Cooper Energy hires Ocean Monarch rig for Otway basin drilling

first_imgOil and gas company Cooper Energy has hired a rig for a drilling program in the Otway basin offshore Australia.Cooper Energy said in its quarterly financial report on Wednesday that it had hired Diamond Offshore’s semi-submersible rig, the Ocean Monarch, for drilling of the Annie and Elanora prospect.The company added that the Ocean Monarch would begin drilling the Annie-1 and Elanora-1 wells in June 2019. The work on the two wells will begin following the drilling of exploration wells by Cooper and Esso Australia which is set to begin in February 2019.David Maxwell, managing director of Cooper Energy, said: “We have the flexibility to pursue the growth opportunities in our portfolio and have acted quickly, securing a rig and committing to drill two attractive gas prospects in our offshore Otway acreage.“We expect the coming six months to be as momentous as any in the company’s history as Sole is completed; we drill the Annie and Elanora prospects in the offshore Otway Basin; conclude gas contracts and, prepare to acquire the Minerva Gas Plant with the upside it offers for our operating margin, cash generation and production.”The Annie and Elanora prospects, located in the VIC/P44 license in the offshore Otway basin, hold best estimate prospective resources of 71 bcf and 100 bcf respectively.The Annie prospect is a simple amplitude supported structure located seven kilometers from a pipeline tie-in point. The primary reservoir targets are the Waarre C and Waarre A Formations which are the productive reservoirs in the Casino and Minerva gas fields.According to Cooper, the chance of finding gas and proving a minimum developable resource size at Annie is estimated at 56%.On the other hand, Elanora is a large amplitude supported structure that straddles VIC/L24, VIC/L30, and VIC/P44, located ten kilometers west of the Casino gas field and approximately six kilometers to a pipeline tie-in point.The prognosed reservoir, Waarre A Formation, is the same as the producing offset fields at Casino, Henry, and Netherby. The company believes that the chance of finding gas and proving a minimum developable resource size at Elanora is estimated at 44%.Annie and Elanora is operated by Cooper Energy which holds a 50 percent interest while Mitsui E&P Australia and Peedamullah Petroleum hold 25 percent each.Worth noting, this is not the first time the company is using the Ocean Monarch rig for its operations. Cooper used the rig last year for the Casino and Sole offshore wells.last_img read more

Redknapp: I’m not under pressure

first_img “It is up to Tony what he does. If he is not happy come and talk to me – I’m a big boy. I’m going for dinner with him. I’m not going to be there buying him dinner to keep my job – I will let him buy dinner. “The impasse over my contract is that I wasn’t bothered about signing a new contract, not in the slightest. “What is a contract? A contract is you work for a club. If they don’t want you, you talk to the chairman, sort out what you’re doing and you move on. “If we stay up and at the end of the year Tony wants to talk about another year with me I’d be delighted, that is what I want to do in my life.” Fernandes has backed Redknapp since he was chosen as the man to replace Mark Hughes in November 2012. Liverpool striker Daniel Sturridge faces another two to four weeks on the sidelines, according to a report. The 25-year-old England forward has been out of action for six weeks due to a thigh strain he picked up on international duty. He had been thought to be close to a comeback but, according to the Liverpool Echo, pulled his calf during training on Thursday and could now be absent for up to another month. “Daniel has pulled his calf,” Liverpool boss Brendan Rodgers told the newspaper. “He’s looking at being out for another two to four weeks. “It’s a big blow as we were looking forward to welcoming Daniel back. He has worked tirelessly. “But we have other players training hard and working hard and we will turn to them. It’s why we bulked up the squad in the summer.” Sturridge is now set to miss Sunday’s game and the midweek Champions League clash with Real Madrid at Anfield at the very least. Rodgers, meanwhile, has leapt to the defence of Raheem Sterling, but insists there is no club versus country row between him and England manager Roy Hodgson. The 19-year-old forward has found himself pilloried in the last week after Hodgson revealed the youngster had told him he was tired ahead of the Euro 2016 qualifier in Estonia. Sterling was left out of the team for that match, coming off the bench to win the free-kick from which Wayne Rooney scored the only goal, which led to accusations he had said he did not want to play. Rodgers totally rejected those accusations. “He (Sterling) has been absolutely incredible for me and what has been nice to see is his maturity as a young man; he’s 19, a full international and he will hopefully be a key player for England and Liverpool for many years. “This is a kid we bring up to be responsible and honest – lots of players will tell you they haven’t played when they haven’t felt right but this is a kid who didn’t say that. “What he was saying was he felt tired. I’ve had it a number of times here with Raheem where he has been tired in his legs but he has gone on to play in games and be exceptional.” QPR boss Harry Redknapp does not want any assurances over his position and insists he is not under pressure at Loftus Road. Press Association But, with a home game against Liverpool to come on Sunday, Redknapp does not believe his job is under immediate threat if recent results do not improve. When asked if he was feeling any pressure, Redknapp said: “None whatsoever. ”Until you’ve been under pressure you don’t know what pressure is and I’m not under pressure, none whatsoever. I’m looking forward to the game on Sunday. ”We have played seven games, we are seven games into a Premier League season. We have played three home games, we got beaten by Hull 1-0 and missed a penalty, we beat Sunderland and drew with Stoke in a tough game – it is not easy. ”I still have every confidence in the players here that we will start getting the results, and hopefully that will start on Sunday.” Redknapp’s current deal at the club expires at the end of the current campaign and for weeks he had been expected to sign an extension. But the former West Ham and Tottenham boss is not concerned about negotiating a new contract and is still enjoying a close working relationship with Fernandes. “I don’t need assurances from anybody,” he said. The 67-year-old guided the Hoops back into the Barclays Premier League through the play-offs last year, but the side have struggled on their return to the top flight, sitting bottom of the table with just four points from their opening seven games. Former Stoke and Crystal Palace manager Tony Pulis has joined ex-Tottenham boss Tim Sherwood as a reported candidate to fill the vacancy, should QPR owner Tony Fernandes decide a change is required. last_img read more

