This lease rider form may be used when you are involved in a lease transaction, and have made the decision to utilize the form of Oil and Gas Lease presented to you by the Lessee, and you want to include additional provisions to that Lease form to address specific concerns you may have, or place limitations on the rights granted the Lessee in the “standard” lease form.
Puerto Rico Surface Pits, also known as Puerto Rico Sinkholes, are geological formations that occur on the island of Puerto Rico. These natural depressions in the ground are characterized by their varied shapes, sizes, and formation processes. Puerto Rico Surface Pits occur as a result of several geological factors such as dissolution of soluble rocks, collapse of underground cavities, or erosion processes over time. One type of Puerto Rico Surface Pit is known as a collapse sinkhole. Collapse sinkholes typically occur when an underground cavity, often formed by the dissolution of limestone or other soluble rocks, collapses due to the weight of the overlying sediments. These sinkholes can form suddenly and can be extremely hazardous, as they can cause significant damage to infrastructure and pose risks to human safety. Another type of Puerto Rico Surface Pit is referred to as a solution sinkhole. Solution sinkholes develop gradually over time through the continuous dissolution of underlying soluble rock layers, such as limestone or gypsum. These sinkholes tend to have a more circular or oval shape and are often surrounded by vegetation. Solution sinkholes can vary in size, ranging from small depressions to larger, more expansive formations. An additional type of Puerto Rico Surface Pit is the subsidence sinkhole. Subsidence sinkholes are commonly formed when underground water sources, such as aquifers, are depleted due to excessive groundwater extraction. This causes the ground above the depleted aquifer to sink, resulting in depression on the surface. These sinkholes can pose significant risks to infrastructure and can lead to the destruction of buildings or roads. Puerto Rico Surface Pits play a significant role in Puerto Rico's geological landscape, contributing to the unique topography of the island. It is important to note that these sinkholes can occur in both rural and urban areas, making it essential for residents and authorities to be aware of their presence and potential hazards. Regular monitoring, proper land-use planning, and engineering measures are crucial in mitigating the potential risks associated with these surface pits.
