Drilling waste minimization is a method to reduce any waste generated from drilling operation. The ideal goal of it is to generate zero residue requiring final disposals. People have developed technologies for two main reasons which are project cost reduction and environmental protection.Typically,...

Actions of OPEC and free market factors were already in place to bring oil prices down. It is the stated goal of OPEC members to get oil trading between $75.-$80 bbl . The fundamentals for this price reducing goal were already in place, along with market forces which had oil predestined...

Pore pressure in shale is more than hydrostatic pressure; however the well does not flow because shale is in permeable. While drilling through pressured shale formation, pressure in shale causes fractures of shale due to stress crack. Shale finally falls into the well and results...

Overburden stress increases over depth (the more a well is drilled, the more overburden stress will be seen). When mud weight is not enough to support the overburden, the stress from the overburden will create shale fractures which will fall down into the wellbore. Finally, shale...

Cutting slip velocity is velocity of cutting that naturally falls down due to its density. In order to effectively clean the hole, effect of mud flow upward direction and mud properties must be greater than cutting slip velocity (settling tendency of cuttings). Otherwise, cutting...

This article will demonstrate you how to determine hole size by fluid caliper. First of all, you need to know what is the fluid caliper is. The fluid caliper is one simple way to calculate hole diameter. The concept is based on hole volume, annular capacity, and inner capacity....

Another late night researching OSHA confined spaces and H2S safety.Eagle Ford Shale is in my back yard, and started Crude Rig Washing LLC with my younger brother, we are two months in the works.I'm now fully comply with federal, state, general liability insurance, workers comp,...

Kill Weight Mud or Kill Drilling Fluid Density is the mud weight required to balance formation pressure. The kill weight mud may be pumped into the well at different time depending on kill methods (Driller’s method, Wait and Weight, Bull head, etc). How to determine kill weight mud?With the following equation, you can determine this figure. Kill Weight...

Trying to find someplace that a guy could get 1502 plug valves they are in short supply here in North Dakota and months out at the distributors in the state. If anyone knows where to find any i would be grateful for the info. Thanks Comment by Dwayne "Cactus"...

What it's Like To Be Oilfield TrashEveryday the headlines read something about the hardships hard-working American men  are causing on cities and towns where drilling is occurring.In Pennsylvania a Congressmen accuses oilfield workers of spreading sexually transmitted disease among his "womenfolks" as he calls them. The issue to him was never"What...

January 19th, 2012It's early in the new year and already we are seeing a number of catastrophic drilling accidents which include blowouts and deaths. Despite millions being spent by drilling contractors in training and HSE each year, the deadly pattern continues with the latest...

Cement volume calculation is based on annular capacity multiplied by length of cement as per cement program.This topic will demonstrate you how to determine cement volume as per specification and displace volume. After reading and understanding the concept, you will be able to apply...

 Associated Press LAGOS, Nigeria December 22, 2011 (AP)An oil spill near the coast of Nigeria is likely the worst to hit those waters in a decade, a government official said Thursday, as slicks from the Royal Dutch Shell PLC spill approached the southern shoreline.The slick...