Cells Perform Nanomagic

first_imgThe cell is quicker than the eye of our best scientific instruments.  Biochemists and biophysicists are nearing closer to watching cellular magic tricks in real time but aren’t quite there yet.  They know it’s just a trick of the eye, but it sure is baffling how cellular machines pull off their most amazing feats.  Think, but don’t blink:Knot Wizardry:  Proteins needing a fold go into a private dressing room (05/05/2003).  The most glamorous and well-equipped room, the GroEL-GroES chaperone, helps the star emerge just right.  How it does this is as puzzling as watching a magician untie a Gordian knot under a kerchief.  There are thousands of wrong ways a protein could fold; how does the chaperone always perform the trick correctly?  Some of the bonds between domains (disulfide bridges) are a long way apart.  What brings them together, and what keeps the wrong bridges from forming?    Some scientists at Howard Hughes Medical Institute, writing in PNAS,1 cheated and built the chaperone with one door open so they could peek inside.  They still couldn’t figure it out completely.  Something in the chaperone creates conditions that favor the correct “native” fold, but also fix the mistakes before the prima donna protein emerges.  Somehow they do this without any ATP energy cost.  “We conclude that folding in the GroEL-GroES cavity can favor the formation of a native-like topology, here involving the proper apposition of the two domains of TG [trypsinogen, the enzyme in the experiment]; but it also involves an ATP-independent conformational ‘editing’ of locally incorrect structures produced during the dwell time in the cis cavity.”Speed Solve:  Maybe you’ve watched a blindfolded man solve a Rubik’s cube in seconds and wondered how it was done.  You can imagine the bewilderment of German and Swiss scientists watching a protein fold in far less time.  Protein chains of hundreds of amino acids have to explore a vast space of possible folds yet arrive at the one correct fold, often in fractions of a second.  These scientists, writing in PNAS,2 used lasers to try to figure out in slo-mo how this happens.    As with a Rubik’s cube, there are billions of ways a protein could fold incorrectly.  Parts of a nascent protein chain form loops in the process of solving the puzzle.  “Exponential kinetics observed on the 10 to 100-ns time scale [ns=nanosecond, a billionth of a second] are caused by diffusional processes involving large-scale motions that allow the polypeptide chain to explore the complete conformational space,” they said.  “The presence of local energy minima [e.g., loops] reduces the conformational space and accelerates the conformational search for energetically favorable local intrachain contacts.”  To catch these loops, they had to look fast.  “Complex kinetics of loop formation were observed on the 50- to 500-ps [picosecond] time scale,” they noted.  A picosecond is a trillionth of a second.  Good thing they had lasers that could flash up to a femtosecond (quadrillionth of a second), or it would all be a blur.Levitation:  With a feat better than defying gravity, “Cytochrome c oxidase catalyzes most of the biological oxygen consumption on Earth, a process responsible for energy supply in aerobic organisms,” wrote a Finnish team also publishing in PNAS.3  To do this trick, the enzyme has to go against the force.    Scientists like to talk in dispassionate language, but they called this enzyme “remarkable,” so they must have liked the magic act.  “This remarkable membrane-bound enzyme also converts free energy from O2 reduction to an electrochemical proton gradient by functioning as a redox-linked proton pump,” they remarked about the remarkable.  The way this pump works has “remained elusive,” even though most of the structure has been known.  With special spectroscopic and electrometric techniques, they were able to observe the trick in real time.  Abracadabra led to eureka: “The observed kinetics establish the long-sought reaction sequence of the proton pump mechanism and describe some of its thermodynamic properties.”  OK, tell us.  What’s the secret?The 10-microsecond electron transfer to heme [iron complex] a raises the pKa of a “pump site,” which is loaded by a proton from the inside of the membrane in 150 microseconds.  This loading increases the redox potentials of both hemes a and a3, which allows electron equilibration between them at the same rate.  Then, in 0.8 ms, another proton is transferred from the inside to the heme a3/CuB center, and the electron is transferred to CuB.  Finally, in 2.6 ms, the preloaded proton is released from the pump site to the opposite side of the membrane.So, there.  Now you know the trick.  Uh, how’s that again?  Actually, they only figured out part of the trick; “some important details remain unsolved,” they confessed, “e.g., the identity of the proton-accepting pump site above the hemes.”  Their diagram of the enzyme looks for all the world like magician’s tightly-cupped hands, with the active site secreted within.  Maybe this could be dubbed sleight-of-enzyme.In the introduction to this last paper, the authors described how the enzyme is essential to all life.  It is a key player in the transfer of electrons and protons that feed the ATP synthase motors that produce ATP – the universal energy currency for all living things.  Water is produced in the process that generates oxygen (in plants) and consumes it (in animals).  These reactions would not occur without the machinery to drive them against the physical forces of diffusion.    The scientists are converging on a mechanical description of how the pumping action works.  “Each of the four electron transfer steps in the catalytic cycle of CcO [cytochrome c oxidase] constitutes one cycle of the proton pump, which is likely to occur by essentially the same mechanism each time,“ they said.  “Here, we report on the internal electron transfer and charge translocation kinetics of one such cycle, which is set forth by fast photoinjection of a single electron into the oxidized enzyme.”1Eun Sun Park, Wayne A. Fenton, and Arthur L. Horwich, “Disulfide formation as a probe of folding in GroEL-GroES reveals correct formation of long-range bonds and editing of incorrect short-range ones,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0610989104, published online before print February 5, 2007.2Fierz, Satzger et al, “Loop formation in unfolded polypeptide chains on the picoseconds to microseconds time scale,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0611087104, published online before print February 6, 2007.3Belevich et al, “Exploring the proton pump mechanism of cytochrome c oxidase in real time,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0608794104, published online before print February 9, 2007.We may not be able to tell how it’s done, but we all know that a stage magic trick is just an illusion.  But a good trick doesn’t just happen, either.  It takes a lot of intelligent design to put on a good show.  Split-second timing, carefully engineered props, trained assistants, planning, and precise manipulation are all required.  If and when we figure out all the cell’s tricks, it should produce even more awe than a childish belief in magic.  It should produce a deeper respect for the planning and execution of a well-designed show – and a hearty round of applause.    Need we say how disappointing it was for Nature to submit this Stupid Evolution Quote of the Week about the same time as this last paper appeared: “The invention of oxygenic photosynthesis was a small step for a bacterium, but a giant leap for biology and geochemistry.  So when and how did cells first learn to split water to make oxygen gas?” (John F. Allen and William Martin, “Evolutionary biology: Out of thin air,”  Nature 445, 610-612, 8 February 2007).  Shamelessly, they continued on and on: “Biologists agree that cyanobacteria invented the art of making oxygen, but when and how this came about remain uncertain.”    It appears that some childish scientists still believe in magic.  We hope the growing brightness of design emerging from cell biology will not cause too much pain as it shatters their illusions.  If they maintain their illusions in spite of the evidence, though – well, willful blindness is its own punishment.(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Ohio Ag Weather and Forecast – August 9, 2018

