Tex replied to Dustin Frazier's discussion PSI Torque Gauge?
"I will reply to this one. I would have to believe that either the DW or the cat-heads did not just arrive from NOV. I would have to assume that these are not new Cat-heads anyway. There is no direct conversion between between psi or any hydraulic…"

Tex replied to Brandon "Rocky" Nichols's discussion Ton Miles
"Ifanyone can give you a direct #### answer to this question then I can assure youthey are wrong. On most rigs using 1-1/2" or 1-5/8" drill line thestandard is going to be between 2700 and 3000 Ton miles. This is when allcalculations are…"

Tex replied to Jeffrey Watts's discussion Non-sparking jaws for my pipe wrenches?
"Considering there are so many things on a drilling rig that could actually ignite gas on the rig floor, I think worrying about non sparking jaws in the pipe wrenches is going a little too far. The whole objective during the drilling, completion or…"

Tex replied to Tom Bonner's discussion Actual Weight On Bit
"Drilling high angle or horizontal holes WOB is not really WOB as far as indicator readings go. You must take drag trends and understand what you are looking at. It is different when using a motor or using a Geopilot with a rotating string. 70K down…"

Tex replied to Drilling Ahead's discussion How Do You Pump Your Sweeps & Pills? in the group Old School
"My preferred method of pumping a sweep ( which can in fact reduce the efficiency of a mud pump or partially cripple a mud pump) due to LCM material etc getting under valves is this. You must be sure where your sweep is and that is usually done by…"

What I believe may have happened on the Horizon

This is only my opinion, I can not prove any of it, but I think it will come to light.  Everyone is saying they can not figure out what cause the Rig to Explode so quickly, the loss of 11 souls, the failure of the BOP. It is not that hard to figure out. I have been in the drilling business for almost 40 years. I could not get exact information as to casing strengths and all the data that would have been helpful to come up with perfect calculations, but there is only one circumstance and…See More

Tex replied to stephen kemp's discussion How hydrocarbons break out of oil base mud vs water base
"That is a great reply about lowering the annular pressure to reduce the opening speed. There is another way also on a surface BOP. You can close off the accumulator bottles and open the bag using only the air or electric pumps. This greatly reduces…"

Tex replied to Drilling Ahead's discussion Transocean Investigation Results-Do You Agree With These Findings?
"What you do is correct, the only reason I say bbls in<>bbls out is because on these big rigs it can be done opposed to pumping directly from the sea chest. Even having two pits to take returns is easy. Return to one pit, then switch to the…"

Tex replied to stephen kemp's discussion How hydrocarbons break out of oil base mud vs water base
"It is serious business opening a BOP after a well kill. Much more critical in deep-water drilling, but your question was concerning a surface stack. If the annular preventer was used during a kill there can always be some gas trapped under the…"

Tex replied to Drilling Ahead's discussion Transocean Investigation Results-Do You Agree With These Findings?
"Normally on these rigs their pop offs would be set at 7,000 to 7,500 PSI. I believe that Trans ocean started using a rupture disc type pop off a few years ago. They are using 14p-2200 ( 14 inch stroke, normally 6" pistons with 2200 available…"

Tex replied to Drilling Ahead's discussion Transocean Deepwater Horizon Explosion-A Discussion of What Actually Happened?
"Number crunching? Some times it gets you into a mess instead of out of one. Always look for the reason for the action, not at the solution. Solutions are not always based on the problem at hand. Shut in well = no flow. Shut in well = no provable…"

Tex replied to Drilling Ahead's discussion Transocean Deepwater Horizon Explosion-A Discussion of What Actually Happened?
"The well is not 50% depleted. The shut in pressure at the well head is much lower then the formation pressure because the well is basically full of oil, not dry gas. With dry gas you would see a pressure at the well head almost equal to BHP. The oil…"

Pandora's Box

This profession has always had it's risk. Risk is controlled by good judgments, good planning and good practices along with evaluation of changing circumstances. Drilling exploratory wells are drilling into the unknown using past knowledge acquired to prevent future mistakes. Engineers have studied previous data from studies conducted to choose the location to drill and how to best enter into the formation with casing designs and other well planning. All of this is done on paper and with… Continue
