Aadnøy, in Methods for Petroleum Well Optimization, 2022 5.2.1 Effect of parameters on hole cleaning The selected mud pump should also be capable of providing pressure that is strong enough to overcome the total pressure loss and pressure drop at the bit in the circulating system at the total hole depth. The minimum required mud flow rate demanded by the borehole geometry from the mud pump is estimated based on the minimum required mud velocity, which should be higher than the drill cuttings slip velocity. The minimum required mud flow rate from the mud pump is equal to the minimum required mud velocity times the maximum possible cross-sectional area of annular space during drilling. Plastic viscosity and yield point are the two parameters used to describe the rheological characteristics of Bingham plastic fluids. For Newtonian fluids, viscosity is the only parameter describing fluid rheological characteristics. Mud properties that influence the type of pump include mud weight and rheological properties. The selected mud pump should be capable of providing mud flow rates that are high enough to transport drill cuttings to the surface at all stages of drilling. This chapter presents theory and procedures for selecting mud pumps. IR can help with both GST and provisional tax due.Boyun Guo Ph.D, Gefei Liu, in Applied Drilling Circulation Systems, 2011 Publisher Summary “We are also extending the Commissioner of Inland Revenue’s ability to apply flexibility for tax payment dates and terms to assist firms with cashflow pressures,” David Parker said.Īny businesses struggling to pay tax because of the impacts of COVID should log on to myIR to see if they can delay starting payments to a later date, or if any part of the tax could be written off. This change will mean interest will only start accruing at the beginning of year three. “Cabinet has also agreed to remove the first two years of accrued base interest from all borrowers who have, or will, take out a loan under the scheme. “The top up loan will allow those firms that have already accessed a loan to draw down an additional $10,000 with a new repayment period of five years and the first two years being interest free. Revenue Minister David Parker said changes were also being made to the Small Business Cashflow Loans Scheme to increase the amount of funding available to eligible businesses through the introduction of a ‘top up’ loan.
“We looked closely at whether we could offer sector specific packages but the definition of who is in what sector, and the need for cashflow to be provided quickly meant that was not a feasible option to reach the most affected,” Grant Robertson said. A business is eligible if they can show a 40 percent or greater drop in a seven day period since 16 February this year compared against a typical seven day period in the six weeks before. “We have set a higher threshold in terms of revenue loss than previous support in order to target those most affected. We will continue to closely monitor the situation and have the option to extend the payment if this if necessary. This reflects the international experience that the peak of the Omicron outbreak should pass after about six weeks. “It will be available on a fortnightly basis for six weeks – so three payments in total.

There are a range of reasons for this, but it is clear that the impact is putting a number of viable businesses at risk of not being able to operate.Įach COVID Support Payment will be $4000 per business plus $400 per full-time employee, capped at 50 FTEs or $24,000, this is the same rate as the most recent Transition Payment.Īpplications for the first payment open on February 28, with payments starting from March 1. We can see that the majority of the economy is operating close to normal, but in some sectors, like hospitality and events, there has been a significant drop-off in business. “With the settings of the framework most businesses can open and operate relatively normally, even at red. “As I said back in October when we announced the traffic light system, the Government has been monitoring the impact of the COVID Protection Framework on businesses and the economy,” Grant Robertson said. A new targeted COVID Support Payment will be made available for businesses struggling with revenue during the Omicron outbreak.