first_imgShare Facebook Twitter Google + LinkedIn Pinterest We are dry today over the state. The past few days have been very difficult forecast-wise, due to seemingly plentiful instability, both ahead and behind a frontal boundary working into the eastern corn belt. Today we see a brief moment of stable conditions and a lack of any new moisture being introduced into the state. That should allow us to be dry and sunny in most areas, with temps near normal.Scattered showers arrive in NW Ohio by tomorrow morning, and then spread south and east through the day. We think action for Friday is mostly north of I-70, although we wont rule out a few incursions father south. Then, as the moisture continues to move for Saturday, we have scattered showers from I-70 south to the Ohio River. Combined rain totals for the event, both days, will be from .1″-.7″ with 80% coverage.We are mostly dry Sunday morning, but showers return for afternoon and evening. Rain continues through Monday and Tuesday, with totals for the period at .25″-.75″ and coverage at 100%. WE are dry for Wednesday as the moisture moves off south and east.Rain is back on Thursday with another .25″-.75″ over 90% of Ohio. We are continuing to take a very conservative approach to this system, but will point out once again that the European model still wants to develop a massive storm complex with a strong low, heavy rains and severe weather, particularly in the NW and north central part of the state. At this time, we still do not see any reason to ramp this up that far.After a bit of a lull, we have to allow scattered showers in for Friday and Saturday with only 40% coverage. These may bring up to a quarter inch of new precipitation, but we also think that if there is a weak link in the forecast, it is here…these could fall apart or just come as some clouds. We are dry for Sunday the 19th into the 20th. The map at right shows potential rain totals over the next 10 days.For the rest of the extended 11-16 day forecast period, we have scattered showers for the 21st through the 24th, a pattern very similar to what we are seeing now. So, overall, our forecast is wetter this morning, with no excessive moisture, but good chances for a majority of our forecast pattern. Our atmosphere is getting well primed to trigger these kinds of days. Precipitation will be scattered over the period, and there will be many areas that miss out on action day to day. But over the coming two weeks combined, we all get nice moisture, enough to continue promote good crop conditions, growth and development.last_img read more
