New oil fields are most easily found where oil is already being drilled.  There are a number of ways to test for oil.  Soil gas surveys can assist in the discovery of oil.  These surveys measure a soil sample for trace amounts of light hydrocarbons (the tell-tale chemical signals of oil).  Soil gas surveys should be the first option when investigating whether a region contains oil because the test is relatively low-cost.  Seismic imaging can also help locate oil deposits.  Seismologists, armed with devices known as geophones, can bounce sound waves off underground rock and listen to the echoes the sound waves produce.  Analyzing the echo patterns can provide accurate imagery of subsurface geology, including pockets of oil and other fossil fuels. After conducting the requisite research, an oil company should consider potential complications with their drilling plan and address them in their proposal.  How much money is allocated for the drilling project?  How long is the well expected to be productive?  What is the desired return on investment?  Ask hard questions and try to anticipate specific dates for key events -- such as the full assembly of the oil rig, commencement of oil production, and well abandonment -- over the course of the well's life. Conduct research into the oil market.  There are lots of alternatives to oil today, including solar, electric, and biofuels.  Consider recent trends in the price of oil and use it determine if drilling a new oil well is a sound investment.  Is there a glut (overproduction) in the market?  Are more wells expected to open elsewhere soon?  If the market is volatile, with lots of wells opening and then shutting down soon after, consider waiting for a less tempestuous market before drilling. It may be necessary to build a road to access the drilling site, or purchase boats if drilling an offshore well.  Water, electricity, food, and sanitation equipment will also need to be accounted for.  If drilling in a more developed urban area, infrastructure costs will be less significant. Preparations will vary depending on the type of environment the well is being drilled in.  An offshore well, for example, will require a different set of equipment than will a conventional terrestrial (land-based) oil well.  Likewise, preparations for a well drilled into frozen tundra will differ from those of a well drilled in the desert. To prepare drilling in an offshore well, a base consisting of permanent casting will need to be positioned on-site.  The oil company will then affix a template (a large box resembling a cookie-cutter) to the base to to provide guidance for future drills.  The drilling platform itself will then be attached to the template. In addition to scientists and technical staff, drillers and maintenance personnel will be needed to oversee daily operations.  Geologists will study surface features, terrain, and rock and soil types. Consult ecologists to ensure local wildlife will not be adversely affected. Lawyers and company officials will help ensure all the necessary paperwork is in order. Be sure to enlist the assistance of construction crews help prepare the site. Hire seasoned drillers.  They should be in excellent physical shape and enjoy working with machinery.  A well 10,000 feet deep requires approximately 50-75 people to operate. Obtain any permits, lease agreements, titles, etc., needed to drill in the area. Measure any impact the drilling will have on the environment and report it to the appropriate authorities.  Paperwork requirements vary by state, but some of the most common types of permits needed include:  Registration for well operation.  This is the most basic declaration by a company describing their intent to drill, including where, how, and to what depth they will drill the well. Designation of agent or operator.  This form is required when a company or individual is drilling the well on behalf of another company or individual, and identifies which employees are allowed to file paperwork and make decisions regarding the drilling process.  Location assessment to determine if the well will disrupt or endanger local ecosystems or aquifers.  Letter of credit, financial assurance statement, or performance bonds.  These forms (and their accompanying fees) act like a deposit in a rental agreement, and ensure that the oil company will plug, sell, or otherwise decommission the well in accordance with local law and best practices.  If the well is being reopened, is changing hands, or is being altered, complete the appropriate forms will need to be completed. Check with the governing land management agency to ensure all paperwork is filled out properly before drilling begins. Mark the targeted area for drilling.  Ensure all personnel are briefed on safety regulations and enforce them strictly.  Once drilling is set to commence, place buoys around the area if drilling an offshore well.  Use GPS coordinates to mark a designated spot when drilling on land. Install a blowout preventer (BOP) before beginning any actual drilling.  The BOP contains high-pressure safety valves which prevent oil from escaping in the event of a blowout.

Q: Keep in mind that ammonia can have harmful effects when inhaled. Improve the air circulation. Open windows and doors, switch on exhaust fans, and/or set up other fans to get the air moving. Chances are that in areas like bathrooms, your options for improving airflow are pretty limited. In this case, be sure to wear a respirator that will filter out the fumes. Or just wear one anyway to be extra safe- A plain paper face mask depicted in the graphic will not protect you from ammonia fumes. You need an activated charcoal cartridge respirator fitted to seal to your face and designed to absorb ammonia. Many hardware stores can assist you in finding the right respirator, and you can also find more information about them online.. First, improve the ventilation in the area you’re mixing this if you’re doing so somewhere other than the area that needs cleaning. Then mix equal parts ammonia and water either directly in a spray bottle or another container before pouring the mix into your bottle with a funnel. Once your solution is mixed, squirt an even amount over the moldy caulk. Wait five to ten minutes for it to settle in and start killing the mold. Then scrub the sprayed caulk with a small brush. Wipe the caulk down with a cloth or paper towels to remove all traces when finished. If the first application didn’t kill or remove all the mold, try again. If repeated tries don’t seem to be doing anything, use another cleaner. Keep in mind that ammonia can be an effective mold killer with non-porous surfaces, but often has difficulty with porous ones like caulk. Be aware that caulk may look clean after you’ve scrubbed and wiped it down, but mold may still be present. If it reappears soon after your attempt with ammonia, treat this as a sign that the mold’s roots are too deep in the caulk for the ammonia to reach it effectively. Move on to another solution.
A: Ventilate the area. Wear a respirator. Make your solution. Spray and scrub. Repeat and evaluate. Use another cleaner if the problem returns.

Article: In Campaign mode, you get to choose nations you wish to play as. The nation you choose can have a big impact on how quickly you can become rich. Great Britain is a very good choice for players that want to get rich as quickly as possible due to the large number of ports you start out with. Spain also has an advantage because of trade routes and having neighboring countries that possess huge influence (like France). If you're new to the game, it's best to choose an easier level to give you time to get used to the game system, menus, and features as you go on.
