-volume washer due to the less labor intensity, better washing effects and reduced sewage volume. Generally speaking, both the vacuum device and washer are put into use when treatment is not costly. However, the gun-shaped controller will offset the cost.

Different approaches can be conducted to separate and treat waste, for instance, water-based waste and oil-based waste can not blend until being managed together. During the operation, fluid from drilling mud pits should be reinjected so as to flow into spare drilling mud pits.
