Ann: Block 9, Alameda-3 Appraisal Update, page-93

it does not add up marti 5 flowed light oil , A1 was shut down due to uncontrollable pressure and oil and gas influx into the string ,so it must be the muds ,the whole idea of drilling muds are to lubricate and help prevent oil gas water from entering the bore ,basically to BLOCK UP THE PORES IN THE WELL
the fact that they were unable to get clean oil with out drill muds says blocked up but there was some oil , but the smart thing was to suspend marti and move up to the alemeda and get more advise on what to do diamite




Drilling Design and Selection of Optimal Mud WeightBernt S. Aadnøy, Reza Looyeh, in Petroleum Rock Mechanics (Second Edition), 201910.2.3 Higher Mud Weight; the Whole Truth?The mud weight is a key factor in a drilling operation. The difference between success or failure is nearly always tied to the mud weight program. Too low mud weight may result in collapse and fill problems, while too high mud weight may result in mud losses or pipe sticking. Table 10.1 lists the effects of high mud weight on drilling problems, and as can be seen, high mud weight reduces the top six borehole issues while it is not so advantages for bottom five.https://www.sciencedirect.com/topics/engineering/mud-weight
